th" account of the dilFerent fituation of the channels and parts it 
paffes through. And here he makes fome kind of parallel between 
this Diftemper and Intermitting Feavers, from a few reafons, to be 
feen in the difcourfe itfelf 
Then he lays down the feveral adminiftrations, which he con- 
ceives it requifite to attejnpt the Cure by, annexing fach- reaibns of . 
-each as appear probable to him ; And though,, in the firft phjce, he. 
3 he has no great opinion of the vulgar Specifick^ ('-efpe- 
. , all due evacuations are premifed) and gives fom^ reafohs of 
the inefiicacy of the AncieiTt. Specificks in our Age, yet he quotes 
Jlr Bfy/e'fox the efficacy of one, vlzy i;ue Slifleioe of the Oak^ 
and lays dowil one Infiance of the good effefl of in, unon his own 
Exp€r.ience._ 
Then he confiders the ufe of Evacuating adminiliLiiions, as, firft, 
Phlebotomy-, then Fontanels, particularly a Seton ; afterwards 
Purgatives ^ where he endeavours brietly to jiiftlfie jD/- SyieSam'^. 
advice of giving Purgatives in Maniacal affefts xjpon precife' days^ 
then mentions, and only mentions here, Ihjenfih-le ^f erfpiration ^ 
fince he fubjoyus a difcourfe cpncerniftg' it at the end of this 
Letter, ' . , 
Then he proceeds to conlider feveral queftions and doubts, which 
Dr Hohdrfs Letter raifes or hints •, as firft, one Phoenomenon con- 
cerning the Patients Head growing firft hot in the beginning of the 
Paroxyfm, then a coldnels feizing him ^ in a contrary courfe to 
that of Intermitting Feavers : Then the ufe of Tobacco, Stale Beer, 
but more particularly Sweet fmells, which refrefht him ^ where he 
takes occafion to difcufs that queftion, whether Smelling be per- 
formed by an admiihon of the odorous particles into the olfaftory 
Nerves at their extremities, or only an im.prefiive on them-, and 
adds withal an attempt at a reafon, why fweet fniells may be agree- 
able to Epjleptkk perfons ( as in the prefent cafe ) but are apt to 
occafion Uyfleriek Fits, though the Symptom.s of both thefe diftem- 
pers leem to have a great aflinity . 
Having reply' d to the moft, material parts of the Letter,, he comes 
to give an account of the Matter and Manner of Infenfible Ferjpi' 
rauon. from an Hypothefis, ivhich h? believes to b>e wholly, new, 
and his -Own, as not having met with it either in any Author or . in 
difcourie. For rho' the celebrated SapMorim hath from thirty 
years obfervatiori demonftrated the or/ of it, without contradiftion 
from any," yet neither he, nor any fincCj having ( fo far as this 
Author has obferved) attempted to give a Rationale pf it, nor di- 
Itiriguifht the Mutter of /V, from that of Svocat^ on which diftitiftion
