large# of which contained a finall Quantity of a tran - 
/parent Fluid of a light yellowifh Colour, which on 
putting the Snake into Spirit of Wine changed to a 
beautiful Red (the Fangs of the common Vipers I 
have examined had the lower Perforation nearer the 
Middle) Freeing the Mouth of the Membrane, a Muf- 
cle appears about the Size of the fir# defcribed above, 
which arifes from the Middle of the Maxillarum c Di- 
latores ( Fig . 3. D.D.) and is inferted on the under 
Side of the larged Tooth, for the Force required to pull 
down the Fang being lefs than to raife it, fewer Muf-

Jicians ^ and of thefe the fird died about two Minutes after 
the Bite, and the Moment he was bit he grew convulfed,

College had tide fam£ Symptoms with the fird, but 
liv’d near a Quarter of an Hour, and had bloody Stools. 
Three Days after, I carried the Snake to bite another 
Dog and Cat. The Dog was larger than either of the 
two former, and having been bit at the Extremity of 
the Nofe he was immediately affe&ed, howled, fhook, 
fell down and foamed at the Mouth ; and in about 
ten Minutes difcharged his Excrements involuntarily, 
tinged with Blood : He died in about two Hours. The 
next Day I opened the Body arid obferv’d the Abdomi -
