dant materials for exchange. In 1823 my identification of the 

 previously supposed white augite of Goshen with the species 

 spodumene, gave me confidence in the study of minerals, while 

 it increased my stock of specimens desirable to mineralogists. 

 The exchange I then carried on with the Austrian consul-general, 

 Baron von Lederer, in behalf of his own collection and that of 

 the Imperial Cabinet of Vienna, rapidly enriched my little 

 museum in foreign minerals. Indeed, from the first it was 

 sufficiently ample, to serve a useful purpose in the instruction of 

 beginners ; and was the sole resource of Prof. Amos Eaton in the 

 lectures he gave during two seasons before the students of the 

 institution. 



" On leaving college I resided a year partly in Cambridge and 

 partly in Boston, during which period I profited much in extend- 

 ing my collections, through visits to new localities in eastern 

 Massachusetts and Rhode Island, and still more by exchanges 

 with Prof. Nuttall and other active cultivators of mineralogy in 

 the region. I soon after made a very successful tour into Maine, 

 where, at Paris, I was the fortunate discoverer of the most re- 

 markable green and red tourmalines then known. With some 

 of these I made profitable exchanges with the British Museum 

 and other large collections. My association in 1828 with Prof. 

 Silliman as his assistant, and afterward with the college as a 

 lecturer on natural science for many years, afforded me unusual 

 facilities for the extension of my cabinet. All the best localities 

 of Connecticut were frequently visited, specimens of rare interest 

 secured, and the means of supplying scientific correspondents 

 abundantly obtained. These objects were still further effected by 

 journeys into adjoining States and the Canadas, until 1835, when 

 I became Professor of Chemistry in the Medical College of the 

 State of South Carolina, where a new and very ample field was 

 opened for the extension of my collections. From that time to 

 the present [1871], with the exception of the period of the civil 

 war, I have passed nearly the half of each year in the South, and 

 been engaged to a considerable extent in scientific and min- 

 ing explorations, which have resulted in varied and rich contri- 

 butions to my cabinet. These travels have also embraced the 

 Western or Mississippi States, attended by similar results. But 

 most of all have I gained by frequent excursions to the Old 

 World, having since 1839 twelve times visited Europe, where my 

 exchanges and purchases of specimens have been conducted on 

 a scale, I am led to believe, not surpassed by any of my country- 

 men. Numbers, however, have never been my aim in these acqui- 

 sitions. I have rather sought what was characteristic and instruc- 

 tive not, however, to the neglect of the rare and beautiful/' 



The foregoing relates to the mineralogical part of Prof. Shep-
