NEWS AND SUNDRIES. 
Introducing the Pasteur System.— Dr. D. E. Salmon, D. 
V.M., lias for several years devoted much time and experiment to 
the study in which Pasteur has deservedly achieved so high a rep¬ 
utation the world over—the prevention or amelioration of conta¬ 
gious diseases among live stock, by inoculating sound animals with 
a form of the virus of the disease, that will prevent a fatal attack 
subsequently, without endangering life from the mild attack pro¬ 
duced by the inoculation. The method adopted by Dr. Salmon 
for lessening the virulence of the virus so as to fit it for inoculat¬ 
ing, or rather vaccinating, purposes, differs considerably from the 
“attenuating” system of Pasteur, and we are glad to learn that 
the Doctor is to have an opportunity of thoroughly testing its 
efficiency. He has been summoned to Washington by Commis¬ 
sioner Loring, and is about to inaugurate a series of experiments 
in his method for the Department of Agriculture .—Rural New

The Results of Section of the Vagus upon Sheep.— Ellen- 
Sc 
berger has made some very interesting experiments to determine 
the effect of section of the pneumogastrics upon sheep. He found 
that after cutting the pneumogastric on one side only, no disturb¬ 
ance of heart, lungs, or stomach was observed. The general mat¬ 
ter was not impaired. Ten weeks after the section the animals 
were killed. There appeared to be some thinning and atrophy of 
the muscular wall of the third and fourth stomach in the animal 
whose right vagus was cut, and a similar change in the first and 
second stomach of the animal whose left vagus was cut. When 
both vagi were cut the animals died in from twelve to twenty-six 
hours, except in one case, when life was prolonged for sixteen 
days. Death resulted in all cases from suffocation by stopping of 
air-passages There was constantly observed: complete paralysis 
of the oesophagus, partial paralysis of the first and second stom¬ 
achs, increased heart-beat up to 160 per minute, labored irregular 
and at first slower (12 to 16 per minute) respiration, and inability 
to regurgitate and chew the cud. It appears that the vagus sends 
motor nerve-fibres to the first and second stomachs, but that the 
third’and fourth stomachs are enervate independently. The con-
