168 Of the frejJo Water Pofype. 
Fie only looked upon the motion of thefe two parts, 
as figns of the weak remains of life, efpecially with re- 
Ipedt to the hinder part, and therefore obferved it only 
to know how long it would remain alive, not in the lead: 
hoping to be the fpecfator of this fo marvellous a re¬

But obferving the cut pieces on the ninth day with a 
magnifying glafs, perceived three little points coming 
out from the edges of the anterior end of the feCond part, 
which had neither head nor arms. The next day he was 
convinced they were arms, and the day following two 
new arms came out, and fome days after three more ;

the known functions of ftretching themfelves out, con¬ 
tracting and walking. 
After this he difcovered one in a great glafs he had by

In the month of April he found a new fort of polypes,

tom of ditches, and are fufpended upon the furface of 
tfie water, upon branches of trees, boards, rotten leaves,
