building in Edinburgh In 1815, the
Edinburgh Review contained an article on the system of "craniology" devised by
Franz Joseph Gall and
Johann Gaspar Spurzheim, denouncing it as "a piece of thorough quackery from beginning to end". When Spurzheim came to Edinburgh in 1816, Combe was invited to a friend's house, where he watched Spurzheim dissect a human brain. Impressed by the demonstration, he attended a second series of Spurzheim's lectures. On investigating the subject for himself, he became satisfied that the fundamental principles of phrenology were true: "that the brain is the organ of mind; that the brain is an aggregate of several parts, each subserving a distinct mental faculty; and that the size of the cerebral organ is,
caeteris paribus, an index of power or energy of function." around 1825 His first essay on phrenology was published in
Scots Magazine in 1817, and were followed by a series of papers
Literary and Statistical Magazine. The writings were collected and published in 1819 in book form as
Essays on Phrenology and, in later editions, as
A System of Phrenology. In 1820, Combe helped to found the
Phrenological Society of Edinburgh, which in 1823 established a
Phrenological Journal. His lectures and writings also drew attention to phrenology in Europe and the United States. ==Debate with Hamilton==
