APPENDIX TO SECOND EDITION, 153 



** began to run down," as he said, " and became 

 quite seedy"; so much so that the experimenter grew 

 ashamed of the animal's appearance. There was in 

 this case no question but what the amount given was 

 liberal enough (unless his own stable-man deceived 

 him — which he felt sure was not the case), but the 

 truth in the matter was simply this : the horse was 

 fat. His work had been light, and his diet heavy. 

 Accustomed to his over-liberal feed every five or six 

 hours, he had become really unsound throughout, as 

 explained on page 21 (''A Soft Horse"). He had to 

 be built from the ground up, as per examples on pages 

 17-20-24-25, or else remain as he was, unfit for hard 

 service and predisposed to sickness. He finally 

 worked the case out successfully. With horses that 

 are and have long been " out of form," i. e., pretty 

 thoroughly degenerated (and the older the creature 

 and the longer he has been thus diseased, the worse 

 for him), any radical change — whether increase of 

 work, decrease of food, or less frequent meals — would 

 speedily " show them up " — expose their real condi- 

 tion ; but if the regular daily exercise is maintained 

 no animal will shrink in muscle, however much he 

 may in weight. He has, we will assume, taken on 

 (and in and through) himself a large amount of fat, 

 because overfed and underworked. His muscles are 

 honeycombed with fat ; but being stimulated with a 

 meal every few hours he maintains an appearance of 

 strength, as, on account of fat, he does of condition — 

 can travel sharp and strong for a short distance. If 

 sent on a long journey he is used up for several days.
