The man who, without experience or education, undertakes to compound drugs, and, when compounded, to administer them as remedies for diseases of the human body, may justly be pronounced a dishonest adventurer, and an enemy to life and the fair proportions of his fellow-citizens. Quackery is an antient profession in London.
