The PREFACE. vii 



Sir Ifaac Newton, ivho ^ivas an Honour to the Britifti 

 Nation. 



This ^wonderfully furprh:irtg Genius made fuch 

 Difco-veries^ by the Help of geometrical Reafonings 

 on Matters of Fa<^, as mujl be an eternal Monument 

 of Honour to his Memory ; and if People ivould only 

 ginje themfelves Liberty to think, and not be carried 

 aiAJoy by outnvard Appearances, I quefion not but in 

 a Jhort Time n/je Jhould difconjer fomething as remark- 

 able in our Little World, as that illuftrious Author 

 has done in the Great. 



1 hanje purpofely omitted a feparate and diJiinSl 

 Difcourfe upon the Anatomy of a Horfe, that being 

 done to my Hand fo^jjell by Mr. Snape, and Mr. Gib- 

 fon ; therefore I hwve only taken Occafion no<w and 

 then to fpeak fomething of Comparati*ve Anatomy, 

 niohen I am t^-eating of the Difeafes of the Liver, 

 Lungs, ScZ. 'which <nxill eafly lead ayty judicious 

 Reader (as near as pojjtble) info ivhat nve term the 

 Etiology of Dijiempers. 



I muft like^ife inform the Reader, that I had the 

 Offer of number lefs Receipts (as they are ternid) 

 from fenjeral Gentlemen, that I might infert them 

 in this Book ; but I ha^e not in the leaf made ufe of 

 any of them, feeing he njoho has his Head full of 

 Receipts, has his Head full of Nonfenfe, by reafon 

 there is not an-^ fuch Thing as praStifng by Re- 

 ceipts, and a Nutnber of them only fer<ve to perplex 

 and confound the Reader ; therefore I ha've not err'd 

 in this Particular, althd" I hope I hanje fet donion 

 nvhat is neceffary for the Cure of each Dijlemper in 

 Horfe s. 



As to any farther Particulars, I muf refer to 

 the follovjing Difcourfe, and Jhall only here take 

 Notice in gejieral, that as all poffihle Breijity has 

 been Jludied on the 07ie Hand, fo I hanje not omitted 

 any Thing neceffary to be knonjjn by thofe nxjho de^ 

 fire to lend a helping Hand in the Cure of Dif- 

 eafes
