Professor AGoAsSW. spoke for an hour, giving his viemws of a new theory of animal developm-ent,. lie began by saying. —We are here to inaugurate the Geological i[all, which ha-s grown out of tlhe geological survey of the State. To make the occasionl memorable, a distilguished stateslman of your own State, anid Mr. FRANK C. CGRAY, were expeet:ed to be l)resent and address you. The p)ressure of public dtties has detained jMr. SEWARD,t and severe sickne.ss lhas detained Ahi. (I^t. I deeply lament that the occasion is lost to you to hear my friend Mr. Gn^AY, who is a devotee to science, anid as warnm-hearted a friend as ever I knew. Nightbeforel'ast I was rcquested to attist il taking their p)ace —I, who ami the most unfit of men for the post I never made a speech. I have addressed learned bodies, but X lack that liberty of speeelh —the ability to present in finisiecd style, and with tlhat rich imlagery which characterize the words of the orator, t*he tlthoughts fitting to such an occasion ns this. lie would limit himself, eto continued, to priesenting f0some motiv(s )DE DIOATION OF GOO(OOAG ItGALhAL, 5 why tle comnlmunity 1should patronize science, and foster such institutions as tlhis. We scientific men regard this as an occasion of the highest interest, and thuts do not hesitate to give the sanction of the highest learned body of the country as an indorsentent of the liberality of this Sta to. The gological survey of New York has given to thex world a n w nomenclature..No geologist can, hereafter, describe the soveral strata of the earth without referriing to it-. Its results, as recorded in your published volumes, are treasured in the mnost valuable libraries of thile world. They have made this city famous; and now, when thile scientific geologist lauds on your shore, his first question is, " Which is the way to Albany I I want to see your fossils." lint Paleontology is only one branch of the subject, and many others your survey has equally fostered. IIC next proceeded to show t t, orgaMtzed bi Jgs wxere organized with reference to a plan, which the relations between diffirent animals, and between different plants, and between animalfs and tplants, everywhere exhibit; —drew sections of the body of a fish, and of the bird, and of retan, anid pointed out that in each theore was the arno central back-bono, the cavity above and the ribbed cavity below thile flesh on each side, and the kint over all- —.sChowing that the raker of each possessed the same thoulght- -followed the stame pIlan of structure.

