The writer remained with these men during the entire time of the 

 experiment and made the observations. The men were told that if they 

 cared to do so they could take a nap or smoke, or occupy themselves 

 as they pleased. They all settled themselves for a restful afternoon, 

 but in a very little time they became wakeful and restless. After sitting 

 on the settees for a short time they began to walk around the room. 

 They smoked and carried on fragmentary conversation, but the restless- 

 ness remained during the afternoon. Sweating was very profuse and 

 the clothing soon was saturated. A noticeable change took place in 

 the character of the respiration; inspiration became slow and deep with 

 quick expiration and then an interval before the next inspiration. The 

 pulse in each case retained its quality, the only change being in its 

 rapidity. Each of the four men denied the presence of headache or 

 other disagreeable symptoms, although the writer suffered from quite 

 a severe headache. All felt tired and relaxed at the close of the 

 experiment and without appetite for the evening meal. Drowsiness 

 quickly supervened upon the restlessness after quitting the bathroom. 

 No effects were experienced by the men the next day. 



Observations of a somewhat similar character were made upon fifteen 

 men of a baseball squad. The men were seen on three of the hottest 

 daj r s in August, the temperature according to Manila observatory 

 reaching 93° F. each day and the relative humidity approximately 80 

 per cent. The sun temperature on the field could be made to register 

 up to 130°, according to how much reflected heat reached the instru- 

 ment. During the time, the sky was cloudless but there was a very 

 moderate wind. The observations were taken after about two hours 

 of hard baseball practice, from 1.30 to 3.30 in the afternoon. The 

 men were perspiring freely and most of them were red of face from 

 the exercise. The average of the temperatures taken under these con- 

 ditions was 99°.7 P., the lowest being 99° and the highest 100°.4. 

 The blood-pressure readings gave an average of 129.3 millimeters, the 

 average at the beginning being 120.7 millimeters. It was not possible 

 to get the pressures on all of the men after the effects of the exercise 

 had worn off, but they were obtained in six cases, when the average 

 was 121.5 millimeters, the same men giving an average of 129.5 milli- 

 meters after exercise. 



THE CLIMATE. 



The following short summary of climatic conditions in the Philip- 

 pine Islands is introduced at this time so that the important features 

 may be fresh to the mind in considering the final decision of the test. 

 The climate varies somewhat throughout the Islands, but a considera- 

 tion of the climate of Manila will answer for that of the entire lower 

 elevation which comprises the great bulk of the inhabited parts of the 

 Islands. To the newcomer who arrives in Manila, the climate seems
