I. ANIMALCULA OF INFUSIONS. I47 



Having left the plant thus in the glafs, I ex^ 

 amined it next day; all was in thq fame flate, 

 except that inftead of one animalcule as before, 

 proceeding from the extremity of each branch, 

 there were two, Plate i. fig. 7. K. And thofe 

 yet fmgle were marked with a very fine furrow, 

 L. The novelty attrafted my attention ; and it 

 was foon perceptible that the furrow indicated 

 an incipient divifion ; each in a fliort time be- 

 came double. Then I began to underftand how 

 fo many animalcula appeared double on. one pe- 

 dicle; it was a propagation from divifioir. I can- 

 not fay whether the origin of the branches, to 

 which they are attached, feparate in the fame 

 manner ; my obfervations on that fubjed: have 

 not been fufficient ; but the animalcula were in 

 pairs, and thofe at firfl almofl in contaft, in 

 half a day, were far afunder, and had attained 

 their complete fize, K. L. fig, 7. plate i. Fur- 

 ther, I can affirm, that from each old branch two 

 new ones budded; and the reproduced animals 

 were implanted on their fummit, K. Thefe at- 

 tained the neceifary fize, divided as the parent, 

 and remained to terminate new branches or 

 twigs ; whence the multiplication of branches 

 •was in proportion to that of animalcula, and both 

 continued multiplying many days(i}.
