AN ith this reduction of force, the perilous jcuirney was continued; but the hum- mocks became worse, and altliou^ii the distance was only about forty miles in a direct line from the v\'esi( rn coast, fourteen days were ronsunied in tlie jouriiex. 'I'he route they imrsued A\as ni'arly the same as lliat followed in ISof by Dr. Hayes nnder the direction of Dr. Kane, and an o|Fiiortniiit_\ was thus afforded to make some important additions and corrections to the sl^elcii of the slnire line which had fbrmerU been yiveii. it \\as tbund that a channel or soiiikI opeiiiuL;- westward from Smith's Straits, separated I'.llesmeri' Land from (irinnell Land, and that in the nioiitli of this sound are two lar^e islands, to one of A\liicli tlie name of l)ache. and to the otlier that of llenrv ^\■as i;'i\en. On tlie I'Jili of May Kennedy Channel was entered and the coast followed as it trends nearly due north to Uitter i>ay. This ])oint was reached on the Kith, when two of the ])arty became exhausted l)y fatiij;ue, and the exi)loration was continued f'n- three days Ioniser by Dr. Hayes and his assistant, Mr. (ieorije !•'. Knorv. and reached. May iMJi. the latitude sl'^ ;n', about forty-one nautical miles beyond the limit of exploration under Dr. Kane and on the ojiposite side of the chan.iei. To the hiiihest ])oint actually attained the name of Cape i.ieber was ^-iven. and that of Church to a remarkable peak in the ■\iciiiity. On the north of Cajie Lieber there opened a larire bay, to which the name ef Lady I'rauklin ]i;;d been assii,nie(l by Kane; also on the north \\m- seen a head- lai"i called Cape IJeech'}', and lieyoiid another liiLih jioint wbi( h ^^ as named, in honor of His Majesty the Kiiiii- of Denmark.

The chronoiiietric determination is very unreliable, althousj;h the indications of the three chronometers kept tolerably well toi:;ether as far as I'riJven, we find them, a month later, diverging to the extent of four minutes ; it is evident, therefore, that they sustained considerable disturbances in tlu'ir rate, undoubtedly produced by th(< con- cussions of the vessel with waves and ice.

TIu' meridian of Van Rensselaer Harbor, Dr. Kane's winter (juarters in lS.j;3-';)4-'.).">, is well determined astronomically by moon culminations, eclipses, and occultations, and by adding the geodetic difference of longittule between the two observatories, as measured on the track chart, a longitude for Port Foidk(> was obtained more in excess of its most i)rol)id)le value as tliat liy the chronometers was in defect.

Each set consists generally of eleven observations at intervals of ten seconds, semi-arcs are recorded, counted from the middle eitlu'r way. The azimuth of the plane of vibration was nearly N.

The following description of the Olist-rvatory was rec(>ived from Dr. Hayes: Th(< Port Foulk(> Observatory was a small frame structure, eight feet sf[nare, by seven feet high in th" c(>ntre, the roof jiitching only one way. It was covered on the outside with canvas, and was lined intin'iially with l)ear, seal, and other skins. To give greater warmtli and solidity the snow was, during the winter, lianked up around it, covering it almost comi)]etely. It was erected on the first of a series of terraces wh.ich lay northeast from the anchorage, and its foundation was thirty-eight feet above the mean tidid lev(d. The rock on which it stood was ])rimitive (a dark reddisii-brovvn syt'iiite), which rose on either side of the harbor into hills from six. I i 1 A ST 1!

The magnet is suspended in a box over the centre of the circle, the suspension tube is eight inches long. Two magnets, each three inches long and 0.3 inch in diameter, with mirror attached, are provided, also a coUimater magnet 3j inches long, and but O.O inch of outer diameter. Ordinarily the '\\or\ scale above the eye end of the telescope is used for reading the deflections when mirror magnets are suspended, for the determination of absolute declinations an extra telescope can be fast(>ned to tlie projecting arm of the ali to lie the following note resjjectiiii^ the mounting of the instrument.

( ii;{ ) IIKCOUI) AND KESULTS TIDA L ()r.Si:il VATTONS, The ohsorvations of the tidos miirlc l>y tlio Arctic Kx])r(lition of Dr. I. I. Tlitvcs, at Port Foulkc, Smitli Strait, in iSdO aiid ISdJ, consist of two series; in llir first !iro recorded the observed times and liei;,dits of lii^h and low water in Noveinher and December, IStiO, tlu' greater part of it com- prising half-hourly observations. The second series consists of observations of time and height of high and low water in June and July, ISdl. These observations were taken (>very ten minutes about the time of high and low tide. The total extent of these two s(-ts of observations is nearly two and a half months ; a few accidental interruptions, however, occur in each series. The tide gauge was of sim])lc and effective construction, as shown in the annexed wood cut. It was a pulley gauge mounted upon tlu; ice field in the harbor. The pidlcy .and rope were su])pi)rte(l by a tripod mounted ovir the Jiole cut through the ice ; the tide rope was anchored at the bottom, and, in the first series, was divided off in feet by proper marks ; in the second S(n'ies a pole was inserted upon which the scale of feet was marked. The tide- rope was kept stretched by a counterpoise; this weight rose and fell with the tide. A gauge of such construction may be lialjle to disarrange- ment from the following sources : the rope may stretch, or the ice-field may have a slow motion and consequently incline the rope, or the stone may drag along the slojiing bottom from the effects of currents or ice motion; if, from any cause, the ai>i)aratus fails. the zero level of the s( ide is easilv lost, and generallv cumiot Im- recovered.

