160 ACTION OF STRYCHNIA ON THE ANIMAL ECONOMY. 
had extracted by a process of his own invention, we were 
enabled to make a comparative examination, and to transmit 
to him the results, which he included in his work. 
The nature of these tumours being still little known, as well 
as the relation of the proximate principles found in them by 
chemical analysis, we have thought that it would not be un- 
interesting to physicians and chemists to publish here the 
composition of two of these tumours, one of which was situated 
on the shoulder, and the other on the occiput of two persons 
treated by Dr. Legrand. 
The first of these concretions presented in its composition 
the union of a very large quantity of albuminoid matter with 
a soft, fatty matter, and a little cholesterine. 
The second was almost entirely formed of this last sub- 
stance, and gave to the matter contained in this tumour a very 
remarkable pearly and micaceous aspect. 
The following were the proportions of these various prin- 
ciples, as shown by analysis.

THE ACTION OE STRYCHNIA ON THE ANIMAL ECONOMY. 
Mr. Cochrane, writing to the Medical Times , says, “ some 
time ago I was induced to try how strychnia would act upon 
a kitten, a stout little animal ; the quantity I employed was 
small, less than half a grain, which I rubbed over its gums. 
The action of it upon the animal was very gradual, affecting 
first the head, producing a sort of tottering walk, followed 
with slight tetanic indications, which went on increasing in 
severity, till they became very violent, causing in all the 
extremities the utmost extension, with extreme rigidity. In 
connection with the case, what surprised me much was the
