...regrettable being animal food suitable to some, a poison to other stomachs. Indeed, kinds of food that will nourish one man will poison another. I knew a physician who never ate oysters without being seized with Hemiplegia. In short, uniformity in digestive powers is as difficult to attain in a Regiment, and as absurd to demand, as it would be to order every soldier to wear concave spectacles to suit his vision. Ventilation is another great requisite in Barracks, - ventilation by approved and scientific apparatus. On this point there prevails a very common error. Ventilation is effected in various ways, generally, either under a misconception of the nature of the vitiated air, or of its specific gravity. The gas usually so injurious in a crowded room is carbonic acid, whose specific gravity is greater than that of atmospheric air. Consequently, the usual methods of ventilation, by openings in the ceilings, will have little effect in expelling it. The ventilating apertures should be below as well as above, and, even then, some pneumatic power is requisite to expel foul air. In the absence of this, there should be a fire continually burning in an open grate, which would create a current in the chamber and a vacuum in the lower part of the flue, to which all foul air would tend.

The topographical matters and sources of malaria are fourfold: its situation, the nature of its soil and vegetation, the intensity of its heat, both direct and radiated, its humidity, the prevalence of electricity, and the habits of the people. The range of hills on the southern and western aspects of the island exclude the south-west winds, the air becomes stagnant in the amphitheatre, and its constituents are brought into dangerous affinities with adventitious gases.
