4. That of the nephrite of Smithfield, R. I. and 



5. The examination of the magnetic effects of the Ca- 

 loiimotor of Dr. Hare, were all performed while he was a 

 pupil in the laboratory of Yale College.* 



After leaving that situation, he went through a regular 

 medical education in the University of Pennsylvania ; al- 

 ways however, retaining a most decided preference for his 

 favorite pursuits, and his wishes were crowned with com- 

 plete success by an early and honorable appointment, with, as 

 we have understood from him, an ample endowment of appa- 

 ratus and other means, and we have no doubt he would have 

 risen to distinguished eminence, if a mysterious Providence 

 had not cut him off at the early age of twenty eight. 



Died, at one o'clock in the morning of November 14, 

 Timothy Dvvight Eaton, son of Prof. Amos Eaton, and Ad- 

 junct Professor in Rensselaer School at Troy ; being about 

 21 years of age. He had devoted to the Natural Sciences 

 most of the few years allotted to him by Providence. He 

 had attended Prof. Silliman's lectures on Chemistry and 

 Mineralogy before he was nine years old, enough to catch 

 th.it spirit of enthusiasm for the study of Nature, which gov- 

 erned his future life. Under the immediate direction of his 

 father, he had collected, labelled, and preserved, more than 

 one thousand species of plants before he was ten years old. 

 His progress in Mineralogy, Geology, and Zoology, was 

 equally successful. Young as he was, he introduced many 

 improvements in facilitating the manipulations of the Labo- 

 ratory at the Rensselaer School ; where he will long be re- 

 membered for his inflexible integrity, industry, and discrim- 

 inatinij talents. 



The four last of these papers, are cantained in Vol. V. of this Journal.
