![PREFACE TO THE ENGLISH EDITION Three years have elapsed since the publication of Professors Laveran and Mesnil's ' Trypanosomes et Trypanosomiases.' When the work appeared it contained practically all that was known about the subject at the time ; consequently, it has been an indispensable book of reference to all subsequent investigators in this particular branch of pathology. During the past three years a great deal of work has been done in Europe, Asia, Africa, and America upon the life-history and development of the trypanosomes, as well as upon the trypanosome diseases of man and the lower animals. The great activity in this direction is, no doubt, largely due to the stimulus given by the discovery (made in 1903) that sleeping sickness is a stage of human trypanosomiasis—in fact, that it is a human tsetse- fly disease. This large output of original work—over 200 new references to recent papers are given in this edition—has made it necessary to do more than merely publish a translation of the original book. The work has been brought thoroughly up to date, considerable additions being made to practically every chapter. All such additions are enclosed within square brackets [ ], and for the added matter I alone am responsible. Among the most important additions may be mentioned: The spirochetes; the Leishman-Donovan body; several new trypanosomes of small mammals, birds, Batrachians, and fishes ; recent observations on the occurrence of flagellates in tsetse-flies, mosquitoes, leeches, etc., and the possible relation of these parasites to the sexual forms of the trypanosomes of vertebrates ; the recent observations upon the prevalence of human and animal trypano- somiases in various parts of Africa and in Asia ; many facts in con- nection with human trypanosomiasis ; and the microscopic changes found in the central nervous system in sleeping sickness and in dourine. A new chapter has been written on the ' Treatment of the Trypanosomiases.' The result of incorporating all the latest information has been to increase the work by more than one half the original size ; but by the use of a larger page, and the rather free use of closer type for a con- siderable portion of the added matter, the book contains only 100 pages more than the original. The labour involved in carrying out the work has been very great—far greater, indeed, than I anticipated](https://iiif.wellcomecollection.org/image/b21172286_0009.jp2/full/800%2C/0/default.jpg)
