him of all blame for the disaster, he was appointed in February 1812 to the Hannibal, off Cherbourg, and in May to the Niemen, which he commanded for the next three years on the West Indian station.
He was nominated a C.B. on 4 June 1815; in 1830–1 he commanded the Kent in the Mediterranean; was promoted to be rear-admiral on 10 Jan. 1837, and was made a K.C.B. on 25 Oct. 1839. From 1841 to 1846 he was admiral-superintendent at Devonport, and in the autumn of 1845 commanded the experimental squadron in the Channel. He became a vice-admiral on 13 Feb. 1847, admiral on 17 Dec. 1852, and died at the Royal Hotel, Southampton, on 2 Oct. 1855. He married, in 1802, a daughter of Edward Lockyer of Plymouth, and had issue.

PYM, Sir WILLIAM (1772–1861), military surgeon, son of Joseph Pym of Pinley, near Henley-in-Arden, Warwickshire, and elder brother of Sir Samuel Pym [q. v.], was born in Edinburgh in 1772, and was educated in the university. He entered the medical department of the army after a brief period of service in the royal navy, and was shortly afterwards ordered to the West Indies. In 1794 he was appointed to a flank battalion commanded by Sir Eyre Coote [q. v.], in the expedition under Sir Charles Grey which landed at Martinique in the early part of that year. He was present at the reduction of Martinique, St. Lucia, and Guadaloupe. The force to which he was attached suffered great hardships, but remained healthy until the fall of Fort Matilda completed the surrender of Guadaloupe, when yellow fever broke out in the 35th and 70th regiments, then stationed at St. Pierre in Martinique. Pym was ordered to take medical charge through the outbreak, which lasted during 1794, 1795, and 1796, when it is estimated that nearly sixteen thousand troops died. Pym thus obtained an unparalleled knowledge of yellow fever.
He served in Sicily on his return from the West Indies, and in 1806 he was shipwrecked in the Athénienne of 64 guns on the Skerri shoals between Sicily and Africa. In this wreck 349 persons perished out of a crew of 476, and the few survivors owed their safety in great measure to the activity and resources of Pym. He was transferred from Sicily to Malta, and afterwards to Gibraltar, where he acted as confidential medical adviser to the governor, the Duke of Kent. He was also appointed superintendent of quarantine. He became deputy inspector-general of army hospitals on 20 Dec. 1810, and in the following year the Earl of Liverpool sent him back to Malta as president of the board of health, a position he filled with conspicuous success. He returned to England in 1812 and lived in London, but in 1813 he volunteered to proceed to Malta, where the plague was raging. He was appointed inspector-general of army hospitals on 25 Sept. 1816.
In 1815 he published an account of yellow fever under the title of ‘Observations upon Bulam Fever,’ proving it to be a highly contagious disease (London, 8vo). This is the first clear account of the disease now known as yellow fever. In this work Pym maintains (1) that it is a disease sui generis known by the name of African, yellow, or bulam fever, and is the vómito prieto of the Spaniards, being attended with that peculiar and fatal symptom the ‘black vomit;’ (2) that it is highly infectious; (3) that its infectious powers are increased by heat and destroyed by cold; (4) that it attacks natives of warm climates in a comparatively mild form; (5) that it has also a singular and peculiar character, attacking, as in a case of smallpox, the human frame only once. The work excited violent opposition at the time, but it is now generally conceded that Pym's views are substantially correct. In ‘Observations upon Bulam, Vómito-negro, or Yellow Fever,’ London, 8vo, 1848, which is practically a second edition of the previous work, Pym contends that the question is no longer one of contagion or non-contagion, as it was in 1815, but whether there are two different and distinct diseases—viz. the remittent and non-contagious, which prevails at all times on the coast of Africa; and the other, the bulam or vómito-negro fever, which only occasionally makes its appearance, and is highly contagious.
In 1826 Pym was made superintendent-general of quarantine, and, in that capacity, took every opportunity of relieving the existing stringency of the laws of quarantine. His services were recognised in a treasury minute dated December 1855. He proceeded to Gibraltar in 1828 to control and superintend the quarantine arrangements during an outbreak of yellow fever, and upon his return to England he was invested by William IV a knight commander of the Hanoverian order. Pym was a chairman of the central board of health during the epidemic of cholera which attacked England in 1832, and for his services received a letter of
