already received from the readers of The Yorkshire Post, justify, we 

 think, this anticipation of ours. 



It is well to add that most of the cases described have actually 

 occurred in the practice of Mr. J. B. Gresswell, and that the treatment 

 mentioned and recommended is that usually carried out by him. 

 The whole of the literary and pathological portion of the work has fallen 

 to the lot of Dr. Albert Gresswell ; but the principal part of the recent 

 revision, alteration, and correction, of the whole work as opposed to the 

 original articles as they appeared in The Yorkshire Post, has been 

 carried out in co-operation with Dr. Gresswell, by Mr. George Gresswell, 

 who also has re-written certain portions here and there, both in the 

 •original articles, and in the body of the book as it now stands, as well as 

 the introduction. 



To Professor J. M'Fadyean, of Edinburgh, we are indebted for the 

 two valuable illustrations of the horse's brain, and to him also we owe 

 our frontispiece and the description of it. 



In addition, we have in conclusion, to acknowledge our indebtedness 

 to the following : — 



Firstly and chiefly, to the prolonged and extensive experience of 

 the late Mr. D. Gresswell ; and also to the admirable and classical 

 researches of Drs. Fleming, Klein, and Cobbold, to Messrs. Percivall, 

 Williams, Gamgee, Signol, Charles Gresswell, Mayhew, Brown, Chauveau, 

 and others.
