 been carried off. The use of food answers this purpose. 

 Almost all the inferior animals have particular substances 

 on which they feed exclusively. Some are herbivorous, 

 some are granivorous, and others-!, again, are carnivo- 

 rous. 



From various experiments, we have the following re- 

 sult:

BREAD MADE FROM THE MIXTURES OF VARIOUS 

 GRAINS. 



Cakes may be made of potatoe flour, without mixing with 

 any other, as follows : Its adhesive quality does not ad-

 flour ; but it may be managed in this manner. A small

 frying-pan ; this frame is grooved, and so constructed 

 that, by means of a presser or lid introduced into the 

 groove, the cake is at once fashioned according to the 

 dimensions of the mould. The frame containing the fari-
