This is his additional and closing sen- 

 tence designed to be a finality of invincible 

 logic : 



Wer diese genannten angeborenen Sarkoma- 

 formen als durch Bakterien erzeugt betracMet, 

 iibernimmt damit die Verpflichtung, auch fiir die 

 Bildimg seiner eigenen normalen Gewebe und 

 Organe eine bakterielle Infektion. nachzuweisen. 



To which may be answered: Very well, 

 and why not? Since a bacterial organism 

 does just that in the plant ! 



I believe these old ideas and assumptions 

 must be sifted, turned and overturned, and 

 many of them wholly rejected if we are to 

 find the truth. 



Cancer, according to my notion, is a 

 problem for the experimental biologist and 

 the bacteriologist. The morphologist has 

 gone as far as he can go and the energy of 

 cancer research from now on must, I be- 

 lieve, be turned into new channels, if we 

 are to expect results commensurate with 

 the needs of humanity.

ESTABLISHMENT OF A SCHOOL OF 



HYGIENE AND PUBLIC HEALTH 



BY THE ROCKEFELLER 



FOUNDATION 



In recognition of the urgent need in this 

 country of improved opportunities for train- 

 ing in preventive medicine and public-health 

 work and after careful study of the situation 

 the Rockefeller Foundation has decided to 

 establish a school of hygiene and public 

 health in Baltimore in connection with the 

 Johns Hopkins University, where it is be- 

 lieved that the close association with the Johns 

 Hopkins Medical School and Hospital and 

 with the school of engineering of the uni- 

 versity furnish especially favorable conditions 

 for the location of such a school. Dr. William 

 H. Welch, now professor of pathology, and Dr. 



William H. Howell, professor of physiology 

 in the university, will undertake the organiza- 

 tion of the new school in its inception. The 

 trustees of Johns Hopkins University have ap- 

 pointed Dr. Welch as director of the school, 

 and Dr. Howell as head of the physiological 

 department. 



Funds will be provided by the foundation 

 for the purchase of a site and the erection of 

 a suitable building, in proximity to the hos- 

 pital and the medical laboratories, to serve as 

 the institute of hygiene, which will be the cen- 

 tral feature of the school. Here will be housed 

 various laboratories and departments needed 

 in such a school, such as those of sanitary 

 chemistry, of physiology as applied to hygiene, 

 of bacteriology and protozoology, of epidemi- 

 ology and industrial hygiene, of vital statis- 

 tics, a museum, library, etc. Additional facil- 

 ities for instruction and research will be sup- 

 plied by the medical and engineering schools, 

 the hospital and other departments of the 

 university. Funds will be provided by the 

 foundation for the maintenance of the school 

 in accordance with plans which have been 

 submitted. 



It is expected that the school will be opened 

 in October, 1917, as it is estimated that a year 

 will be required for the construction and 

 equipment of the institute and the gathering 

 together of the staS of teachers. 



As it is recognized that the profession of the 

 sanitarian and worker in preventive medicine, 

 however closely connected, is not identical 

 with that of the practitioner of medicine and 

 requires a specialized training, the school of 

 hygiene and public health, while working in 

 cooperation with the medical school, will have 

 an independent existence under the univer- 

 sity, coordinate with the medical school. 



The school is designed to furnish educa- 

 tional and scientific opportunities of a high 

 order for the cultivation of the various sci- 

 ences which find application in hygiene, sani- 

 tation and preventive medicine, and for the 

 training of medical students, physicians, engi- 

 neers, chemists, biologists and others properly 

 prepared, who wish to be grounded in the 

 principles of these subjects, and above all for
