except love and ambition, the blood and chyle of dramatic poetry, has he written so much. On no other has he written with such mighty power.
Some explanation seems due of the title chosen for this work. Since psychology strictly implies all that relates to the soul or mind of man in contradistinction to his material nature, the character of Othello might have been placed under this title with as much propriety as that of Lear. The derivation and original use of a term, however, not unfrequently differ from its acquired and permanent use, and the term psychology has, of late years, been used to denote all that relates to the department of science which takes cognizance of irregularities and aberrations and diseases of the mind. It serves not to object that the derivation of the word is opposed to such employment, for the same may be said of half the words in the language. Mental pathology would be a far more exact, but also a more cumbrous term; and no further apology need be made term, than that no other with equal convenience. their usefulness and not for the modern use of the shorter suits the purpose to which it is applied, One chooses words, like servants, for for their pedigree.
The author had intended to append to the following pages a chapter on Shakespeare's knowledge of medicine. When, however, it was partly written, he found that the freedom of expression, which the great dramatist had permitted himself on medical subjects, was such as would either have prevented the admission and consideration of important passages, or have forbidden the present work to many readers, whom it is hoped may otherwise honour it with a perusal. The inconvenience therefore of a separate publication has been preferred.
It only remains to add that, three of the following essays have already appeared in the pages of the "Quarterly Journal of Mental Science," a publication edited by the author.
