the Symptoms he did enumerate before, necedarily at- 
tend this interruption of Perfpiration and that this 
Hypothefis of an interrupted Perfpiration may not be . 
begg'd,and ask'dG/*^/i,hedemonftrates, that an Inter- 
ruption of Perrpii;aticn can, and adually does produce 
this Effeft more than any thing elfe . The next ftep he 
makes, is to Intermitting Fevers; and when he has gi- 
ven an exadt Hiftory of all the Symptoms, and in that 
order they appear, he demonftrates the neceflary Pro- 
duftionof all thefe Symptoms, how every I^ermitting 
Fever has its beginning very fbon after Dinner, (^c. He 
demonftrates the neceffity of its returning in a certain 
time, and why that People that die of that Difeafe, muft 
always die in the cold Fit, and in the Return. After 
the fame manner he accounts for Diarrhaas and Dyfen- 
Uries ; and all other Sicknefles befides thefe, he calls 
the Interloping SicknefTes ot the Sea. Having ended 
thefe Stationary Sicknefles, he makes an Apology, or 
rather gives a Reafon why he did not take any help from 
the Chymical Principles ^ from Acid or Alkali, and the 
notion of Poifon, for accounting for his Difeafts, and fd\ 
ends the firft Part. 
In the fecond, he brings into our Memory, what he 
had faid about the nature of Continu'd Fevers ; and 
next giving us a Hiftory how Fevers end without the 
help of a Phyfician he gives us an account of the Pra- 
ftices of Phyficians then making Indications for the 
Cure from the Demonftration of the firft Part, he fet- 
tles the moft Genuine and Natural way of Curing a Fe- 
ver, and gives us fome Inftances of his own Practice. 
The lame Method he perfiies in Intermitting Fevers, 
where he has a pretty Effay about the Jefuits Powder, 
which he maintains to be the beft Medicine for that Dil- 
eafe : he (hows us the Advantages of Vomiting, and 
then proves that no body has accounted for the way bow
