like a law ; and I alfo law the claws or pincers ot a young crab, 

 which had been no largei- than a grain of land. 



The Itomachs of others were filled with fragments of fmall bones 

 from the fpine of minute lillies, appearing like the back bones and 

 tails of haddocks. I like wife law a fmall bone of a lliape and make 

 diflerent from any I had ever before feen in fillies. 



■ 1 alfo faw in the llomachs of many Shrimps, but not in equal 

 quantities in all, fmall fliells, in fliape fimilar to thofe llaells which 

 are found in the greatell quantities on our coall:s, nor did I find 

 many fragments of fuch fhells, whence I concluded that, about the 

 beginning of September (for it was about that time thefe obferva- 

 tions were entered upon) many of the fmall flicU-filli, newly pro- 

 duced from the parent, had been caught by the Shrimps, and their 

 fhells broken by their teeth, in order to pick out the young filhes 

 from the fliells and ufe them for food. 



Many of thefe minute fliells were no bigger than large grains of 

 fand, and I was moreover well alTured that all thofe fliells which I 

 took out of the llomachs of the Shrimps had been but a few days 

 brought forth by the parents, becaufe many of thofe fliells were 

 quite tranfparent, others of them were in part about their outer 

 edges rather obfcure, by reafon, as I imagined, that they had had 

 an addition in growth fince the filhes were brought forth. 



I caufed a drawing to be made of one of thefe minute fliells, but 

 which was one of the largell of thofe I had extradled ; and, at fg. 

 35, this fliell is fliewn of the fame fize as it appeared to the limner 

 by the naked eye. Fig. 36. P Q R S, is the fame fliell feen through 

 the microfcope : the letters P Q R T fliew that part of it which ap- 

 peared bright and tranfparent, fo that all without the letters PQRT 

 which was not tranfparent, was added to the fliell by growth, after 

 it was feparated from the parent. 



In fome of the Shrimps' llomachs I found fome exceeding minute 

 fliells, which, on account of their round figure, I called fnails, and 

 which were not larger than a large grain of fand ; and to fliew the