There are only four of thcese great types; or, said he, may I not call tiher the four tunes on which J)ivinity has Jiayedt the harmonies t]hat havy peopled, in living and beautiful reality, the whole vorld? P'ROr''sso tt'IiiCOCK ON nitSO:sc;Ecrs. EtAS-rus C. BtCYM:ns}m, E:sq, of New York, introduced Prof. Ifnrrutcocx, of Amhterst, as a genttleman wiose namne wa.s very fatniliar, who had laid aside, voluntarily, the charge of one of the largest colleges iti New England, but who could never lay side the honors hle had earned in the literature and science of geology. After a few itntroductory observationts, P'rof. Jtrretucocx said:.. Thiis, I believe, is the first exampnile in whmich a State Govecrnment itt our country has erected a mrnuscumn for tlhe exhibitioti of its natural resotturccs, its minieral and rock, its planits antd ainiIals, living and fossil. And this seems to tue the most alppropriate sp)ot in the conAttry for placing the fitst geological hall elected by tht (G4overmnett; for the County of Albany was tlhe district where thile first geological survey was undertaken, ont this side of the Atlantic1 and, perhlaps, the world. This was int 1820, antd ordered by that emuinetit philatnthropist, Steplhen Vati Rensselaer, who, three years later, appoitnted P'rof. Eaton to survey, in like mannier, tie whole region tanversed by the lE'rie Catal. This was the commencementt of a work, which, duil'ing thel last thirty years, has had a wonderfull expansio, reaching a large plart of thte States of tllhe iJon, as swell as Cunada, Nova Scotia, and New JBrunswick, oand, I might add, several Euroceant coutitries, where tile mnagnitficent surveys now itt progress did not comttamtice till after the survey of Albany tand etiesselaer Coutitiv.. Itow glad are we, thlterefore, to fintd on tifis spot the firt Museuan of Economical Geology on tlhis side of the Atlmitic I Nay, embracing as it does all the depattument of Natural Hlistory, I see in it more thant a European BMtsctum of ecotormiceal Gcology, 8pletdid though they are. I fancy, rathei, that 1 see here thile germl of za Cis-Athnatie Brit4ish Mtuseum, or Garden of Plamtds. North Carolina was the first State that ordered a geological survey; and I have the pleasutre of seeing before mte the gentenman who executed it., and in 1824-6 )thblished a report of 140 pages. I refer to'Professor Olmnsfead, who, though hle has since won brighter laurels in another department of science, w!ill always be honored as thte first comnititssioned State geologist ii ottr land. G P)]'DIGATION OF GEOLOGICAI L I ALL. Of the New York State Survey he said:This sturve.y has developed the older fossiliferous rocks, with a fullness anl distinctnes unkun2own aelsewhere. hience Eu11ropea, savaus study the New York Reports with eang0ernes. In 1850, as I entered the Woodwardlian Museum, in tho University of Cambridge, in England, I found Professor McCoy hbusy with a collection of Silurian fossils before hint, which he was stludyiNng wtith Hall's first vol1ume of I'aleontology as his guide; and in the splendid volumes, entitled British P 0tl0ozoric Rocks and Fossils, which Appeared last year as the result of those researches, I find Professor I tall denominated the grcat American Palcontologist. I tell you Sir, that this survey has given New York a reputation throughout the learned world, of which she may well be protud. Am I told that it will, probably, cost half a million Very well. The larger the sumn, tlhe higher will be the reputation of New York for liberality; and what other half million expended in our country, has developed so many nSew facts, or thrown so mauclh light upont the history of the globe, or won so world-wide atid enviable a reputation I And of Geological Surveys in general:. In regard to this matter of geological surveys, I can hardly avoid imaking a suggestion Ilcre. So large a portion of our0 country has now been exarnined, rore'or ltes thoroughly, by thtre several State governments, that it does seem to, me the tinie has com'e when tile Nattional goveri-nent should order a survey — geological, zoological, antd botanical...of the whole country, ontt such a liberal and thorough llaln as the sur8veys in Great Britain aret now conducted; in the latter country it being understood that at leasts thirty years will be occupied in the work. Could not the distinguished New York statesman w ho was to have addred"ed us to-day be induced, when the presclit great struggle in which he i, engaged shall have been brought to a close, by a merciful Providence, to introldute this subject, and urge it upon Congress? And would it not be appropriate for the American A.ssociation for the Advaincemtcnt of Sciene to throw a petition before the governmecnt for such ani objeet? Or might it not, with the conisent of the eminenft gentlenman t who has cliartge of tleto Coast Survey, be connectedtc therewith, as it is withl the Orditance Sutrvey in Great Britain. The history of the Aeicrican A.sociation was theni given:Prof. Matither, I believe, thrloughl Prof. Erninots, firstI suggested to the New. York Board of Geologists in November, 1838, ii a letter proposing a mttinber of pointtts for their consideration. I quote froml him the following paragraph. relnting to the meetitng. As to the credit lie has here given me of htwitg pe.r.sortially suggested the subjet., I can say ontly thlat I had beent in thile hait for sevelral cyats of imaking this mcetitig of scientiftce men a sort of hobby in my corrfCspondetuce with sutch. Whethert others did the sare, I did not theti, and do not now know. Were this thte proper place, I could go mtore into detail O titisl point; but I will m erely qiote Proll Mathier's language to the Board:-. *- * " * " Wotuld it ntot be well to suggest the propriety of a mIeeting of Geologists and other scientific metn of outr country at some cetitral point itext fall,.-....say at New-York or i'hiladelphtia? There are mtany (questions in our Geology fltha will irceive iew light e fron fiendly discussion atid tte cottmbined observations of various ittndividuals who have nioted thei in differentt parts of our eountt.ry. Such a meetinig has beeni suggested by Prof. IHithcock; and to ane it seems desirable. it woutld undottbtedly be an advanttage not only to science tbut to the several surveys that are niow in progress And( that may i fultur bei authorized. It would tend to mruake known our scientific mnci to each other perottally, give themni miore confidence in each other, anid causo tItens to concentrate their obsetrvation on tltose questions, that are of interest in eitlter Av scientific or econotmical poitt of view. More qtuestionts may be satisfactorily DE)DCiOATION OF ( 0IIOJI,0 IOAJ, hALt,,. T settled in a day by oral discussion inll such a body, than a year by writing and pfu blic atio."*a Though the Board adopted the plan of a meeting, various causes delayed the first over till April, 1840, when we assemblcd in P'hiladelphia, and spent. a week in most profitableo and pleasant discussion, and the presentation of pape r:. Our number that year was only 18, because confined almost exclusively to the State geologists; but the next year, when we met again in Philadelphia, and a more extended invitation was given, about eighty were present; and the members have been increasing to the present time. Blt, in falct, those first two tmeetings proved the type, in all things essential, of all that have followed. The prilneipal changes have been those of expansion antd the consequent introduct.ion of many otrher branches of science with their eminent cultivators. In 1842, we chang'ed the name to that of the Association of American Geologists and Naturalists; and in 1847, to that of the American Association for the Adtvancem ent of Science. I trust. it has not Cyet reachedt its fullest tdevelopmecnt, as our country ant its scientific men multi0 1 ply, andt new fields of d(liscovery open. Prof. it. said of thlis particular occasion:. —... We may be quite sutre t hat this ifall will be a center of dee1p interest to coming generations. long after we shall have passes away will the men of New-York, as they survey these imonmmrents, feel stimulated to engage in other noble- enterprises by this work of their progenitors, andi fronm many a distant part of the civilized' world will men) comle here to solve their sietentific quest1ion-, antd to bring far-off regions into comparison with this. New-York, then, by her liberal patronage, has not only acquiretd an honorable name among those living in all ei;vitized lantds, but has secured the voice of Hlistory to tranlsmit her fame to far-off generations. 8sIR iVIILAMI LOOAN ASK8 11tI WAY'iTO ALBANY,.")

