of sheep, Diphtheria and Contagious Epithelioma of fowls, 

 Sfurvy, Coecidial Dysentery of cattle. Enzootic Paralysis of the 

 s])inal cord in horses, Paralysis of the bladder and the Psj^- 

 choses have been rewritten entirely. Finally essential changes 

 will be found in the chapters on Specific Paratuberculous Enter- 

 itis of cattle, the parasitic diseases and the skin diseases ; also 

 in the therapeutic portions of most chapters. 



Great care has again been taken with the illustrations. 

 Some less good illustrations in the earlier editions were replaced 

 ))y new ones, and the mnnber of illustrations in the text (some 

 of them in colors) has been increased from 319 to 361, that 

 of the plates (which are mostly in colors) from 6 to 15. We 

 wish to express our acknowledgments to Messrs. Ladislaus 

 Tatz and Leopold Kalmar for the colored designs, and to Messrs. 

 Eugen Raitsits and Eugen Schwanner for the photographs and 

 drawings. 



In order not to enlarge the already considerable size of the 

 work, the text was condensed wherever possible and small type 

 was made use of more freely. In consequence this edition con- 

 tains only five signatures more than the second, in spite of the 

 many additions and alterations. "We have persisted in our 

 aim to produce a work which should reflect the present state 

 of veterinary medicine as faithfully as possible and should also 

 satisfy the requirements, both of veterinary practitioners and 

 of investigators and human practitioners who desire information 

 on the problems of comparative pathology. The favorable re- 

 ception accorded to the second edition permits us to hope that 

 the present one will be received with like favor. 



The book has recently been published in the Italian language 

 and a Russian edition is being prepared. 



AVhile this edition was in joress, the i:)ublishers suffered 

 the loss of the founder of the house, a loss which we deeply 

 regret. A\^e are indebted to the publishers for their courtesy 

 in meeting our wishes in the preparation of the work.
