CONTAGIOUS CHARACTER OF GLANDERS. 587 
than that of the matter of glanders, and that, consequently, the 
danger of communication is in that proportion lessened. Does 
not, however, the fourth experiment prove that it is possible to 
produce the disease by inoculation ? and that, if more effectual 
means are adopted to introduce the virus into the system, we 
might, by inoculating with the matter of strangles, when the 
weather and the state of the animal were propitious, avoid many 
serious accidents that now occur, and especially when the dis- 
ease appears in winter? 
Then, is it absolutely necessary to separate horses with stran- 
gles from sound ones? [ should say, only when the disease 
assumes a malignant form, and threatens to degenerate into 
glanders. Perhaps it would be useful to place the colts in whom 
the symptoms of strangles had great difficulty in developing 
themselves with others in whom it was more easily running its 
course; possibly it might more readily take on its proper cha- 
racter, unless it was preferred to inoculate those who were doin« - 
badly with matter obtained from the others. 
It would, however, be certainly imprudent to leave together, 
either in the stable or at pasture, colts of all ages, lest strangles 
should be communicated to some before the time nature had 
fixed for the ordinary development of it, and before they Were 
strong enough to struggle with it. 
As to the infection of the stables in which horses with strangles 
have been kept, it is right to be cleanly and to be safe ; but it 
appears that the danger is infinitely smaller than with glanders. 
The racks and the mangers and the buckets should, however, be 
well cleaned, and then there could not possibly be any danger. 
If strangles had in any of the cases degenerated into glanders, 
every precaution should be taken. The virus of strangles is one 
of a specific nature, and of which the air is not a vehicle any 
more than it is of glanders. It oftenest develops itself sponta- 
neously ; but it may assume different characters, more or less 
mild or virulent, according to the state of the animal, its tempe- 
rament or food, or according to the climate and the vicissitude of 
the seasons. 
Strangles, like other acute diseases, may take on the character, 
of the usual maladies of the season. When the wind is in the 
north, and the situation is elevated, it may, like the small-pox in 
the human being, assume an inflammatory character ; but in 
other states of the atmosphere, and in other seasons and locali- 
ties, it may be marked by a typhoid tendency. Strangles 
has been described by various authors as sometimes mild, and at 
other times malignant or gangrenous. In these circumstances, 
the disinfection of the stables and their furniture would be as
