if these favoring circumstances do not occur, there is no outbreak 
of the disease. 
Consequently the professional veterinarian, and others who 
are laboring with him for the welfare of the agricultural interests, 
should by every means in their power, not only encourage and 
enforce a thorough sanitary system in the management of farm 
animals, but warn the public of the danger to be apprehended 
from a neglect of these sanitary measures, and look themselves 
to such, with other preventatives, as the means of combating these

tinguished, prevent spontaneous combustion in the future, by 
avoiding the conditions under which it may be developed. 
A CASE OF MENINGOCELE. 
By M. E. Knowles, Student. 
A bay gelding, 18 years old, was brought to the college for 
dissection, upon which the above was found. 
Situated on the left of the median line; under the 
anterior portions of the great complexus and splenius muscles. 
Attached by a pedicle, to the superior face of the atlas; imme¬ 
diately over and surrounding a pseudo-foramen, the axis of which 
was slightly towards the left of the median line. 
Its anterior limit was the anterior border of the atlas; pos¬ 
teriorly it was limited by the posterior border of the axis. 
Limited internally by the funicular portion of the ligamentum 
nuchae, internally overlapping the greater portion of the great 
oblique muscle of the head. 
In its growth it had displaced the great and small posterior 
straight muscles, and fibres of these were found covering the ex¬ 
ternal and superior faces of the cyst. 
Through the medium of areolar tissue it was quite intimately 
attached to the adjacent tissues. 
Extirpated, and placed upon the table, it is found to be rather
