C.T. & N.J. Chester's new catalogue

C. T. & J. N. Chester's Illustrated Catalogue.

WE are in receipt of the fifth edition of Messrs. C. T. & J. N. CHESTER's Illustrated Catalogue of Telegraphic Instruments and Material. This little book has been successively revised and enlarged until it has almost attained the dignity of a treatise upon the subject. In glancing over its pages, the most casual observer cannot fail to be struck with the great number and variety of the different articles manufactured by this well known firm, many of which they were the first to introduce to the Telegraphers of America. Among the novelties described and illustrated in this edition we notice a pocket magnet of entirely new construction - a perfect beauty - which must be seen to be appreciated. A new style of sounders, brought out within the past year, has met with a very favorable reception among operators. There is nothing particularly new in the way of keys, if we except the well known "CATON," with tumbler circuit closer, which is rapidly superseding the old patterns. The BROOKS Insulator and BUNNELL Repeater are shown, both of which are well known to our readers. Batteries seem to be a specialty - we might almost say a hobby - of the Messrs. CHESTER, therefore we are not surprised to find two or three decided novelties in this line. The air-tight battery, giving the intensity of 100 GROVE cups in a cubic foot of space, and which was recently illustrated in the columns of THE TELEGRAPHER, challenges the admiration of all electricians. For the laboratory or testing room it is unrivalled. A sulphate of copper battery, arranged upon the principle of MIEDINGER, for long continued action, is also shown, which we predict will yet become a general favorite in this country for main circuits. Space forbids us to detail the innumerable other articles embraced in the list, comprising everything required in the construction, maintenance and working of Telegraph lines. This catalogue will be forwarded, on application, to parties wishing to purchase articles in this line.
