Vlll PREFACE. 



preparations of arsenic, hellebore, sulphate of zinc, sulphuric 

 acid, and so forth. 



The experienced surgeon daily engaged in practice has 

 his knowledge always ready, and but seldom needs the 

 help of formulae. Yet for all of us an occasional reference 

 is useful, and sometimes indeed indispensable, and it is 

 wise to avoid the danger of getting into grooves, especially 

 in the case of so progressive a science as that of thera- 

 peutics. Further, although no books can replace that in- 

 stinctive judgment based on a familiar acquaintance with 

 the actions of medicines which is essential for the able 

 prescriber, they certainly are of great value as aids in 

 maturing sucli skill, particularly to those who are not con- 

 versant with modern lines of treatment of disease. 



Should this attempt to facilitate the work of those whose 

 praiseworthy vocation it is to alleviate the sufferings, and, 

 so far as is possible, cure the ailments which are liable to 

 afifect the most important of our domesticated animals, be 

 in some degree successful, we shall feel gratified. 



It will be obvious that when two or several prescriptions 

 are given under one heading, the different formulae are 

 to be looked upon as alternative, unless the contrary be 

 specially stated. Selection is to be made after due con- 

 sideration. 



It is hoped that a marked increase of usefulness may 

 result from the revision and enlargement to which the book 

 has been subjected, the new prescriptions being those of 

 Mr. J. B. Gresswell.
