Excerpt from Index-Catalogue of Medical and Veterinary Zoology: Subjects, Trematoda and Trematode Diseases The index-catalogue of Medical and Veterinary Zoology represents the combined card-catalogues of the Zoological Division of the United States Bureau of Animal Industry and of the Zoological Division, Hygienic Laboratory, United States Public Health and marine-hos pital Service. These catalogues are arranged in three sections: Authors, Subjects, and Hosts. Object OF index catalogue - The object in publishing the cata logue is to place it in permanent form. There have been four fires in the two laboratory buildings, but fortunately none of these gained headway. Were either building to be destroyed, and any part of the catalogue to be lost, the inconvenience such loss would entail in the regular work would be very extensive. By having the catalogue in printed form, it is made more accessible, and accidents are guarded against. By placing it at the disposal of other workers it is hoped to render their work less arduous, and especially it is desired to reduce the confusion in nomenclature.
