Total number of maximal temperatures where the first day exceeds that 

 of the second, 72. 



Total number of maximal temperatures where the first day equals the 

 second day, 7. 



This indicates that the temperatures run a little lower on the second 

 day than on the first although it cannot by any means be depended upon. 



TIME OF DAY WHEN THE MAXIMAL AND MINIMAL TEMPERATURES OCCUR. 



This study does not include the twenty-four hours of the day, but is 

 confined to those hours in which the temperatures are most likely to be 

 taken. The normal temperatures alone are used. 



The total number of temperatures during the given hour is found, then 

 the number of maximal and minimal temperatures occurring during that 

 hour. By following this method a fair idea of the hours, in which the 

 maximal and minimal temperatures are to be found, can be obtained. 



It is readily seen that no reliance can be placed upon any hour as repre- 

 senting the highest number of maximal temperatures or minimal tem- 

 peratures. Furthermore, there is a great difference in the relation of 

 maximal and minimal temperatures in the two tests given. In March,, 

 the five o'clock hour has a larger number of minimal temperatures than 

 maximal temperatures, while in September the order is strikingly re- 

 versed. This is more or less true throughout the table, no harmony pre- 

 vailing at all. We cannot select any hour, therefore, with the hope of 

 securing the maximal temperature and allow it to stand as a representa- 

 tive normal temperature. A large number of normal temperatures are 

 required to give a satisfactory notion upon which to base judgment. 



A RESPONSE TO TUBERCULIN. 



We have placed the stress of our work upon normal temperatures, for 

 they are in reality the foundation of interpretation. Knowing what the 

 normal temperatures may lead to, any deviation from the normal may
