gular order I have mentioned, and that, after three days more, tlie 

 young within the eggs were perfectly formed. 



Thefe laft-named animalcules did not live above three or four 

 days, whence I conjectured that they died for want of food." 



I determined to give a drawing of one of thefe animalcules, with 

 the eggs adhering to its body, as nearly as the limner was able 

 to reprelent it ; for when I took one of thern out of the water, 

 none or a very few parts of it could be plainly diltinguiflicd, fo 

 that it was neceflaiy to make the drawing while it lay in the 

 water. 



Plate XIV. /^. 16, ABCDEFG, exhibits this animalcule, as 

 it lay Avith its back next the limner. The letters CHI and E K L 

 reprefent four horns with which the head was furniflied. 



At the letters B M and F N are to be i^een the eggs which the 

 animalcule, having brought forth, had placed on the outfide of its 

 body about this part. 



AO and GP, are the forked parts of the tail, which round about 

 their extremities, Ihewn at the letters O P, were each again fubdi- 

 vided into four parts, which might have been taken merely for 

 hairs ; but when accurately examined, and with a good magnifier, 

 then each of thefe parts (marked in the figure O Q and PR) ap- 

 peared to be covered with a great number of wonderfully minute 

 particles. 



When the animalcule lay in this pofition, or even with its belly 

 tov^^ards the limner, thofe limbs or organs Avith which it moves it- 

 felf in the water, could not be diftinguiflied. I, therefore, placed 

 it fo that its fide might come into view, and that thus the limner 

 might copy them to his beft in the drawing. 



Fig. 1 7, exhibits, at the letters abed, thofe organs or limbs, 

 each of which confifis of eight parts, though they could not all be, 

 here fliewn ; and each of thefe is compofed of various organs, part 

 of which may be feen at fg. IS, at the letters e and f. 



Tins animalcule did not ufe thefe limbs in the fame manner as
