SIR JOHN SINCLAIR.

Sir John Sinclair, an eminent British surgeon, says, "I have wandered a good deal about the world, my health has been tried in all ways, and, by the aid of temperance and hard work, I have worn out two armies in two wars, and probably could wear out another before my period of old age arrives. I eat no animal food, drink no wine or malt liquor, or spirits of any kind; I wear no flannel; and neither regard wind nor rain, heat nor cold, when business is in the way."
