i^S ANIMALCULA OF iNFUSIONS. IJ 



During this the branches of the fhrub had fo 

 ranch extended, and become enlarged, that the 

 circumference was triple. But the fupervening 

 death of the animalcula occafioned that of the 

 plant : They began to fall from the branches as 

 fruit falls from the tree; and as they gradually 

 feparated, the motive faculty was deflroyed. Spour 

 taneous extenfion and contraction were no longer 

 feen- the vibration of the hbrilli at the mouth of 

 ihe bell, nor the confequent vortex. Every fign 

 of animation was gone ; each animalcule became 

 mifhapen, and was deftroyed. l"he tree lived 

 vyhile it had animalcula ; after that it neither liv- 

 ed nor vegetated ; there was not the leaft indica- 

 tion of fpontaneous motion. Such was the fate 

 of half the fpot which I had taken from the 

 niarfh lentil root and put in a watchrglafs. 



I could now fee the generation of thefe animal 

 ilirubs. Although the animalcula often died 

 where they were produced and vegetated, that is, 



at 



nition is, Vortlcella compofita inverfc conica peJur.culo 

 rajnofo. The other is defined ; Vorticella fimplex cam- 

 panulata pedunculo retortili. It is not in my power to 

 decide -whether they are really different or not. The de- 

 fcription of all thefe complicated animals will be much 

 better underflood by confulting the figures in Mullet'^ 

 work, PJate 44. 45 46. — T.
