S. "IZrAVE now been on the ninrket for several years, l)otli in Canada anil elsewhere, and in every case have given perfect satisfaction, thus fnllillinfi" the many chiinis made for them of superiority over all others. They have been improved from time to time. l)otli in style and linish as wi-ll as workinu', until tile presi'ut styles, as illustrated hei'ewith, were inoduced. whicli are about as near perfection as it is possible to make them. The principal advantage in the "Unique" lies in the 'I'ransmitter. which is the oidy one nuide that can never get out of adjustuient oi" lUst up. and is not alVected by sudden changes of temperature. Jarring, etc. It has no screw or spring adjustment to work loose; the adjustment is all done at the factory, and every instrunu'ut is thoroughly tested before l)cing sent out. anil unless wrong- fully used, should never need any attention beyond replenishing the l»atteiy about once a year at a cost of a few cents. Another advantage is that the same transmitter is suited for either long or short distances without cluinge of adjust- ment, which is necessary in other makes in order to get the best results. These are all very strong i)oints in its favor, as the transmittei- is the vital part of a telephone, and with one that does not require attention a great saving is nnule in its maintenance, to say nothing of the convenience and lack of annoyance Avhich tlie vast nuijority of telephone users will readily understand. Tlie '' Unique " Transmitter is composed of Carbon Phites and IJalls, placed in a nntnner peculiarly sensitive in the conveyance of sound. A mouth- l)iece is used in order that tlie sound of the voice may be concentrated, and so be brought more forcibly on the diaphragm. The "Unique" Telephones are carefully made by experienced workmen, and handsomely gotten up. Every instrument is thoroughly tested and inspected before leaving the factory. Special silk-covered wire is used through- out in all the coils, which are carefully wound to a standard resistance, and measured before being used. Particular attention is paid to the Switches, which are very strong and have si)lendid make and break connections, and good rubbing contacts which keep same always bright and clean, thus ensuring good connections. All connections are soldered Avith special salts, and every detail of their manufacture is most carefully worked out. The Receivers have a highly polished hard rubber shell, and are ((// titled with compound magnets of specially imported and tempered steel, ^^^th nickle tip to prevent rusting, and are strong and loud. The Receiver Cords are the best made, with patent tips and attachments to relieve the strain from connections. The woodwork i,s of the best seasoned cherry, linished in the natural wood and polished, not stained. All the trimm- ings are nickle plated, which with the light, i)olished cherry, nudvc a very handsome linish. Every part is made for constant use and guaranteed to be as represented. < 3 Wo Iinvo iiltorod n unni1)(>r of ollior inakof.' of ToloplioiioH by pulling' on llip "• rni(|iio" 'rr:insniitU'rs iiiid Hcccivt'is which ii.ivi' fircally iinpmvod tlic sorviv sonic of iho Icstinioninis hon^willi.

We nd U|) lliese TcleplKuies in liv»' ditTerenl slyles. as follows : IVo. 1. — Willi Kledric Hells, for short distances and inside use; very useful for connecting' the different tlooi's in a luiildiug. in place of speaking-tidies, being much more convenient, and are j>laced in position without injury to walls and Mooring, as in the case of speaking-tubes. This style is designed expressly for aft'ordiug commun- icalioii ill Factories, Warehouses, IIoIcIh, Houses, elc. !^c>. 1 yV. — 'I'hese are goltt'ii up for Warehouse pur- poses — same as our Xo. 1 — Ittil have iJattci'v IJox attiiclied, and are more complete. Tliey have also a Swjii'h board atta( hod, as shown, so the different deparl- inenls or Hats in a biiihling, as many as wanted, can be connected in one system, and by simply plugging the desired number, communication can l)e at once procured with the instru- ment wanted. We use a Split IMug Switch as it is much more reliable and convenient than llie Har switch. Only the bell on the instrument with which communication is desired is rimu'. thus avoiding the iieccssily of signals and consecpient misunderstanding. .More than two persons can use the svstem at one time without interfering wilh one another: thus in a system of six instruments, nunihers I and 4, 2 and (!, o and '> can converse at the <\mo time, or when two are talking a third can be rung up and the three converse tooether. This is a verv sinii)le arrangement, and its great convenience can be readily understoos. The niajj;- netoes are wound throughout Avith silk covered wire, and have extra strong generators, with patent cut-out. We use a special long bar Hoceiver Switch of our own invention, which is ffitironi/Jilii rch'ithh', and and simple, (this is a most important point,) and has splendid rubbing contacts and "ground" connections. The Receivers have a handsomely polished, hard rubber shell, and heavily compounded magnets made of a si)ecial imported and tempered steel, Avith nickel tip to prevent rust. AVe have no hesitation in claiming this to bo tiie handsomest and best Telephone in existence for eitlier excliange or private use on long or short lines. .\'o. ». IVo. 4.— Portable or Desk Tele- phono. Tliese are handsomely gotten up with he.ivy nickel base and polished case, and can be used in connection with eitlior of our other styles. It is the most portable Telephone made. A tlex- ible silk covered cord is provided with each, as shown, by which means the in- strument can be moved al)out at will, thus avoiding the necessity of leaving one's sent to answer a call. The silk cord tormiuates in a nicely finished wall rosette and connoeted to binding posts 'thereon to which are connected the main line and battery- wires, this is screwed to the wall, giving a very neat api)ear- ance. IJy the addition of a few extra batteries, the central oflice can be called 4 \o. *.

'I'iic only additional cost for lliirt in the extra itat- tcncH, and if thoHC arc not wanted, no chanjic is needed in the telephone. The battery supplied with the telephone is sulllcient for rinination switch, the Desk 'IVlephone can be switched on to either the main or warehouse circuit. This is very convenient, as a subsbriber can sit at his desk and converse with any part of his warehouse or connect with the oxchau«>e.