The Survey of Canada had been ordered, and the Cormission of live years twice reneved; and the last time, the provi ion for it wasv more tlhan doubledi. It happened to him, as Mr. Agassiz had said: after erossing the ocean first, the first tiling lie asked ws, "IWhich is the way to Albany?' and when he arrived here, he found that with the aid of Prof. [aflt's discoveiries, lie hlud only to take up the different formations as lie had left them on the boundary tlne, aiid follow them into Canada. It was both a convenience and a neee.sity to adopt the New-York onomenclature, which was thus extended over an area six times as laige as New-'York. In Paris lie heard DC Verniei using the words Trenton and Niagara, as if they were household words. Ile was delightedt to witness the impatienee with Whlich BIarron inquired when the remaining volumes of the Palenontology of,New-York would be publisihed.

Prof. CHARLEs i)Av 1s was introduced by Ex-Covernor S:YmOURvt, and spoke briefly, butt humorously annd very much to the point, i'i defetse of th-e practical character of seicntil'e researlch s. lie said that to one accustomed to speak o.tly on the abstract qtuantities of number and space, this was an unusual oceasiot, and this anti umiusal audience; and inquired how he could discuss the abstract forms of geomretry, white lie saw before him, in such profusion, the most beautiful real forms tfat lProvidence has voutehsafed to the life of man. lie a'op osed to introduce ad decvelop but a single train of thought. —.the unchangeable connection between what in comrnon language is called the theoretical nid practical, but in more teelihical phraseology, the ideal aid the actua!l.'thie actual, or trite 1)actical, consists in the Auses of the forces of nature, according to the laws of nature; and here wve must distinguiksh betw\een it and the emlirical, which uses, or attempts to use, those forcees, without a kitowlvedge of the laws.'Tie trite practical, therefore, is the result, or actual, of an antecedent ideal. The ideal, full and complete, must.exist in the mind before thte actual can be brought forth according to the laws of scientce. Who, then, are the truly practical men of our age? Are they not those who are engaged most laboriously and successfully ill investigating thile great laws? Are tltey not those whto are pressing out the boundaries of kinowledge, aid conducting tlhe mind into noew and unexplored regions, where there may yet be discovered a California of undevevloped thought? Is not thte gentlematinfrora Massachusetts (Plrofesor Agassiz) the most practical maitn in our country in the department of Natural history, niot because lie lins collected the greatest number of specimens, but because lie has laid open to us till the laws of the animal king(1o01'? Are the formitnilas written on the black-board by the gentleman frnom Cambridge (l'rof. Pierce) of no practical value, because they cannot be read by the ititistrueted eye? A siingle line may contain the lccelents of the motions of all the hteavenly bodies; and tlte eye of science, taking its staid-p)oiitt at the center of gravity of the system, will see in the cqation the Iurioharoiotus revolntionis of till the bodies which circle the lieavens, It is such labors and such. generahizsations that have retndered his tname illustriolus in the history of matheImatical seicience.

