IMPROVED. 87 



dently explain, when I come to treat of the Diftem- 

 per called the Grcafe in Horfes. 



Laftly ; Rovvelling may be of Service, as much 

 as any Thing, in obftinate Chronick Cafes, where 

 the Brain has for a long Time been affeded : But it 

 is not one fmgle Rowel which I advife, for that 

 will only make an inlignificant Difcharge, no more 

 in Comparifon to the Quantity of Blood, and other 

 Humours in a Horfe's Body, than a Drop of Water 

 compared to half a Pint. No, let me have five or 

 fix Rowels in the moil proper Parts, and continued 

 for fome coniiderable Time, if the Horfe can bear 

 the Lofs of what is difcharged by fuch Methods, 

 and then indeed fome Benefit may accrue from 

 them : Though this is no more than Revulfion, or 

 diverting the offending Humours to fome other Place-' 

 for Expulfion ; or rather, driving them into the 

 Mafs of Blood, and equally mi.^ng it. And that 

 Nature Ls better able to deal with the offending Par- 

 ticles, when equally mixed with the Mafs of Blood, 

 than when fuch Humoui-s are lodged upon fome 

 particular Part, is every Day vifible. And it is 

 for this Reafon, 'viz. that where the Particles 

 of Matter, which are of a Heterogeneous Nature 

 and confequently occafion Difeafes, are equally 

 mixed with the Mafs of Blood ; ( as indeed they 

 moftly are in the Origin or Beginning of Diflem- 

 pers, 'till Nature fuecumbs and is overpowered, 

 when they are thrown upon fome particular Part of 

 the Body, whereby the fmall Capillary Vefiels are 

 diftended, and form a Tumour, which at laft fup- 

 purates or breaks to let out the Enemy ; ) I iay^ 

 when they are fo mixed, all the Emun6k)ries or Se- 

 cretory Glands, jointly and feverally lend a helping 

 Hand, and each of them affift in carrying off a little 

 of the offending Humour. But, on the contrary, 

 if thefe offending Particles of Matter, happen to 

 lodge or be driven upon any particular Part, the 

 Glands are fo Huffed, and their Excretory Veffels 

 become fo brulhed up, that (as I juft now obferved) 



a Tumour
