but regular sun-stroke such as we get in the 

 north, I never encountered in the south. 



An interesting point along therapeutic lines I 

 learned in the extreme western part of Texas, 

 where the altitude is very high, being sometimes 

 5,000 feet above sea level. This point was in 

 regard to the treatment of pneumonia, and other 

 febrile conditions, but pneumonia most especially, 

 and consists in the fact that one must be very 

 careful in the use of heart depressants such as 

 acetanilid, phenacetin, all coal-tar products, and 

 even quinin. 



The doctor who treats his pneumonia cases 

 there as most of us do in the lower altitudes will 

 have many deaths, usually in the first day or two 

 of the attack. Pneumonia patients in those alti- 

 tudes truly die of heart exhaustion, and few fatal 

 cases live over a few days. It is a good place in 

 which to take lessons in the treatment of this dis- 

 ease — lessons that are valuable in any altitude.