Thie Mleridintl Circle an( Tranls' it instrument were ordered friom Pistor A Martins, the celebrated manufacturers of Berlin, by who0lll tfhe new instrumtent at Ann Arbor was rmade. A numttlber of improvelnents lhave been introdulced in thel Albany instruments, not p)erhaps all absolutely new, but an eclectic coinbinaltionl ofi late adaptations with new improvements. D)r.

The English instrumentl is tIte inistrument of the engineer; the (crmatll, tile imlstrtument of the artist. Iti orderingl tthe instrtilirnelts for the A lbany Observatolry, the Doctor preferred the German type and discarded the heax ier English.' lie instanieed, as a specimen of the latter, tIhe new instiun11en at Gt reenwichl, recently erected under the superintendeince of the Astronomer Royal.

T'ile view for miles is unhnlpeded; and the Observatory is belted about'with woods and verdant lawns. There could not be a finer location or 1a purer air,'le )plateau contains some fifteen acres,'The Observatory is constructed il thle fornmt of a Latin cross,. Its eastern arm is nlt apartment 22 by 21- feet, in which the meridian circle is to be lplaccd. Thle western artm- is a room of thle sallme dimensions8, intended for thle transit instrument. From the north and south faces of both rooms are semlii-circular apsides, projecting 6 feet 6 inches, containing the Collimator piers and the vertical openinigs for observation. Thle entire length of each room10 is, therefore,? feet,. In the northern arm are placed thie library, 23 feet by 27 feet; two coalputing rooms, 12 feet by 23 feet each; side entrance halls, staircases, &e. The southern arm cont ains t.le principal entrance, consisting of an arched colonnade of four tuscan collumns surrounded by a pediment:. A broad flight of stone steps leads to this colonade; and through thie entrance door beneath it to the maini central ball, 28 feet square, il which are placed (in niches) the very beautifull electric clock and penduluna preselnted by IErastus Corning, lsq. The center of this ball is occupied by a tmassive plier of stone, 10 feet square, passing from the basemrent into the dlotte above, and intended for the stt)pport of thle great heliomrteter. i)irectly opposite the entrance door is a large niche, in which it is proposed to plaee tlhe bust of thle late Mr. i)udley. Irmediately above this hall is the equatorial room, a circular apartlment, 22 feet 6 inchls in diameter, and 2,4 feet high,l covered by a low conical roof, in which and in the walls are t.he usual observing slits.'lhe druml, or cylindrical portion, of this roomt is divided into two parts — the lower one fixed, time upper, rcvolving oni cast-iron balls moving inl grooved metal plates, can conmmland the entire horizonl. The building is ill two stories —:- the upper of brick,'with freestone quoins, impost. and'window and door dressings, rests upon a rusticated basement of freestone, six feet hi gh. The style adopted is the nmodern Italian, of which it is a very excellent speciimen.

The piers for the M[eridian Circle and Transit have, after careful investigation, been procured from the lockport quarries.

It Nwas built at tlhe itersection 10tG 3ORATI' ON. of Yonker's and lfiandelaar's, better klnown to yout as State and Market streets. Ptublic and private liberality codperated in the ilmplortant work. Thse authorities at the Fort gave fifteen hundred gutilders; the patroon of thatcarl.y day, with the liberality co/.~val with tte name and the race, contributed a thousand; while tihe inhl1abitants, for whose benefit it was erected, whose numbers were small aind their resources smaller, contributed twenty beavers " for the purchase of an oaSken pul)pit ill {olland."

