him, which frequently involved the expenditure of much 

 time and trouble on account of the special character of 

 the work. 



Amonof the o^entlemen to whom I am indebted for having^ 

 granted me permission to have their horses photographed, I 

 have the honour to number : His Grace the Duke of West- 

 minster, Colonel Anderson, Captain Woolmer, Captain Mow- 

 bray of the Black Watch, Mr. W. H. Walker, Mr. A. A. 

 Apcar, Mr. Tom. Jennings, junr., Mr. Spooner Hart, Messrs. 

 Milton and Co., Messrs. Ralli and Co. of Sydney and 

 Calcutta, Messrs. Cook and Co., Mr, Oscar Dignam, Mr 

 E. Gregory, Mr. Vansittart, Mr.. Steve Margarett of Mel 

 bourne, Mr. John Stevens of New Zealand, and Colonel Simp- 

 son. I am greatly obliged to Mr. Frank Haes, Major Nott, 

 and Mr. Dixon, 112 Albany Street, N.W., for the negatives 

 they have lent me ; to Sir William Flower for allowing me to 

 take photographs of Figs. 187, 188 and 189, in the South 

 Kensington Museum ; to Professor C. Stewart for similar 

 permission with respect to Figs. 185, 190, 197 and 201, in 

 the Museum of the R.C.S. ; and to the Zoological Society 

 for the loan of Figs. 181, 182 and 183. The action shown in 

 the figures of the paces and of the leap has been adopted 

 from the admirable photographs done by Mr. E. Muybridge, 

 and published in \{\?, Animal Locomotion ; although the artistic 

 "treatment" of the horses is oriofinal. This matchless 

 American work is solely a collection of photographs, and does 

 not contain any analysis of the movements of the horse. I 

 may also mention that the photographs of Anschtitz, on the 

 same subject, are excellent. 



In order to facilitate comparison, I have tried, as far as I 

 have been able, to get the portraits of the horses, asses and
