ADDRESS. ci 
And yet it was these very evils which but two years ago brought the noble 
army of a mighty nation, at the close, too, of a glorious campaign, to almost 
the verge of destruction.” 
I may allude to one other point which sanitary science would suggest to 
the administrator in reference to the clearly-ascertained effects of too little 
pure air, and too much foul air inspired continuously during a given 
period. 
The skilled soldier being of a given value when landed healthy and strong 
in the Crimea or at Calcutta, query, whether it be more economical to carry 
1000 in one ship, landing 500 sick, enfeebled, and prepared to fall into 
and engender ‘epidemics, or to carry the 1000 in two such ships, and land 
them healthy and fit for action? The same administrative question applies to 
barracks and hospitals. 
One noble use and adequate application of so vast a triumph of naval 
architecture as Mr. Scott Russell’s ‘ Leviathan’ would be its carrying troops 
in good condition as regards health, for which its capacity especially fits it. 
When authority becomes impressed with a conviction stimulating to action 
of the importance of sanitary science, it will insist on the possession, by the 
army medical officers, of the elements of that science as well as of the prin- 
ciples of practice in the cases of disease and the treatment of wounds. But, 
in order that an army may benefit by the doctors’ knowledge of preven- 
tive medicine, authority should direct preliminary examinations and reports 
of sites for encampment,—of buildings for barracks and hospitals,—of 
clothes for extreme climates, and the like, and should command that such 
reports be acted upon, where no urgent circumstances or inevitable move- 
ments preclude the adoption of the means for the prevention of decimating 
fevers and choleras. 
Bonaparte’s military science was characterized by the rapid concentration 
of his forces upon a given point. A like success and superiority may attend 
the commander who keeps the greatest proportion of his men in good work- 
ingtrim. The healthier the man the longer and quicker will he march. And 
the care which foresees and provides for the efficient fighting order of a 
force is quite compatible with the most intrepid handling of that force in the 
field of battle. 
As to the dense populations in civil life, the number of towns in England 
in which the sewage is rapidly, efficiently, and economically carried off by 
water-power and hydraulic apparatus, constitute so many experimental 
demonstrations of the success attending a proper unintermitting water-supply 
and co-adjusted system of tubular drainage. Lancaster, Penrith, Alnwick, 
Barnard Castle, Rugby, Croydon, Ely, are instances in which are demon- 
strated the diminution of fever and other causes of untimely death,—the 
augmentation of the cleanliness and comfort of the wage-classes,—the eco- 
nomy in the wear of all washable articles through the supplies of pure water, 
—collateral and unexpected economies in regard to fire-insurance, from the