In eight years more, New Netherland becomes New York; Fort Orange land its (depenent hamlet assumes the name of Albany. A century of various fortlle succeeds; the scourge of Frlenchl and Indtlan wiar is rarely absent from the hlind; every shock of European policy vibrates with electric rapidity across the Atlantic; but thle year 1756 findls a population of 300,000 in your growing province. Albany, however, rmay still be regarded almhost as a frontier settlement. Of thte twelve counties into which the province was divided a hundred years ago, tile coomity of Albany comlprehended all that lay north and west of the city; and the city itself contained but. about three hundrdtt and fiftyt houses.

WIrAT, s AN ASTRONOMWAl, O[StiRVAtoR'Y? An astronomical observatory, in thlie general "acceptation of t:le word, is a building erected for t(le reception and )approplriate use of astronomical instrultients, ai(d t(tie accoimmod10 ation of tlhe rmen of science employed in making atttd reducing observatiolns of tile heavenly bodies. Tl1hese instiru1ients are mailly of three classes, to which I believe all others of a strictly astrononmic.al character may lie refe'tred. 1. The instruments by which ttlet heavens are inspected, witth a view to (iscover thie existence of those celestial bodies wiichi are nlot visible to lthe naked eye (beyond all comparisorn more numerous thaln those which are), ansd the maglitiudle, shapes, and other sensible qualities, both of those which are and those which are not thus visible to tle unaided sight, The instruments of this class are designated by the general iame of Telescope, and are of two kinds, -(lthe refitacting telescope, whlich dlerives its magnify3iin g power t I N. 21 fiom a systeml of convex lenses; and the reflecting telescope, which re-ceives the image of thle heavenly body upon a coneave mirror, 2d. The seconld class of instruments consists of those which are designed principtally to mlleasure tihe angular distances of the heavcnly blodies from each other, and their time of passing the meridianl. l'he tranlsit instrument, the meridian circle, the mural circlet, the helioleter, and tlhe sextant, belong to thlis class. The brilliant discoveries of astrolomy are, for tlhe most p art, made wvithl tlhe first class of instlarmlnlts; its practical results wroutght out by thle second. 3d. Thle third class contains the clock, with its subsidiary apparatus,) for measuring the time anld making its subdivisions with the greatest possible accuracy; indispe-nsable auxiliary of all the instruments, by whichl the position)s anlld motions of thle heavenly bodies are observed, and measutred, and recorded. TilEl" TLEASCOPt, Thie telescope may be, likened to a wonldrous cycopeanl eye, endlued with supelrhman lpo\wer, by which theastronomt er extends the reachl of his vision to the ftilther lheavels, and survt ys galaxies antl d universes comp)ared with which the solar system is but, an atom floating in the aiar. The transit Imay Ibe compared to thle measuring rod which lie lays from planet to pltllt, and from st-ar to star), to ascertEIINIUAN SYSETZI. It is stpposed thftt il the very dtawn of science, P)ythagoras or his discipies explained the apparent ttotion of the hellavenly bodies about the earth by thie diurnal revolution of the earth oi its axis. But this tlheorSy, though bearing so deeply iimnpresseCd upon it the great seal of truith, simplicity, was in such glaring contrast with the evidetnce of the senses, that it failed of acceptance in antiquity or thle middle ages. It found no favor with iinds like those of Aristotle, Archimedes, llipparclhu, Pltolemy, or tany of the racute and learned Arlabian or me(tliteval astronomers. All their ingenuity and all their mathemllatical skil \were exhausted in the dteveloplnent of a wonderfully complicated and ingenious, but erroneous history. The great master truth, rejected for its sitmplicity, lay (lisregalded at their fect. At the second dawn of science, thte great fiact agnain b-)earmed into the mind of Copernicus. Now, at least, in that glorious; age which witnessed tlhe illnventioln of j)rinting, the great mecltanical engine of itellectual progress, andll the discovery of America, \e limay, expect that this long-hidden revelation, a seond timle proclaimned, wvill command the assent of mankind.
