The Blood Ptosis Test.

zero point indicates approximately the condition in which the 

 vaso-tone system is working so poorly that the subject cannot 

 maintain an erect position. This test has been used by many 

 observers to determine the condition of athletes and has been 

 verified by putting the athlete through a test in running, etc., to 

 check up the findings of the test. The results have as a rule 

 verified the observed percentages. This test forms part of the

routine examination in many colleges where athletes are examined 

 by the physical director previous to certification of physical fit- 

 ness. In five cases with five different observers, an athlete has 

 presented himself for certification claiming to be in perfect condi- 

 tion and pointing to previous successful performances. In these 

 cases the vaso-tone percentage was found very low and the candi- 

 date was referred for another examination on the next day. In 

 these cases the candidates did not appear and were found to be ill. 

 Thus it appeared that the test revealed a damaged vaso-tone, 

 before subjective or objective symptoms were apparent. This 

 test has been used to catalogue the effect of various school tasks 

 upon the splanchnic vaso-tone. This test is being used by the 

 New York State Commission on Ventilation to determine the 

 effect of high and low temperature and humidities. In a pre-
