in the Practice of Phyfick, and was never undertaken 
by any other. Among thofc Hiftones is one very re- 
markable of an Intermittent, which was partly occai% 
on'd by the Stone of the Kidneys ; and Three, of Pa- 
tients which he cur'd with his own Specific when the 
Cortex would not prevail, and in thefe Hiftories he is 
very punctual and exa£t, and fets down all the particu- 
lars that were any way material in this method of 
Cure. 
The Second Exercitation begins with a general Dif- 
courie of continued Fevers,' whofe Ferment is in a 
higher degree Venomous than the Ferment of the Intcr- 
mittents, and therefore the Spirits cannot caft it off" en- 
tirely at once, but are always in a Feverifti Commotion. 
If the Spirits in every ConfluSt gain ground of the Poy- 
fbn, tho never fb little, the Fever is a Remittent but 
when the Poyfbn is in the higheft degree venomous, the 
Spirits 'are federated in fome meafure from the very be- 
ginning, and the Fever thereby occafion'd is continual, 
without any remtffion and malignant, becaufe the Poy- 
fon is equal if not fuperiour to the Spirits. The Venom 
therefore of the(e Fevers differs only in degree, and Ma- 
lignant Fevers often~tim.es are changed into Remittent, 
and Remittent into Malignant : And it is very well 
worth Observation, that Epidemical Fevers, tho highly 
malignant, have a manifeft Remidion on the Third Day, 
fbmetimes alfb oh the Fifth and the Seventh and when 
they draw towards a good Crifis, and the Spirits begin 
to be expanded, remit again at (et times, Hence it is to 
be concluded, that a Remitting Fever is not fatal, unlefs 
it be accompany'd with fbme Symptomatical Inflamma- 
tion or Colliquation. How the Poyfon in the Remittent 
Fever comes to produce thefe Symptoms is here iliewed 
by the Author. Continued -Malignant Fevers'he referves
