In preparing this, the third edition of his work, the author has revised the text thoroughly to accord with dermatologic advances since former editions, and given the reader entire new sections on bulpiss, bunion, Roentgen ray dermatitis, blastomycetic dermatitis, lupus pernio, pityriasis alba atrophicans, and idiopathic multiple pigmented sarcoma. An appendix contains formulæ. Throughout the work, symptomatology, diagnosis, and treatment have received greater consideration than etiology or pathology, and, as in former editions, the arrangement of the different diseases is alphabetic.
