THe Learned Author cfthis Boo^ makes it his chief bufinefs thereinj to vindicate 
his Doftrine , which maketh the two AfFeftionsjCicpreficd in the Title > to belong 
to the Bruin and the Nerves , from the Arguments alledged by the other Learned Phy- 
fiiian Dr Highmorei who makes the one to be a diftempcrof the Bloud and Lungs, and 
the other of the Stomach. In the doing ofwhich , our Author j?r/? undertakes to frcwi 
by fevcral confidewblc Arguments, that the afieftions, caiied Hyiiericd , cannot proceed 
from the Lungs fluffed up to a great degree of fliffncfs wuh flatulent Bloud 5 Icconding 
them by fome Hiftories and Obfervationj , which Cecm very pertinent to his purpcfc : 
Which done , he proceeds to rcttiove the difficulties and Objections , alledged by Dr 
Highmere in his Epiftle,foxmerly primed > and taken notice oT in N. 54« of ihcfc Tranf- 
aftions. ^ 
Secondly^ he endeavors to evince 1 that the Hyfechondriacli paflion is vrrorgfully afcri- 
bed to the Stomach, Where he taketh occafion » both to deny to the Spleen the office of 
Warming the Stomachj^n^f to affert the Fermentative funClion of the fame: Teaching 
withal, tbat the Acidity is not produced in theflomach alone, nor thence, only communi- 
cated to the Bloud and other humors j and that it proceeds from the fiuor of the Salt , 
antfthatthat Sah is one of the Elements of Natural things; which latter he attempts to 
make out by Experiments againfl the Objeftions of his Adverfary. 
To this Vindication are annexe tvjo ExercitaiionSi whereof the Firfl is concerned in 
proving the -^tce/i^OJJ 0/ the Bloud: Where the v^mhor undertakes to fhew , that the 
Bloud being animate, that i4nimationor Life depends from its being kindled , fcrafmucb 
as the proper affcdions of Fire and Flame belong to the Life of the Bloud S which is 
here deduced at large ; although it be wiihal acknowledgedjtbat this Vital Flame doih nor, 
as the common Flamcjappear to view, in regard that its Form is fubordinate to another fu- 
pf rior form, x;/:(, the corporeal Soul of the v^^nimal. 
The [tcond Difcourfe treateth of the Mufcakr M^tion^ where, having df clared,that 
Dr Steno hath been the firfl that hath delivered aright the Strufture of Mufdcs, and that 
the IFigures defcribcd by him are vifible in them y and alfo made out the motions of their 
Fibers by divers ^^natomical Experiments 5 befides many other confiderable particulars : 
He affertSjtbat the Motion of Mufdes depends from a confhnt InfluXjboch of the Bloud and 
theyfnimal fpiritsj and that the latter alone, Jwithout bcin{ affociatcd by the former, 
cannot perform that moving fundion 5 maintaining , that the Spirits ( or 
Sprii3gy particles ) m the contradion of a Mufde rufh out of the Tendons into the Flefl jr 
parts of ic, and in the relaxation,skip back frcm thefe into thofe, fo thofe Spir itSj'yjng quiet 
within the Tendons, dofwellchc Flefhy fibres byconflifting and flrugling therewith tit 
particles of Bloud. To v/hkh he adds the manncr,ho\v the InRinft fas Ke plea:erh to call 
it ) of.performing or flopping the Mufcular Motion J is imprinted by the Ne. v.s in the 
Mufcles : $ub^{o|rning alfo divers important' particulars concerning two forts of Sj. afmcs 
or Convulfjons proceeding from the Mufcles, with an ilbflration of the fame by a ve y re- 
markable cafe. M\ which he concludeth vsiih folving the O bje ft icns,to which this his Do- 
iftrincof the >/ulcles may belyable, and annexing fome Figures 5 very lively reprc- 
ting foinc Mufcles , together with an hxpiication ot the fame,
