INCREASE OF CASES OF GLANDERS. 
There are some reasons to fear that glanders is again 
becoming very rife among the horses in the country and in 
our large towns in particular. Several cases have recently 
come under our observation, and according to report some 
of the chief mercantile establishments in the metropolis 
are sustaining heavy losses from this disease. The knackers’ 
yards are beginning to tell the same tale, with an irresistible 
truth, which they told some two or three months since. Too 
often the spread of this malignant disease, as well as its 
serious outbreak in an acute form among the horses of large 
firms, are found to depend on keeping an animal in the 
stables which is supposed to be merely the subject of chronic 
nasal gleet; often to an extent which in no way interferes 
with his usefulness. 
CANCER OF THE SALIVARY GLANDS AND 
TONGUE OF A COW. 
Mil. Cooper, of Chatteris, has forwarded to us an in¬ 
teresting specimen of cancer of the parotid and submaxillary 
glands and tongue of a cow. The case was brought under 
his notice a few weeks since, and, contrary to his advice, the 
animal was permitted to live on ; a hope being entertained by 
her owuier that benefit would result from treatment. 
A singular circumstance is mentioned by Mr. Cooper, 
namely, that in nine cases which have been brought under 
his notice, three “ have occurred on one piece of land, 
within a mile and a half of Chatteris.” He offers no explana¬ 
tion of this fact, which, if not depending upon hereditary 
causes, is one that requires a full investigation. The study 
of local influences in the production of diseases, hitherto 
regarded as special, whether affecting man or brute, has not 
received that amount of attention which its importance 
calls for. Let us hope that we are on the eve of a better 
state of things, and that men of science will combine in 
investigations of this kind. Even the practical agriculturist 
could render important service in all such inquiries.
