226 ANIMALCULA OF INFUSIONS. 1* 



« tice. Plants and animals, therefore, are only 

 ^ modifications of organized matter : all partici- 



' pate 



* Plants lofe part of their organs during winter : ftill 



* they hve and are preparing to refunie their original 



* ftate in fpring. This cannot be compared to the fleep 

 ' of marmots, for in their organs, there is no apparent 



* alteration. 



^ Berthollet has properly charadterifed animal and vege- 



* table fubflances by (hewing that the cauftic alkali, which 



* diflblves the former, does not aft on the latter ; and that 



* animal fubftances, with nitrous acid, gave out much 



* azote, which, in diftillation, produced ammoniac, by 

 « combining with the hydrogen of water : while vegetables 



* aflorded an acid by diftillation, and an ardent fpirit by 



* fermentation, which has no refemblance to ammoniac. 



« The fingular work of Girod Ckantram is known to me 



* only by an extrad. ' Like him, I had obferved the gio- 

 « bules of certain confervae of different fpherical figures, 

 « but I found no animality. Thefe refearches were finifhed 



* long ago. I communicated them to my friend Spallan- 



* zaniy and requcfted him to repeat fome of my obferva- 

 « tions. Ke did fo ; but he cculd difcover no kind of ant- 

 « mation in thefe plants. The chemical analyfis by Tingrf 



* of the Conferva Bullofa, and rny own of the green fubftance 

 « forming in veflels of water expofed to light, produced' 



* nothing more relative to animality than the analyfis of 

 « other plants. Even admitting the animality of thefe. 



* Cryptogamia, I cannot fee how it would prove that 



* of other vegetables. Senebier Phyfiologis Vegetale^toni. 5. p.
