HOFFMAN. TO Sir JOSEPH BANKS, Bart. PRESIDENT OF THE ROYAL SOCIETY. SIR, The DOMESTIC MEDICINE having been honoured, on its first appearance, with the patronage of your learned and worthy Predecessor, the late Sir JOHN PRINGLE, I beg leave, in a more improved state, to dedicate it to you, as a small, but sincere, testimony of that veneration and esteem with which I have long beheld the Man who, born to ease and affluence, had resolution to encounter the dangers of unknown seas and distant climes, in pursuit of useful Science; and whose constant object has been to render that Science subservient to the happiness and civilization of Society, I have the honour to be, with great respect, SIR, Your most obedient servant, London, Nov. 10, 1783.
