One remarkable Particular in this Loufc is, that 
its little fibriilous Fins are always in Motion, whe-

ALL Fifh regulate their Times of Eating and Abfi 
tinence by the Temperature of the Air, and the

they are feparated they become melancholy and fal- 
len, and are a long time before they forget the Lofs. 
About Chrijlmas laft I put two Ruffs into a Jar 
of Water, where they lived together until Aprils 
when, at the Defire of a Friend, I gave one of them 
away*
