180 [ASSEJIBLY 



Mr. Fitz, Mr. Fisher Langstrclh, and Mr. Young, vv-ith one or two 

 other competent persons, had also made a comparison of the two 

 glasses on the 28th, and perfectly coincide with me in what I have 

 said. I called to see Mr. Langstrcth and one of the other gentlemen 

 this morning, and found they each had arrived at the same conclusion 

 as myself as regards the merits of Mr. Filz ; indeed, we are delighted 

 with his success, and I ana fully persuaded that between this and one 

 you order from Merz, the chances would be decidedly in favor of 

 the former. 



Very truly yours, 



E. OTIS KENDALL. 



In addition to this testimonial of the merit and success of Mr. Fitz, 

 we are permitted to insert the following extract from a letter written 

 by the Rev. James Curley, Professor of x\stronomy at Georgetown 

 College, dated Nov. 7, 1S49, addressed to Mr. Filz : 



** It is highly pleasing to hear of the extraordinary result of your 

 efforts in working achromatic glasses. I am much pleased that you 

 get enough to do, and I only regret now that it was not our lot to 

 have an instrument made by you instead of our equatorial made by 

 Slmms -of London. It cost me about $1500. I do not see much 

 advantage in the size of the circle over yours, but I see a great ad- 

 vantage in the glass of your last instrument being eight-tenths of an 

 inch larger than ours." 



Much credit is due to Lieut. Gibbs, in charge of the expedition 

 above alluded to, for the part he took in bringing forward the ability 

 of Mr. Fitz, who is a native of New-York, and self-taught in the aj-t 

 he has so successfully managed. 



The equatorial telescope exhibited at our twenty-second Annual 

 Fair, was made to order for Erskine College, Due West Corner, Ab- 

 beville district, S. C. The object glass is 5.6 inches aperture, 7 feet 

 focal length. It has 8 eye pieces, magnifying from 84 to 500 times ; 

 an achromatic finder 2 feet focus; nn hour circle 7^ inches diameter, 

 and a declination circle 9^ inches diameter. It is furnished with a 

 position and distance micrometer, and a clock fur moving the tele-
