yij Glajfe^ proper for PolypeSo^ 



End of a Quill , to which it xtvy readily ad- 

 heres. It is ple;ifant enough to obferve then! 

 in fuch a Veffel, hanging from its Sides, or 

 erefting themfelves at the Bottom, all ex- 

 tending their An ns at the fame time^ and fo 

 occupying every Place, that as foon as a 

 Worm is thrown in, three or four of them, 

 perhaps lay hold of it. This faves the Trou- 

 ble of feeding eacih particularly, as in the 

 fmaller Glafles; for here I only fling in 

 Worms, and let them take their Chance: 

 but then it has this Difadvantage, that all 

 of them are not conrtantly fed, nor any of 

 them fo often as in the fmaller GlafTes; which 

 prevents their growing large. And therefore 

 I ftill keep a few (as well as all under Experi- 

 ment) in my little Glaffes, where I feed them 

 as often as they like to eat, and by fo doing 

 have fome whofe Bodies are very near- 

 three Inches in Length, when they extend 

 themfelves; which, if I may guefs by what I 

 have feen of Mr. Trembley's Obfervati- 

 ons, is longer than any of his, that are kept 

 in very large Veffels : and perhaps much lon- 

 ger than they would ever grow even in their 

 own Waters. Thefe very large Polypes fel- 

 dom fatten to the Sides of the Veflfel, or raife 

 themfelves much from the Bottom 3 but ly^ 

 along there, opprefled as it were with their 

 own Bignefs, and extending their Arms but 

 little. Their Form is alfo commonly irre- 

 gular. The largcft I have it^n have beea
