which induces the dog to perish with hunger, rather than for¬ 
sake the grave that encloses the remains of him he once loved. 
Neither kind nor cruel treatment can force him from his retreat; 
and one idea alone occupies his mind, until he sinks under the 
mingled influence of famine and grief.

to time and experience to give a satisfactory answer.

Is chronic glanders contagious ? This is a question on which 
much has been written, but to which no satisfactory answer has 
yet been given. Some veterinary surgeons have affirmed that it 
is contagious, others have maintained a totally opposite opinion, 
and a great number are yet in doubt. This is one of those ques¬ 
tions that cannot be resolved by any reasoning or eloquence, nor 
even by isolated facts. If glanders is contagious, it ought to 
obey the general law by which all affections of this nature are 
governed ; it ought to be transmitted to sound animals, either 
by inoculating them with the matter which is supposed to be the 
virus, or the vehicle of the virus, of glRnders, or by making them 
cohabit with animals that are infected. Avery few facts would* 
be decisive here ; two or three cases well authenticated would 
convince the most incredulous, and range the whole world under 
the same banner. How is it that these experiments have not 
hitherto been made, or at least that they have only been made 
on animals enfeebled by age, work, or disease, and in which the 
development of glanders after the inoculation might be as reason¬ 
ably attributed to this state of debility as to the inoculation? 
The reason is plain. In order that the experiments should be 
conclusive, it is necessary that the subjects on which they are 
made, should be young, strong, and in perfect health : but sub-
