(/.) GERMANS, 1,343 MEN. 



It is difficult to obtain from the statistics of recruiting in any country an accurate 

 estimate of the proportion of men who have been rejected for deficient size of chest, 

 as other and more prominent causes of exemption are certain to inckide such cases. 

 In England, in 1869, the proportion of recruits rejected for "malformation of chest and 

 spine" was 30.26 per 1,000; in 1870, it was 28.75 per 1,000. During the same years, 

 38.71 and 33.15 per 1,000 were also rejected for "muscular tenuity and debility."' It 

 is impossible to determine from these details how many of the men thus classified 

 were mai-ked by a deficient size of chest, though a minimum of thoracic girth is estab- 

 lished for each corps of the English army. 



The statistics of the American army, from 1839 to 1855, collected by Dr. 

 Coolidge, give 260 men as rejected for "malformed and contracted chest," out of 

 5,000 examined'; being at the rate of 52 per 1,000; at the same time, however, there 

 were rejected, in addition, the following classes : 



Not robust, too slender 467, or 93.4 per 1,000. 



General unfitness 150, or 30.0 per 1,000. 



General malformation 110, or 22.0 per 1,000. 



Spinal curvature 48, or 9.6 per 1,000. 



825- 

 It is evident that many of the men thus described might also have been properly 

 included in the cases of deficient size of chest.
