314 HEISER AND CALDERON. 



SECOND WEEK. 



The Mork of the second week of the congi-ess was divided into seven 

 sections, at which over 600 papers were read. Each section was presided 

 over by a chairman who had an international reputation in the special 

 field of work over which he presided, viz : 



Section 1. — Pathology and bacteriology, Dr. William Welch. 



Section 2. — Clinical study and therapy of tuberculosis, Dr. Vincent Bowditch. 



Section S. — Surgery and orthopedics. Dr. Charles IT. Mayo. 



Section -'/. — Tuberculosis in children, Dr. Abraham Jacobi. 



Section 5. — Hygiene, social, industrial, and economic aspects of tuberculosis, 

 Edward T. Devine. 



Section 6.— State and municipal control of tuberculosis, Dr. Walter Wyman. 



Section 7. — Tuberculosis in animals and its relation to man. Dr. Leonard 

 Pearson. 



All sections met daily from 9 to 12 and from 2 to 5, and at times two 

 sections held combined meetings to discuss questions of common interest ; 

 a general meeting of all sections was also held every night, beginning at 

 8 p. m. 



Under the section entitled "The State and municipal control of 

 tuberculosis," the papers were read which were deemed to be of the 

 most practical interest to the Philippine Islands, and, consequently, the 

 greater portion of our time was devoted to this section. 



On September 29, Doctor Heiser read a paper entitled "The tubercu- 

 losis problem in the Philippines and the elimination of intestinal parasites 

 as the first step in its solution." On October 1, Doctor Calderon read a 

 paper entitled "Notes on tuberculosis in the Philippines." 



The scientific work of the congress showed clearly that remarlcuble unanimity 

 prevailed among the delegates upon the following points : 



1. That tuberculosis in its early stages is a curable, disease. 



2. That it is a house disease; that is to say, that people who live an outdoor 

 life are not afflicted with tuberculosis, and the more confined the living quarters 

 are the more prevalent is tlie disease. 



3. That it is a simple and practicable matter to avoid contracting tuberculosis 

 by introducing large volumes of air into the house, night and day, winter and 

 summer, or, better, by sleeping out of doors altogether. 



4. That among the best ways to cure tuberculosis is to live an outdoor life, 

 regardless of what the climate may be, with only such exercise as a physician 

 prescribes and a good, simple diet which should consist mainly of eggs and milk. 



6. That the successful treatment of the disease is not necessarily confined to 

 specially favored localities, but that many cures may be effected in almost any 

 climate or locality. 



THIRD WEEK. 



The tliird week of the congress was devoted to a continuation of 

 the exhibition, lantern demonstration, lectures, and visits to Baltimore 

 and tlie near-by places at M'hich tubercular sanatoria are located.