Secondly, by niarking, at certain epochs, tlie half- tid(> level of the sea, whicli i.., subject to smalliT fluctuations tlian eitlier the aviTage level of high water or the average level of hiw water, we may ascertain any relative change in the level of sea and land produced by geological causes. All levelling operations must also be referred to a certain tidal level. Tiiirdly. since theory points out certain fluctuations in the tidal level of tlie ocean due to the differential action of the sun and moon, their study and coiiii)arison with oi)ser\atioii will bring them to a practical test. There are other interesting (piestions connected with the subject of our iiupiiry, na.uely, the effect upon the level of the sea, of a change in the atmospheric pressure as indicated by the readings of the barometer, and also the effect of the wind, with respect to direction, duration, and strength, upim the average height of the sea. The change of the sea level tor a given rise or fall of tiie barometer has only been ascertained for a few places, and the measures fail to show u satisfactory agreement. The effect of the wind is of an entirely local character. The mean, or more pro^ierly tho half-tide level, is tho one to which all heights should he referred; on tho average, therefore, we will have at high tide an ecpial sectional area of water above, and at low tide an e([ual sectional area of deficiency. Owing to the daily ineciuality and the half-monthly inecpiality, which have to be eliminated, the following process for finding the half-tide level was employed. DrAiiliAM A.

Ejfipf of Chaiirjrn of the Lunar Parallax on iJic Ilalf-monfJiIi/ InrqnaJilj/. — From a short series of observations, like the one now mider consideration, wo can only deduce ajiproximately the changes which the half-monthly inequality undergoes in conse(pience of variations in the lunar parallax, and the same remark applies to the changes produced by variations in the moon's d(>clination. The method followed in this discussion is nearly \\\v same for the parallactic and decliuiition effects, and api)lies for high and low water an\('r, not the parallax belonging to th(> e])och of high or low tide which was employed, but one anterior to that time, the retropositioh de|)ending on the retard of the tide as detc^rmined in the preceding article. As the average age amounts to nearly a day, the parallax preceding the d^tfect by that inter- val was used in the tabulation. No distinction is recpiired for npi)er or lower tran- sits. The lirst group consists of intervals and heights for parallax between 54' and 5T, the second for par;illax between 51' and 00'. The means beii.g taken for each hour of the moon's transit, the following tabh's were obtained. Tiie letter V stands f«,r parallax ; thi" ine([uality for the average parallax (57') is added from the pre- ceduig investigation. ■|' I PA I, (» i:s i: i; v a 'I' i u n s l-Vci TaIILK 111. — l,iiii;ir-|Mr;lllai'li(.' etVi'cl mi ihr Ihiir-liMiillily liiniiialily For liiijh water.

To render the diurnal iue([uality more consijicuous, the dots of the hif^li and of tin; low waters were each connected l)y a full line, and the circles by lines of dashes. Th(! vertical distances between this full line and the line of dashes are re-plotted on a straitflit axis (of abscissa^) and exliibited below eacli series of obser\ations, the first for hiirh, tlio second for low water. On the same axis zero declination (of tin' moon) is indicated by a small circle, and f^reatest north or south declination liy a small bar.

For the lower dia TTI is about three feet, and for the semi-dinrnal about seven feet, the f,Miatest and h-ast vaii!,'es for these waves are four feet and two feet nearly fur the first, and ten feet ami fonr feet nearly for the last. The diurnal wave '^v.i- diially increases iu sii;o from the time of the moon's zero declination to the time of its maximum declination, as shown on the I'late. The epoch of the diurnal wave appears to remain sensibly the same duriiif; the twenty days for which it has been brou^dit out ; that is to say, its high water appears to occur at noon, and consetjueiitly its low water at midniji;lit ; the variations from these hours are confined within an hour before or after. The Van llensselaer Harbor tides afforded but a bare jilimpse at the diurnal tide; which occurred between October 'M) and November '2'2, l.s.jij, there also its hi!j;li water ajipeared to han;^ about the hours two or thre(> after noon, and its low water the same number of hours af"ter midniirht; but ;is theory jioints out a different relation than that of solar time, ('//'/ ciiiiiiitjiii iithi o (/riuJitid kIoii: f.7il/li/it/ fri, and as our series is too short to show its conformity or non-conformity therewith, we an,' comiielled to leave this interestini^ liraiich of the discussion.

To ascertain the efi'cet upon the tciniieratnrc of a serene and ( huuh' atnio-iiheve. the temperatnre observed on dear days (or at least thrcc-iinarters clear), and on cloudy days (or at least thrcc-iiuarters cloudy), was conii)ared with the normal temp- erature of the day; a + ditference indicates \\armer, a — ditt'ereuce a colder day than the normal; for this investigation the year was a:,Min divided into tuo sia-onN. The cliitr days preponderate in the n-inli r season, the i/mn/i/ (l;iy> in the vninimr season; thus in ;I)ecend)er Ms > 4 January then- are ^ li) clear days, and l)ut '.1 cloudy days, and in .luni' and Febnmry i 17 j 1 July there are -I and S clfar days, and Ki and 1-") cloudy day-.

The explanation of thes(> results is obvious; In winter, under n clear sky. radiation soon lowers the temperature, whereas a clear sky in sununer by pernuttinL;- greater insolation, will increase the temperature. In cloudy weather in wintir, radiation is stopped, and with an atmosphere nearly or (pnte saturated with moistiu'c the temiK-rature nnist rise ; in summer insolation is pre\euted, and consecpumt'y the temperature will remain lower than its normal \ alue.
