receive 400 horses provided by the same depot, and that shall be 
one of the unfortunate regiments. Heavy losses shall fall upon 
these remount horses. The same horses, however, instead of going 
to this regiment, shall join one of the favoured class. The mortality 
among them now will amount to comparatively but little. 
In estimating the mortality among horses according to age, we 
find the fewest deaths among nine-year-old horses, viz. 51 per 
1000. Among those thirteen years old and upwards, 54 per 1000. 
The maximum of deaths occurred at six years of age, viz. 83 per 
1000. Next to these come horses of eight years old, 77 per 1000. 
In the other ages the mortality has fluctuated between 60 and 67 
per 1000. We have endeavoured in vain to shew cause for the 
surprising difference between the mortality of the eighth and ninth 
years, two periods seemingly so alike. 
In the remount depots, while glanders and farcy have proved less 
frequent, pneumonies and pleurisies have occurred in greater num- 
ber, and been more fatal. The number of recoveries have, it is 
true, risen ; but were these complete recoveries, and did the attacks 
of disease not leave behind them in the lungs and pleura marks of 
their former existence ! 
The first consideration in the health of a troop horse destined 
for quick movement is the integrity of his thoracic viscera. Slight 
lesion in these organs may prove of little consequence to a horse 
doing slow work, while it is apt to prove serious to one compelled 
to trot or to gallop. It is by no means uncommon to discover at 
the autopsies of horses that have died of glanders or diseases of 
the chest, old lesions in the lungs, lesions which, if they were not 
the occasion of these last and fatal attacks, have, at least, compli- 
cated them. And so we must be permitted to think, that a great 
number of horses, recovered of thoracic attacks at the remount 
depot, have brought with them into regiments the forms of disease 
under which they have eventually succumbed. If such probability 
were rendered a certainty, we could understand how necessary it 
would be to cast from the remount depots on account of diseases 
of the respiratory passages. 
The admissions into the infirmaries at the depots have been 
many more during the first than the second half year. Out of 5622
