EXTRAORDINARY GESTATION IN A MARE. 
I might now turn my attention to the books published since 
the year 1838, as w'ell as the veterinary articles which have found 
their way yito the different transactions of learned societies, French 
and foreign ; transactions of which some limited account is to be 
found in the library catalogue of M. Huzard, among the series of 
works of the kind on veterinary matters. And some faint idea 
may be formed of their probable number, when we come to be 
informed that J. D. Reuss has devoted 80 pages, of small pica, 
solely to the enumeration of the titles of veterinary articles met 
with in the memoirs of learned societies published up to 1821. 
From which date the number has become strangely augmented, 
since in no former time has veterinary literature been so assidu- 
ously cultivated either in France or other countries. 
As for the works published since 1838, their number must be 
very great. I could easily give the number of the French, but 
not of the foreign, of which but the principal are known to me. 
Among them, French and foreign too, are to be found a great num- 
ber of periodicals in continual issue, and transactions of learned 
medical, agricultural, and veterinary societies, which are also 
continuous. 
It would be very desirable to complete the list contained in 
Huzard’s library catalogue, which most probably contains a pretty 
full account of all the works published before 1838. I have already 
commenced this task, and am only waiting for documents I have 
asked of foreigners to complete it. 
Veterinary medicine was not so poor twenty years ago as repre- 
sented. To those holding such an opinion, it is a sufficient answer 
to remind them of the dates of the different works published prior 
to that period. 
CURIOUS CASE OF EXTRAORDINARY GESTATION 
IN A MARE. 
By M. Caillier. 
In May 1834, M. Caillier had committed to his care a seven- 
year-old mare, that for some years had been given up for breeding, 
and who in the May preceding had been covered by a stallion ass. 
At the time M. Caillier was called in, he found the mare’s ab- 
domen very large and sunken, appetite gone, surface of the body 
extremely cold, coat dull and harsh, membranes pallid, head in 
continual agitation, frequent yawnings, looking back often at flank, 
with sinking and approximation of the hind extremities, and 
unsteady painful step in walking, the foetus exhibiting no sign 
of life.
