Munich price, $500. If inferior, we should have the right 
to retain and use it, free of cost, until another could be im- 
ported from Bavaria.. 
“ Between the date of the order, November 27th, and the 
time that the tube was ready, April 15, 1849, Mr. Fitz pre- 
pared three lenses of that size. Veins developed themselves 
in one, only after it had been polished ; and a second proved 
scarcely less objectionable in its crystallization. Of the third 
submitted for trial, Professor Kendall wrote to me, May 1: 
‘I had the pleasure of making trial of the Fitz object-glass 
last evening, and was highly gratified with the result. I 
compared it with ours upon the moon, Jupiter, several 
double stars, and the bright star Vega, with its companion, 
using a variety of powers, and it is my opinion that Mr. 
Fitz has fully accomplished all that he undertook to per- 
orm. From this trial I am unable to pronounce which is 
the better glass.) The Fraunhofer did nothing which was 
not as well done by the Fitz glass... . . Indeed, we are 
all delighted with his success, and I am fully persuaded that 
between this and one you might order from Merz the 
chances would be decidedly in favor of the former, 
“ Gratification is a feeble word to express my pleasure at 
the success of the American optician, for I could not but 
think this first Yankee telescope of considerable size marked - 
an era in the progress of mechanical science in our country, 
for which I hoped future astronomers would render due 
credit to the expedition. That Mr. Fitz was thoroughly 
competent to figure and polish, I was fully convinced, on ex- 
amining the object-glasses previously made, and my only 
_ -Fregret was that he could not forthwith undertake the whole

had genius, and nothing would be more likely to stimulate
