I. The Anatomy of the Poifonous Apparatus of a 
Rattle-Snake, made by the J)ire£lion of Sir Hans 
Sloane, Bart, Pnef. Soc. Reg. &c Coll. Med. 
Together with an Account of the quid ^ Ejfetts of 
its Toifon 5 by John Ranby, Efq : $ Surgeon to his 
Majeftys Houfbold, and K (Zy. S'. 
T H I S Animal was fent from Virginia to an 
eminent Merchant, and having been by him 
prefented to Sir Hans Sloane , it whs plac’d 
in my Hands, on Purpofe to make fuch Experiments 
with it as might inform Mankind of the fatal Sym- 
ptoms which attend its Bite, and the Appearances in 
the dead Bodies of fuch Animals as have been bit by 
it. It is only by this Method, and a Number of Fads 
faithfully dated and compared with each other, that 
we may hope one Time or other to difeover the Man- 
ner of the Poifon’s operating, and perhaps ( a thing of 
the utmoft Confequence) to find out fome Remedies, 
internal or external, to relieve Perfons bit by it. The 
Anatomy of the Rattle-Snake having been fo accurate-

more can be added to his Account ; I fhall therefore only 
take Notice of th 0 Inftruments of its Poifon, fome of 
which are different from what that celebrated Anato- 
mift obferv’d. Removing then the common Integu-
