and that they are ineft'eftual where there is no ^ChyJe 
in the Blood to be detained. 
But to explain how Opiats do contribute to retain 
the Chyle and other Crudities in the Blood, longer 
than ufual, would require a Difquifition too tedious 
for this Place : But their Power of retarding or fup- 
prelhng all or molt of the Secretions and Excretions ; 
their palling or obtunding the Appetite^^ their enabling 
one to fad long, and fupporting one in Journies and 
Labour for a long Time without Food (Eftedls well 
known to the furls and ^fiatkls in their Journies 
through Deferts,£f c.)thefe, I fay, and fome other known 
EffeSs of Opium, do very much favour this Opinion. 
Secondly, The Want of Pus in the Wound wp 
probably owing to a Want of Recruit of Chyle in 
the Blood ; and the Flabbinefs and Palenefs of its 
Lips, to a Shrinking of the Parts for want of daily 
Nourifhment. . 
Thirdly, The fraall Quantity of Urtne was pro- 
bably alfo owing to a Want of Recruit of Fluids fwm 
the Prim<e Vice : For thefe, in a healthy State, find 
their Way to the Urinary Pafages very foon. The 
flight Tinftute of Yellow, which it had, mult have 
been from the Bile fpilt in the ydhdomen, and filtrated 
through the Duplicature of the Peritoneum, and Bot- 
tom of the Bladder : For it could not be fuppofed to 
derive its Colour from the Blood, into which no Btle 
could now enter by the common Way. 
Fourthly, The Want of Sahva, and the filky Uri- 
nefsof the Tongue, feems to have been owing to the 
fame Caufe, a Want of Recruit of Fluids m the Blood, 
and a Lofs of fo much of them as fell into the Jib- 
domen.
