ANIMAL MECHANICS. 



life, I had expressed the opinion that his chief muscular 

 peculiarity consisted in the development of the shoulder 

 muscles — a conclusion which was fully borne out by the post 

 mortem examination. If we regard " Master Magrath" as the 

 unit of comparison, we find the percentage of the average 

 Greyhound to be — 



In Hip Joint, . . . . 78.04 per cent. 

 In Shoulder Joint, . . 75-56 ,, 



These figures show the muscular superiority of " Master 

 Magrath," and the greater development of the muscles of 

 his shoulder. 



In the following Table, I have collected into groups the 

 muscular percentages of various Canidas, for the purpose of 

 comparison : —

This Table shows the great muscularity of the Greyhounds, 

 for the only dog that excels them is the Mastiff, which is a 

 much larger and heavier animal. It may be worth adding 

 that "Master Magrath's" running weight was 54 lbs.
