That this handbook of clinical tropical medicine has progressed through four editions since 1953 indicates continued acceptance of the authors' original objective, namely, to supply “essential facts as dogmatically and concisely” as possible. The general format remains unchanged with subject material arranged alphabetically and arbitrarily in 47 short chapters. Thus, amoebiasis follows the initial chapter on ainhum, and worm infections and yaws conclude the list. Although new material has been introduced, the authors have managed to limit the length of the text, which has been increased by only 74 pages in the course of the four editions. Chapters in the first edition devoted to subjects such as dracontiasis and yellow fever have by now been integrated with other material, and new chapters have been introduced on subjects such as kuru and lymphomatous syndrome of children. Parenthetically, the term “Burkitt's tumor” appears nowhere in the latter chapter, although the eponym is listed in the index.
