The fever was confined to those who occupied the houses and huts which I have described.

All the brigade suffered much, but my regiment, then the first battalion of the 12th Regiment, and now the 12th Regiment, suffered most; and it was stationed on the soil which had remained longest unturned and untilled on what had been considered a park round the pucka-house, in which the brigadier resided.

I believe that I am right in attributing this sickness exclusively to the circumstances which I have mentioned; and I am afraid that, during the thirty-five years that have since elapsed, similar circumstances have continued to produce similar results.

I am myself persuaded, that had the sward remained unbroken, and the houses and huts been raised upon it, over wooden platforms placed upon it, to secure officers and men from the damp ground, there would have been little or no sickness in that brigade.
The second of the two causes or sources of disease, to which I refer, is the insufficient room which is allowed for the accommodation of our European troops in India.

Within the room assigned for the non- commissioned officers and soldiers, they soon exhaust the atmosphere around of its oxygen or vital air, while they expire or exhale carbonic acid, nitrogen and hydrogen gases, which render it altogether unfit to sustain animal life; and death or disease must soon overtake those who inhale or inspire it.
I may illustrate this by a fact within my own observation.
