the Scientific School, and gave him a position in the chemi- 

 cal laboratory. There lie at once became so useful to Silli- 

 inan. Jr., in making a series of water analyses as to earn a 

 salary, and ere long gain admission to the professor's house- 

 hold. His lirst paper to Silliman's Journal, u A Description 

 and Analysis of a New Mineral Species containing Titanium, 

 with Some Kemarks on the Constitution of Tellurium Min- 

 erals,' 1 is dated from Yale chemical laboratory in Februarv. 

 1846, and exhibits the same care in noting every step of the 

 analysis and every resulting reaction as characterized his 

 laboratory work throughout life. 



He wrote to a friend from Yale college laboratory, Xew 

 Haven, June 25, 1845 : 



" 1 have seated myself in the laboratory with the Masks 



bv my side, so as to work and write at the same time. 1 am 



jed in the analysis of corals collected by the U. S. 



dition, and now being analyzed for Government. Thev 



ilnmst pure carbonate of lime, with a few thousandths oi 



phosphoric acid and ammonia, and occasionally alumina. 



imen which had been sent as a coral mud or sand, i 



lund to be white arsenic, probably put up by mistake on 



:-d the ship 'I am generally occupied .ne or two 



hours eae'n day in assisting the i Sillimain in arran- 



drawings and specimens lor the lecture. I have 

 access to the cabinet, and a key to unlock all tli< 

 . . . . I am boarding in a club of students at Sl.'Jo a week. 

 We have little .r no meat. I do not like this very well, but 

 it is cheaper, though 1 think 1 will hoard myself alter a 

 while. Tin; room 1 i to have had been occupied, as 



it was uncertain whether 1 was comiiiL. 1 , and so 1 have taken 

 up lodgings in tin- loft. <>f the laboratory building itself, and
