the same. In the second class, the positive result of diagnosis 
is all that has been obtained, but no diminution or disappear¬ 
ance of the lameness, which always returns to stay after the 
effects of the injection have subsided. Neurotomy in those 
cases brought about a satisfactory result. 
This point established, Mr. Pecus continued his observations 
with the two alkaloids, and his general conclusions are: 
Cocaine or morphine, separated or associated, in solution, 
injected on the tract of sensitive nerves, removes for the time 
being the pain in the peripheric end of that nerve. Those in¬ 
jections can be used to establish a positive diagnosis of the loca¬ 
tion of painful parts in affections situated between the point of 
injection and the periphery. They are sometimes followed by 
an analgesy sufficiently long and complete to be considered as 
having a true therapeutic action. This curative effect, rare 
with cocaine alone, more frequent with morphine, is more read¬ 
ily obtained and for a longer duration with the cocaine and 
morphine mixture. Injections of morphine are as diagnostic as 
those of cocaine, but possess curative properties more certain.

an important point already treated by Dr. Debierre in his work 
on “ Heredite Normale et Pathologique,” where he puts the 
question : “ Is it true that a first child impregnates its mother 
to such an extent that the child of a second marriage will re¬ 
semble the first husband, dead a long time before?” Or, to 
widen the application, is it true that a thorough-bred female 
animal, covered by one of equal standing, would continue to 
give products resembling the first male when served by others 
of lower classes ? 
Much has been written upon this important question, and 
the controversy has been very active, advocates and non-partisans 
being unable to agree. And how could it be otherwise when 
the former were satisfied to take the exception for the rule and 
accept as undoubted evidence cases where ignored sexual con-
