which characterizes many yellow fever cases I do not find de- 
scribed as a current symptom of the venom malady, but it is 
often mentioned as one of the accompaniments of the period 
of the recovery from the bite.* It is, indeed, most probable 
that if small and repeated doses of venom were introduced at 
intervals into the body of an animal, a disease might be pro- 
duced even more resembling the malady in question. 
“Tn the parallel thus drawn I have given the broad out- 
lines of resemblance, nor was it to be expected that the minor 
details would be alike. From a general and philosophic 
point of view, this similarity is sufficiently striking to make 
me hope that the complete control of one septic poison for ex- 
perimental use may enable us in future to throw new light on 
those septic poisons of disease, of whose composition we know 
nothing, and whose very means of entering the body they 
destroy is as yet a mystery.” 
Pathogenetic tables, showing the effects of the different 
poisons upon the system when taken into the stomach, are as 
yet quite incomplete, and for this reason only synopses of some 
of them are given. It is the Author’s intention to collect all 
reliable data together, and thus make this study more com- 
plete, so that what any one desires to know of every branch 
of this subject may be found in another edition of the present 
work. 
* Jaundice, occasionally observed in France, as an early symptom of 
viper-bite, has been usually regarded as jaundice of fear ; 2 cause which 
certainly cannot be invoked to account for the icterus seen in the last 
stages of the malady caused by the venom.
