Mosselman and Lienaux's "Manuel de Microbioloyie Veterinaire," . my object has been to supply English speaking veteri- nary students and practitioners with a work on Bacteriology which seemed specially adapted to their needs. The book is small, but it conveys more in- formation on the etiology of the infectious diseases of animals and the biology of the germs associated with them than any other single work in our language. Unlike other works on Bacteriology accessible to readers of English only, the Microbiology of animal diseases is treated of as the essential part of the work, that of diseases of ally referred to. mankind only incident- to details The completeness and accuracy as with which it discusses the modes of prop- agation of some of our most important diseases and the general conditions under which these diseases occur, ought to veterinarians, recommend the book who are presumably more to practical interested in the ascertained facts in regard to any disease than in the individuality of the germ which occasions it. The book is not intended for a laboratory manual, consequently, the technique of staining and cultiva(iii) iv Preface. tion of germs is not exhaustively discussed, and the usual illustrations of bacteriological apparatus have been omitted. As : to the translation itself a few words are neces- sary Weights and measures, given in the metrical system in the original, have not been changed. Dimensions which occur in this work are chiefly those of microscopic objects which are now rarely ex- pressed by American microscopists in fractions of an The thermometric readings are in all cases given in the centigrade scale. For those who are unfamiliar with the decimal system the Appendix inch. will supply the requisite information. The few some foot-notes which I have introduced are in cases intended to be supplementary to the text, referring to discoveries which have been made since the publication of the original in 1891. In other cases they are explanatory of words or statements which might otherwise be misunderstood. To the illustrations which occur in the French text I have added a few others borrowed from differtions ent sources, which are acknowledged in the descripaccompanying the figures four are from draw; ings of preparations in my own possession.
