points. Compared with the norm for the final body weight, the lungs averaged 

 24.5 per cent above normal (or 12.8 per cent in the Minnesota cases alone). 

 Compared with the normal for the maximum body weight observed during 

 life, the lungs appeared 4.5 per cent below normal; for body length (height) 

 they appeared 20.6 per cent below normal; while for age they appeared 21.2 

 (16.7) per cent below normal. Some data for individual cases are given in 

 Table 3. These weights indicate that the lungs in atrophic infants have suffered 

 relatively less in weight than has the body as a whole. The lungs are markedly 

 affected in weight by congestion, however, so conclusions are somewhat 

 uncertain.

Fig. 95. — Graph showing the individual weights of the lungs, according to body length, 

 in atrophic infants. The larger dots represent original Minnesota cases; the others are from 

 various sources. The curve of normal weight of the lungs is from data compiled by Prof. 

 R. E. Scammon. The e is marked individual variation, though the weight is subnormal in 

 most cases. 



In animals, Lucas (1826) found no abnormality in the appearance of the 

 lungs after death from starvation. In starved dogs and rabbits, Collard de 

 Martigny (1828) observed that the lungs were pink, crepitant and bloodless; 

 the tracheal mucosa pale. This was confirmed by Bourgeois ('70). 



Chossat ('43) in pigeons on total inanition, with average loss of about 40 

 per cent in body weight, found a loss of 22.4 per cent in the weight of the lungs 

 and of 21.4 per cent in the trachea and larynx. 



In a starved cat with loss of about 50 per cent in body weight, Bidder and 

 Schmidt ('52) noted an apparent loss of 25.9 per cent in the lungs, and of 26.2 

 per cent in the larynx and trachea. In a cat losing 33 per cent in body weight, 

 Voit ('66) observed an apparent loss of 17.7 per cent in the weight of the lungs.
