4. When the ftomach and inteftines are thus 

 filled with their proper food, not only the motions 

 of the gaftric glands, the pancreas, liver, and 

 lacteal veflels, are excited into a&ion ; but at the 

 fame time the whole tribe of irritative motions are 

 exerted with greater energy, a greater degree of 

 warmth, colour, plumpnefs, and moiflure, is given 

 to the ikin from the increafed action of thofe glands 

 called capillary veifels ; pleafurable fenfation is ex- 

 cited, the voluntary motions are lefs eafily exerted, 

 and at length fufpended ; and fleep fucceeds, un- 

 lefs it be prevented by the fHmulus of furrounding 

 objects, or by voluntary exertion, or by an acqui- 

 red habit, which was originally produced by one or 

 other of thefe circufnftances, as is explained in Seel.

At this time alfo, as the blood-veflels become re- 

 plete with chyle, more urine is feparated into the 

 bladder, and lefs of it is reabforbed ; more mucus 

 poured into the cellular membranes, and lefs of it 

 jeabforbed : the pulfe becomes fuller and fofter, 

 and in general quicker. The reafon why lefs urine 

 and cellular mucus is abforbed after a full meal 

 with fufficient drink is owing to the blood-veflels 

 being fuller : hence one means to promote abforp- 

 tion is to decreafe the refiftance by emptying the 

 yeffels by venefedion. From this decreafed abforp- 

 tion the urine becomes pale as well as copious, and 

 the. ikin appears plump as well as florid. 



By daily repetition of thefe movements they all 

 become connected together, and make a diurnal 

 circle of irritative action, and if one of this chain 

 be difturbed, the whole is liable to be put into dif- 

 order. See Seft. XX. on Vertigo.
