Heredity of Glanders.— The participation of the offspring 
in the diseases of their parents, and the development in the 
former of the germs existing in the constitution of the progeni¬ 
tor, aie facts which cannot be ignored. But just to what extent 
md just in what proportion the idiosyncracies of the parents con¬ 
tribute, by transmission of germs or otherwise, to influence or 
iriginate the characteristics of the mutual product, remain, 
ivith kindred questions, yet to be explored. Contagious dis¬ 
eases a,re transmissible from the mother to the foetus by the pla- 
eenta, in many affections, and there can be no doubt that mi_ 
erobes carried by the blood have more chances to contaminate a 
[i.cetus than those which are enclosed in an organ in which they 
jnust meet many obstacles to their dispersion through the 
economy, by the character of the changes to which they cdve

Amongst the diseases whose maternal heredity is well known, 
>oth in man anti animals, are small-pox, measles, scarlet fever,' 
yphilis, chicken cholera, symptomatic anthrax, anthrax fever, 5 
)leuro-pneumonia, small-pox in sheep, and tuberculosis. 
The influence contributed by the male parent in the trans- 
j n ^ S8 * on °f contagious diseases is, however, more limited than 
hat of the mother, although syphilis in man and tuberculosis 
n animals are well known to be inherited by the offspring of 
>arents affected with those diseases. The extent to which these 
conditions influence the product of glanderous parents is a qnes- 
10n of great interest, and which Messrs. Cadeac and Malet, of 
! Toulouse veterinary schools, have endeavored to solve. By a 
umber of clinical observations, and a number of experiments, 
tiey have obtained the following facts: 
1st. Out of twenty-nine clinical observations, there is not 
ne which conclusively proves the transmission of glanders from 
!ie mother to the foetus.

2d. Out of twenty-one experiments, this transmission has 
een proved only four times. 
3d. Out of fifteen animals born of healthy mares and glan-
