EXTRACTS FROM EXCHANGES. 
PROTRACTED GESTATION. 
By Robert W. Ellis, D.V.S., New York City. 
u Hannah Panis,” the property of Bingham Brothers, of 
Westchester Comity, N. Y., was u bred ” to a standard horse on 
June 3d and 4th, 1895, and became pregnant at that time; the 
owner having positive knowledge that copulation was never re¬ 
peated after those dates, although parturition did not follow un¬ 
til September 1st, 1896, after a period of four hundred and fifty- 
five days, or four days less than fourteen months, when a 
splendidly formed male colt was delivered, seeming quite happy 
to be released from his bondage, where he had served seventy- 
five days over his time of sentence, or two and one-half months. 
If some of the practitioners from the breeding districts who 
have opportunities of making observations daily in this line are 
able to cite some cases that have departed so far from the nor¬ 
mal period of gestation, or anything approaching this case, I 
shall feel gratified if they will do so, through the columns of 
' the Review, as to me it is very unusual.

ENGLISH REVIEW. 
Strongyeus Tetracanthus. —In the Veterinary Record 
Mr. W. Pauer, M.R.C.V.S., records a case where, by the history 
of previous death by tuberculosis in her mate, a hackney mare 
was supposed to be suffering with the same affection, in taking 
into consideration the symptoms that she had presented. Turned 
out to grass as being unthrifty, she had fair appetite, never re¬ 
fusing a feed of corn and was almost constantly grazing. Day 
by day she wasted away until she was so emaciated that she 
could not stand up. Her excretions were normal, the visible 
mucous membranes pallid. Pulse normal in number but weak. 
Temperature ioo° F. Nothing abnormal on auscultation. She 
never passed parasites. She was destroyed, and, instead of tuber¬ 
culous lesions, which were looked for, she was found in perfect 
health, except that in the colon and caecum thousands of stron- 
gylus tetracanthus were found. Tuberculin was not known 
then, and of course the animal could not be put under its test. 
Period of Incubation of Rabies in Dog [By IV. H. 
Williamson , JRR.C.V.S .].—This article relates to two cases 
which came under the observation of the author. One, a toy 
spaniel, was shown to him with symptoms of rabies. Only a few
