SYNOPSIS OF CONTINENTAL VETERINARY JOURNALS. 7 
tered, a quantity often reduced to a minimum by amputation 
after a short time of the part in which the virus had been 
deposited. Finally, these presumed anti-virulent agents 
have not even appreciably diminished the contagion-bearing 
power after a great number of successive transmissions or 
of virulent generations. Charbonaceous blood taken from the 
first animal operated upon affected the second, and blood 
from that a third. In the series of experiments, extending 
over a month, fifty experimental cases of production of virus 
were utilised; four were treated with hyposulphite of soda, 
six with iodine, the others by sulphate of quinine or carbolic 
acid. The charbon was not destroyed ; its power underwent 
no sensible diminution at each of its transmissions ; it always 
destroyed as rapidly as if it had originated naturally or had 
appeared spontaneously. At the end it had all the severity 
it manifested at the commencement of the experiments; thus, 
after the fiftieth generation, it caused death at the end of 
twenty-four hours.” 
M. Bouley , while admitting the value of these experi¬ 
ments, considers them as by no means thoroughly applicable 
to the human subject; considering the liability of the system 
of the rabbit to septic infection, no time is allowed for 
the action of remedial agents. But in man the time of 
incubation during which the system contends against the 
septic invasion enables, or may enable, antiseptics to produce 
anti-virulent effects. 
Dr. Krisaber communicated, at the meeting of 29th 
October of the Academy of Medicine, a “ New Method of 
performing Tracheotomy in the Horse,” which he terms 
Subcricoid Tracheotomy. He claims for it the following 
beneficial effects :—It gives an artificial passage for air to 
supplement that gained through the natural passages when 
such are obstructed. The ascending branch of the tube used 
serves to separate the vocal cords, and so to give the glottis 
dimensions by which it may freely subserve respiration. 
Another benefit urged is that an animal wearing such a 
tube permanently might be freely used, since the tube, being 
high up, would not be so conspicuous as the ordinary tube. 
The operation may be readily performed. The crico-tracheal 
depresssion may be easily distinguished beneath the skin, 
and exposed by simple incision through the integument. 
But, M. Bouley asks, would not the up-and-down movements 
of the head result in the friction of the branches of the tra¬ 
cheotomy tube against the lining of the trachea, leading to 
inflammation and sphacelus ? And we would ask whether 
the sensitiveness of the upper part of the larynx would allow
