THE ROYAL AND CENTRAL SOCIETY 
Their influence is not bounded here. They inculcate among 
their pupils the notions which their previous studies had sug- 
gested to themselves — they enable them to perceive all that is 
erroneous in certain routines, and in certain agricultural opera- 
tions — they place them on their guard against prejudices im- 
bibed in the country ; and their pupils, mingling with the agri- 
cultural population, in daily contact with them in the treatment 
of’ their cattle, are commencing on all these points the foundation 
of much that is good. 
The culture of artificial meadows, in furnishing abundant and 
healthy food for the cattle, has bestowed the means of rapid im- 
provement among them, and of preserving them, in a great 
measure at least, from the fearful maladies by which they were 
decimated. You know the rest: not only are the cattle, gene- 
rally speaking, more healthy, but their numbers and their size 
are increased. Every agricultural production is likewise increased 
and improved, and the prosperity and happiness of the community 
at large. 
At the present period we more particularly experience the 
benefits of veterinary medicine. The epizootics which formerly 
ravaged our fields, and bade defiance to our utmost skill, have 
their power to a great degree arrested when they are brought into 
contact with animals that are better fed and better housed. 
11. The last memoir is entitled “ Anatomical and Pathological 
Researches on Glanders. 
The author of this Essay has instituted a somewhat new and 
interesting and valuable method of detecting the existence and 
progress of glanders ; and he tells us that it is only by examining 
with the eye, and having the scalpel in hand, that we can dis- 
cover, to effectual purpose, the vessels of the diseased tissues, and 
thoroughly acquaint ourselves with the progress of their disorgani- 
zation. 
The following, according to him, is the usual order of the phe- 
nomena which accompany the external symptoms of glanders. 
Tumefaction of the diseased submucous tissue, but in many 
respects different from that of inflammation. 
Indurated longitudinal lines at the middle of the tumefaction. 
On being opened, these indurated lines permit us to ascertain 
that they are the lymphatic vessels already subject to these alte- 
rations. 
The lymph accumulates and distends them to a very great de- 
gree. 
In some points, the lymph is changed. It is partly coagu- 
lated, and it has produced a veritable precipitation of matter
