RESPIRA TION. 125 



(7) Test with the pneo manometer the force of inspira- 

 tion and expiration. (Appendix, A 14). Let each 

 member of the division test with the pneo-manometer 

 the maximum positive pressure which he is able to 

 produce in the respiratory passages during expiration. 



(8) Test with the same instrument the maximum nega- 

 tive pressure which each individual can produce 

 during inspiration. 



(9) Does the face become red in either of these tests? 

 If such is uniformly observed, account for it. 



(10) The preservation of data. Experience has shown 

 that when data are to be preserved for subsequent use 

 in the comparison of one class of individuals or cases 

 with another, it is very much more economical in time 

 to record the data upon cards. 



For the above data one may use such a card as is 

 appended to this chapter. 



In addition to the measurements above given record 

 upon the cards the weight, the height, the bodily condi- 

 tion of the individual, and especially whether the indi- 

 vidual has lived in a hilly or in a flat country, and 

 whether he has been active or inactive.
