— Ordinarily, the bite of a Dog, such as the playful bite of 
— painful, carries no danger with it, but if the animal has only been 
-a. wion this malady its bite is but too frequently fatal. This death-dealing influence has 
been proved to remain in the saliva for four-and-twenty hours after the animal’s death. Per- 
haps there may be something of electricity in the fatal influence, which requires a fluid con- 
ductor, for if the teeth of the animal have been wiped dry by passing through the clothing of 
its intended victim no evil results follow. 
Hot every one that is bitten by a rabid Dog is a sufferer from Hydrophobia, for it is need- 
ful that the constitution should be in a fit state to receive the poison, for its influence to pro- 
duce any effect. We may notice a similar phenomenon among those who are vaccinated. 
Some persons appear to be almost proof against the vaccine virus, while others feel its effects 
so powerfully that they are thrown into a temporary fever, and the limb on which the vaccina- 
tion is performed, swells to such a degree as to be extremely painful to the patient, and some- 
times even alarming to the operator. In others, again, no visible effect is produced until they 
have undergone the operation two or three times, and then the disease develops itself fully 
and with great rapidity. 
A rather remarkable circumstance connected with this subject took place within the last 
few years. A rabid Dog contrived to bite a large number of victims, including other Dogs, 
sheep, oxen, and human beings ; a surgeon attended the human sufferers, and treated the 
wounds by the severe application of nitrate of silver. All were treated in the same manner, 
but although the greater number escaped without further injury, several died from Hydropho- 
bia ; and all those in whom the disease made itself manifest were light-haired persons, while 
those who escaped had dark hair. 
The mode of treatment in such dire necessity is fortunately very simple, and can be 
applied by any one who is possessed of sufficient nerve and presence of mind. A piece of nitrate 
of silver, or lunar caustic, as it is popularly called, should be cut to a point like a common
