ON RABIES. 
correct to say that such will be the character of these months in 
every year. Experience has demonstrated, and observation has 
convinced us, that it is at the beginning of the heat of summer, 
and towards its end, that the greatest number of rabid dogs are 
found in France. Climate has also some influence on the deve¬ 
lopment of rabies. It is very rare in the torrid zone; it has never 
been seen in Egypt, Syria, or Constantinople; and it also appears 
to be unknown within the polar circles. 
The long-continued privation of food or of drink can never 
occasion rabies. The experiments of Redi and of Bourgelat are 
positive on this point. We can say as much with regard to the 
non-gratification of the sexual appetite in these animals; and 
also the fits, rage, and fury, to which they occasionally abandon 
themselves, and to which they are disgracefully trained; and 
also the want of cutaneous transpiration in the dog. The causes 
of spontaneous rabies in the dog are altogether unknown. 
A. Distinction. We distinguish two kinds of rabies in the 
dog. The one which is contagious is the true rabies: the other, 
the contagion of which is yet doubtful, is dumb madness. It will 
be advantageous to establish some characters, although few in 
number, by which we can distinguish them from each other. 
THE TRUE RABIES OF THE DOG. 
Principal Symptoms. 
First day. — Commencement. 
Barking, or rather a kind of howl¬ 
ing, deep and hoarse ; heard princi¬ 
pally during the night, and occasion¬ 
ally in the day. 
Second and third days. — Increase 
and march of the disease. 
The eyes brilliant, wandering, and 
menacing, with desire to bite men 
and animals. Sometimes an ap¬ 
pearance along the fraenulum of the 
tongue of small vesicles, elongated 
or round, white, and inclosing a se¬ 
rous fluid (the supposed characteristic 
pustules of Marochetti). The animals 
seize and devour unnatural substances, 
such as hay, grass, earth. They have 
no dread of water—they are frightened 
at polished bodies—they cannot swal¬ 
low soft or liquid food—they are 
continually unquiet and moving about. 
There are fits of rage, during which 
THE FALSE OR DUMB MADNESS OF 
THE DOG. 
Principal Symptoms. 
First day. — Commencement. 
Barking, with a tone approaching 
to true rabies, but heard particularly 
when the animal is excited. The 
mouth is half open, and the saliva is 
abundant. 
Second and third days.—Increase 
and march of the disease. 
A stupid expression of countenance 
—no desire to bite—the dog is not 
anxious to eat or to drink—the jaws 
are permanently separated from each 
other. The buccal membrane is of a 
deep red—the pharynx and the veil 
of the palate are of a reddish brown. 
The patient is unable to bite either the 
animate or inanimate bodies around 
hinj, but he endeavours gently to 
grasp any object that attracts his 
attention. He cannot lap fluids. 
The countenance is always stupid; 
the attitudes express weariness or 
weakness, and the movements are
