I am desirous, however, of an inspection of nients, and a comparison with those of any first-olass American makers. isits and Theodolites I would direct more especial atten- I believe they will bo found superior to any produced D this continent, and more completo and better in many those usually sold by the best London makers. The 9 and other philosophical instruments will also bo found ' the attention of parties e|ngagcd in scientific pursuits ; pply them on more advantageous terms than they can u from any European miker of established reputation, ibr years past been my constant aim to improve in lish and e£Gciency the different kinds of instrumenta ■cd by me ; as a proof of my success, I may state that I awarded the first prizes at the Provincial Exhibitions 859, 1860, and 1861, every time I have competed. D seen that many of my prices are reduced — in most I English standard — but this will not be followed by ion in the quality, as I employ none but skilful and workmen, and every Instrument is personally exam- roved, and will not be sent out if likely to injure my as a maker.
