In the firft Glafs Tube, in which were thofe Animal - 
cnla which I had (hut up the whole Winter, and were 
turn’d into flying Creatures, I obferv’d two young Ani- 
malcula running about, whofe Skins are defcribed by Fig. 
3. but how many of them there were I could not dif- 
cover, becaufe about a Month before I had put into 
the Tube the Tail of a Pole-Cat, to the end that they 
might fubflft on the Fur, which I was told they ufed to

Elefh of a Whale into the fame Tube. 
Thefe Young Animalcula were but little bigger than 
the Eggs before-mention’d. 
Since that time, I faw the faid Animalcula but once*

Flelh of a Whale into it 5 and I perceived that, after a 
few Hours, it had aflumed a rofle Colour. I alfo found 
three Eggs, in one of which the Animalculum was fo 
large, that by the help of a Microfcope, I could difco- 
ver part of the Body through the Shell of the Egg: 
And two Days after, being the 8th of June, I could 
perceive through a Microfcope, upon the wreathed or 
knotched Parts, red Streaks, upon which were long 
Hairs * and in the Evening the Animalculum was got out 
of the Egg-fhell, and the next Morning it had aflumed 
a rofle Colour. 
Upon the 13th of June, I faw fome few Eggs upon 
the Glafs * upon which I took two out, and put them 
into a Glafs Tube of the length and breadth of a Finger,
