328 THE MICROSCOPICAL NEWS. 
In forty-eight hours the cut parts were gradually healing upwards 
by the outer edges being drawn together. 
This was finally completed in three days and six hours, so that 
now I have two perfect bodies from the original Hydra upon one 
foot-stalk, each body having four tentacles. 
The next day I could discern on one of the bodies a slight 
swelling, which in four more days turned out to be a young bud; 
three processes showing themselves at this time. (Fig. 87 B.D.) 
The young Hydra was the first to partake of any food ; after 
this time the parent caught and devoured its prey, and both of the 
cut portions continued to bud freely. 
I find that it is perfectly true that Hydrz which have been 
divided grow much larger, and bud more freely than those not 
operated upon.

Experiment third. I cut a polype into two parts transversely, as 
close as possible to the part where the arms branch out, giving to 
the head part the appearance of a five-fingered star-fish. (Fig, 88.) 
In the centre the mouth could be very well defined, and it is in 
this state that its position and shape can be best made out. The 
mouth extends and is somewhat drawn into the arms. Upon 
placing it into fresh water in the glass, the head part lay upon the 
bottom for some time. The arms, by constantly contracting and 
expanding, gave evident signs of life. 
In twenty-four hours it had drawn the opening together, and 
had, at the same time, lengthened its body, although but slightly, 
giving it still more the appearance of a star-fish ; for it not only 
rested upon its arms, but moved from place to place by stretching 
them out and drawing its body forwards. In forty-eight hours it
