1. THE throat, ftomach, and inteftines, may be confidered as 

 one great gland ; which like the lachrymal fack above mentioned, 

 neither begins nor ends in the circulation. Though the adl of 

 mafticating our aliment belongs to the fenfitive clafs of motions, 

 for the pleafure of its tafte induces the mufcles of the jaw into 

 a6Uon ; yet the deglutition of it when mafticated is generally, 

 if not always, an irritative motion, occafioned by the application 

 of the food already mafticated to the origin of the pharinx ; in 

 the fame manner as we often fwallow our fpittle without attendi- 

 ing to it. 



The ruminating clafs of animals have the power to invert the 

 motion of their gullet, and of their firft ftomach, from the ftim- 

 ulus of this aliment, when it is a little further prepared ; as is 

 their daily practice in chewing the cud : and appears to the eye 

 of any one, who attends to them, whilft they are employed iu 

 this fecond maftication of their food. 



2. When our natural aliment arrives into the ftomach, this or- 

 gan is ftimulated into its proper vermicular action ; which be- 

 ginning at the upper orifice of it, and terminating at the lower 

 one, gradually mixes together and pufhes forwards the digefting 

 materials into the inteftine beneath it. 



At the fame time the glands, that fupply the gaftric juices, 

 which are neceflary to promote the chemical part of the procefs
