Michel and Bachraan's observations were by no means so 

 complete, since they did not actually see what transpired, 

 but only inferred what the method of removal was from 

 what was noticed before and after the transfer. 



Dr. Charles T. Jackson exhibited specimens of Ceanothiis 

 americam/s, or Jersey Tea, recently announced by some 

 speculators as the Chinese Tea-plant, growing on the old red 

 sandstone districts of Pennsylvania ; and also a copy of the 

 charter of the American Tea Company. 



Dr. Charles Pickering stated that he had recently found 

 Juncus trijidus, an arctic and alpine plant, growing upon the 

 top of Mount Monadnock, whose height had been given at 

 3,600 feet ; while the upper limit of trees on the White 

 Mountains was seldom if ever lower than 3,900 or 4,000 feet. 

 He explained their living at so much less an altitude by the 

 fact that the upper portion of Mount Monadnock is so rocky 

 as not to allow of the growth of trees upon it, for want of suf- 

 ficient soil, rendering the summit much less sheltered than 

 similar wooded elevations would be. 



Dr. Gray remarked, that the discovery of so peculiarly an 

 arctic plant upon Mount Monadnock was quite unexpected. 

 Grandfather Mountain, in North Carolina, of very much 

 greater elevation (5,897 feet), was wooded to the summit, or 

 with the exception of a very small peak, where only the alpine 

 plants grew. Willoughby Mountain, near the Canada line, 

 was much lower than Monadnock, but nourished quite a gar- 

 den of subaljDine plants. Dr. G-ray thought that the only 

 valid explanation of their presence was that which referred 

 their origin to a time previous to the glacial epoch ; these 

 little patches being left in the only spots which still preserved 

 an arctic character in their climate. 



Mr. A. S. Bickmore exhibited to the Society a specimen of 

 Am2:)hioxus (Lancelet), which he had collected on Bird Shoal, 

 a sand-bank off Beaufort, N.C, March 9, 1862, while digging 

 for Jjinffula pyra7nidata during a very low spring tide. 



The specimen was found in the sand, two or three inches below the 

 surface ; and was so active, that It escaped once, and was with difficulty 

 captured a second time. Its color was milk-white, and the animal was
