whence embracing every topic relating to medical topography, to
sanitary arrangements, and to the observed phenomena of tropical

the choice of sites for barracks, the propriety of giving to
soldiers healthy employment and recreation, as a means of averting

he died, after a short illness, at Thursby, near Carlisle, in the
77th year of his age. Thus closed a long career of usefulness; for
