we have not done so, we have, nevertheless, expressed our 
opinion; and should it not agree with that of others, it is 
only bearing out the adage that “ opinions differ;” while we 
have no desire to be dogmatical, the onus probandi not resting 
with us. 
We will only add that Dr. Christison has found the 
Indian Hemp (Cannabis sativa) to be both more energetic 
and more certain in its action than the ergot of rye as an 
a<jent for increasing; the force of the uterine contractions. 
The form of tincture, or a watery solution of the extract, 
is preferred by him. 
Our Indian friends could aid us here in obtaining this 
agent in its purity, and, perhaps, tell us somewhat more of 
its effects on the lower animals. 
ON ENTOZOA. 
By G. Boddington, M.R.C.V.S., Canton, Cardiff. 
Since the commencement of my professional duties here, 
up to the present time, I have been called upon almost 
without intermission to prescribe for horses suffering from 
" worms ” and on examination I have invariably found the 
report to be true ; the Ascaris lumbricdides existing in such 
numbers, in almost all cases, as never, during the whole 
of my experience, do I remember to have seen. Indeed, 
hitherto in those cases that have come under my notice these 
parasites have not been of that nature, nor their consequences 
of that character, as to lead me to think seriously of their 
presence, or that any injury would be likely to accrue from

appearance in summer, been naturally voided, and then 
nothing more heard of them. 
Such, however, has been the urgency of the symptoms 
presented in many of the cases upon w 7 hich I have been 
consulted, that I consider them fully entitled to due notice, 
and also requiring prompt attention. I find that all the 
symptoms it is possible for the horse to exhibit of Inver- 
mination are usually present, and in order to justify this 
opinion I shall record one or two of the numerous cases 
that have occurred, all of which I am happy to say have been 
most successfully treated by me. 
Case No. 1 was a blood, bay mare, five years old, the 
property of Capt. E. B—ke, which I w r as called in to see on
