THis Author ( for whom his {ormct Treati/es had 
prepared a welcom in the world) divides the Prac- 
tice t^f Fhyficj^into ordinary and extraordinary, the for- 
mer he looks upon to be <iefed:ive in thefetwo things; 
firft in fufEcient Experiments on which to ground a theo- 
tie , and fecoridly, in generous medicines as well univer- 
fal as fpecifick, which fhould have their efFecS without 
Nature's too hard labour, the former to be fupplied by 
Anatomy, the latter by Chy mi/try. In curing any difeaie 
he obferves thefe five heads, the hiftory of the diltemperj 
the part affe£ted, the caufes, prognoflicks , and me- 
thod of curing. He looks upon it to be of the greatefl 
confequence to diftinguifii between the Animal iaculty 
placed in the fpirits and Genus Nervofum s and the vital, 
whofefeat is in the blood, and Vi/cera. He allows in 
the blood two motions, the circulatory, and fermenta- 
tive, to this he (uppofes the concurrence of an Acid and 
an AI call, the foundation of which motion is that Semz^ 
nal crajisy which is preferved by a due ufe. of the res mon^ 
j^^^r^/^/, and reflored by proper medicines. 
In the Animal faculty he confiders its nourifliment, 
which is pyyle ; and its ftru<3:ure , the delicate Fibres of 
which are the inftruments of fenfe and motion, on both 
which Scores it is iubjedl to convulfive motions,, when ir- 
ritated; or Paralytical impotence when obftrucitgd. 
Thefe foundations being laid, he recommend s Sylvius, 
and Willis to the Reader, and gives the neceffary cau- 
tions for their Reading, looks upon Sennertus to he iuf- 
ficient among the Antients, as containing the fenfe of all
