PREFACE. XI 



which in fascicula had been only a succinct epitome, by- 

 giving more elaborate explanations with the aid of 

 demonstrations either at horse shows or in the manege. 



In spite of the encouragement I was perpetually 

 receiving, I nevertheless hesitated to reissue the slender 

 work, the edition of which was exhausted. The 

 insistance of many workers who were interested in these 

 hippie studies, and the following letter from Dr. Marey 

 (member of the Institute), whose singular experiments 

 upon the gaits of animals have acquired high scientific 

 value, induced me to revise my first publication for the 

 purpose of adding more detailed observations, as well as 

 new explanatory drawings. 



" My dear Colonel, 



Much has been said of the mutual co-operation which art and science 

 should lend one another for the perfection of each ; but to effect this 

 reconciliation, it was necessary to unite, as you have done, practical 

 knowledge to powers of execution of such kind as your first work afforded 

 us proof. 



Give a series of plates in which the truth of the attitudes of the horse 

 in motion be united to correctness of form, and you will render a great 

 service to artists. 



Certain masters have already, in this matter, done something to 

 improve the taste of the public ; consummate this instruction and soon 

 neither convention nor caprice will be accepted. Great success to you, 

 dear Colonel, and believe in my affectionate devotion. 



Marey." 



I shall exert myself to the utmost in response to the 

 over-indulgent opinion of the learned professors ; and, in 

 the hope of being of use to all who love and observe 

 horses, I am happy to dedicate to them a more complete 

 study than the first. 



E. Duhousset.
