EXTRACTS FROM FOREIGN JOURNALS. 
1st. That the specific agent of tuberculosis acts in the same 
manner as the ovce of strongyli, and carries its initial action upon 
blood vessels in which it circulates. 
2d. That the tubercular follicle is nothing else but a nodulous 
vascularity. _ . 
3d That it has no anatomical specificity. 
In a further communication I will present a certain number 
of facts to establish the mode of development, and the sigmfica-

A CASE OF MATERNAL AND FCETAL DISTOCIA. 
By Mr. L. Blanchard. 
The patient, a cow, was in labor twenty-four hours when the 
gentleman was called. She had already been treated by empirics 
and the delivery seemed to bo impossible. A vaginal examination 
revealed first a contracted os, which was found protruding in le 
vagina as an ovoid mass, rugous on its surface and giving a fibrous 
sensation to the touch. The opening of the neck is turned down¬ 
wards, and allows with difficulty the introduction of the fingers. 
After using the means recommended in similar cases, sue 1 as 
belladonna, vaginal douches, &c.,&c.,the division of the neck was 
made by the introduction of a blunt bistoury into it and a 
double incision to the right and left of the median me was 
made. Entrance to the uterus being thus obtained, the ban 
detected the two fore feet of the foetus, but the head was found 
twisted back over the left shoulder, its inferior face being turned 
upwards With a hook, the head, after many manipulations, was 
brought in good position, but as by the exertions required the 
symphisis of the lower jaw was about to be divided, the hook was 
then secured on the vomer, and the head being proper y se¬ 
cured, the calf was extracted, not without difficulty. At first 
the little subject seemed to be dead, but by artificial respiration 
he was revived. He was carefully cleaned, and an hour later was 
sucking its mother. The cow also made a good recovery .—Jour-
