When this book appeared we said in the review of it (JOURNAL, Vol. XII, p. 105), 'There should be a good demand for this excellent little book.' The present is the fourth edition, and it seems to gain in accuracy and completeness with every edition. The author has been complimentary

enough to incorporate all the suggestions made in the previous review of his book and there are only a very few to be made on the present occasion. The sign psa might be added to the word 'pre-conscious' (German vorbewusst)—a term invented by Freud. The words 'ego-syntonic' and 'ego-dystonic' might well be added to the dictionary. We doubt whether the definition given of 'dromomania' (as being equivalent to Wanderlust) is correct: the Greek word means to run at full speed, so that dromomania would describe very well the modern craze for high speed.
