ANTHROPOMETRIC DATA. 233 



GENERAL BODY CONDITION. 



The Du Bois measurements were made for both squads prior to 

 and at the end of the dietetic restriction. With Squad A another series 

 was made at the time of the minimum level. The individual data 

 obtained for the men in Squad A are given in table 13, for the men in 

 Squad B in table 14, and for Fre, Lon, and McM, in table 15. With 

 Squad A the measurements were made on September 29, November 24, 

 and February 2. Several members of Squad A were not measured on 

 all three days. Thus Fre was measured only at the beginning of the 

 experiment, whil^ the first measurement for Kon was on October 27, 

 instead of September 29, and Spe, owing to illness, was not measured 

 on February 2. These were, however, the only exceptions. 



A typical series of Du Bois measurements is given in table 16. 

 The series of measurements selected was made with Can, as his per- 

 centage loss in weight was larger than that of any other member of 

 the squad, both at the minimum weight and at the end of the experi- 

 ment. These observations were made on September 29, 1917, and 

 indicate the character of each measurement. In the tables the meas- 

 urements are referred to by the letters A, B, F, G, H, etc., corre- 

 sponding to their designation in the typical measurements of Can. 



The changes in the body measurements made according to the Du 

 Bois method, as the period of reduced diet progressed, are clearly shown 

 for Squad A by a comparison of the data in table 13, particularly 

 those for the circumferences. Practically every girth decreased per- 

 ceptibly as the research continued. Attention must, however, be 

 called to the fact that certain anomalous measurements appear even 

 in the lengths, but so large a group of measurements enters into the 

 computation of the surface area that, unless a gross error is made in 

 some of the important lengths or circumferences, the variations will 

 have but little influence upon the general accuracy of the value for 

 the total area. These discrepancies are referred to, not so much to 

 lay stress upon their actual mathematical value, which is practically 

 slight, but to emphasize the fact that the traction of the tape and the 

 exact duplication of location are not always the same when two ob- 

 servers are measuring an individual. It was our custom to have each 

 subject measured by two persons and the readings taken were checked. 

 The traction of the tape, however, will always be subject to variation. 

 Furthermore, certain of the landmarks are not always easily recorded 

 to less than a centimeter, particularly some of the greater lengths. 

 On the whole, however, we believe that the measurements are accu- 

 rate and supply reliable data for computing the body-surface of these 

 men. 



As would be expected, the largest losses are found with the maximum 

 trunk girths, i. e., M, N, and Q, and the girth at the perineum, P.
