Signer Redh Letter „ that he is uiueh more confirmed in if. 
The Controverrie confifts chiefly in this : i . That Signer J^r^i 
willhavethe Jellow liquor contain'd in the bags of the Teeth- 
gum of Vipers ro be the only and true feat of their Venom. 
2. That this liquor is indeed not Venomous being taken at the 
mouth, biit only wheaiet into a wound ^ made cither by rheliv« 
Animal, or even by a dead ones teeth , thruft iat6 ones flefli after 
k is dead; , ThcCt the lame Juice drawn from a dead Viper , as 
#ell as frdii^live one , is alwaies veriom^ous , if it pafs into a 
wound and mingle with the bloud of the wounded Animal , v\ he- 
iher it be liquid, or dried to powder. 4, That it kills genei al'y , 
all forts of Animals being wounded, and receiving of this liquor 
Into the wound. Whereas M. Char^^ alTerts , i . That the Venom 
of Vipers is only in the enraged Spirits. 2. That tiie jellow li- 
quor, as well of a live and even a much ajigred Viper , asof a 
dead one, hath no Venom at all in it , neither in the biting, nor 
when taken inwardly , nor let into a wound and mixt with the 
blOud, norany other way; and confequently that it kills and 
infects no kinds of AhimaJs , but is a pure and very innocent 
Saliva*. 
To make good thefe afTertions, M. Chartg^.zfliTms to have made 
new EKperiments , in the prefence of two or three hundred per- 
fons,PhyiicSans and others,capable to Judge,and of great veracity; 
and to have found abundant caufe to adhere to the refult , he had 
made frotn fii$ former tryals, That never any oncAninial of 
all thofe y he wounded ^ died of the jellow liquor let into the 
wounds,, thqughdrawnhotfrom the bags of the gums of Vipers 
much enraged. Thefe Experiments are at length defcribcd in his 
looki * 
If it be faid in favour of Signor Redi, that tie diverfity of 
Climats, or of food alfo ^ may change the nature of Vipers , and 
caufcthat manifeftdifferencfe between the Experiments; M.Char 
roi aafwers,thkt it ca1:inot be,lhat the nature the Jellow liquor, 
liKi that of the Spirits liiould be fp quite changed ; becaufe, that 
in Frame the fame marks are found in the Jellow Hquor with thofc 
idefcipibed of Itafyy and that the French Vipers do , without an 
intei^ventionof the Paid liquor> kill as readily ^ as thofe of Italy 
can do- And he adds, that he hath verified it by very many 
Experiments^ That all the Vipers of France, though taken in very
