Cadogan’s famous essay laid down rules on the nursing, feeding, and clothing of infants, and filled a great need at a time when infant welfare was much neglected through the ignorance of those concerned. As a result of this work, Cadogan was elected a physician of the Foundling Hospital in 1754. He became a friend of Garrick, and was present at that great actor’s deathbed. 10th ed., 1772.
