244 DISCUSSION. 



Heiser truly says, it is for us to do the best we can with our limited 

 means and to discriminate carefully along what lines we should work. 



Doctor Heiser has submitted an extended programme for the future, a 

 programme which would really prove to be a Herculean task, but it is 

 a good thing to see that he is hopeful of ultimate success. It is well, 

 however, that those of us who have had the privilege of seeing some- 

 thing of the actual working of the Bureau of Health should look back 

 and consider what had already been done to improve the sanitary condi- 

 tion of the people. In a matter of nine years the American Government 

 has worked miracles, and I am certain that my fellow-delegates will 

 join with me in heartily congratulating the Bureau of Health, and 

 especially Doctor Heiser, on their great work. 



Dr. J. M. Atkinson, principal medical officer, Hongkong, delegate 

 from the Government of Hongkong. — I have much pleasure in seconding 

 Doctor Highet's remarks congratulating Doctor Heiser on what has 

 already been accomplished by the Bureau of Health. As far as I am 

 aware, there is as yet no other example in the history of the world 

 where such effectual measures have been taken to improve the sanitary 

 condition of the subject native races those as which have been undertaken 

 by the American Government since its occupation of these Islands, a 

 period of less than twelve years. 



To protect 6,000,000 people out of a total of 9,000,000 from smallpox 

 is a wonderful piece of work. With regard to the city of Manila and 

 its freedom from malarial fever, it appears to me that this freedom may 

 be only temporary, as were the Filipinos to become infected with malaria, 

 all the white people living in the city would be liable to infection. Mos- 

 quitoes capable of transmitting the malarial parasite are already present 

 and extensive areas of swampy land exist. 



I would suggest the advisability of gradually rilling in these swamps 

 as funds permit, as it is impossible effectually to drain them, since much 

 of the area is below the level of the high tides prevailing. The filled-in 

 swamps could be utilized for building sites, etc., and thus prove remuner- 

 ative. 



DISCUSSION ON THE PAPER, "THE PARTHENOGENESIS OF 

 THE FEMALE CRESCENT BODY," BY DOCTOR NEEB. 



Dr. E. R. Stitt, surgeon, United States Navy, associate professor of 

 medical zoology, Philippine Medical School. — I have frequently, upon 

 questioning others, found that they had never observed the phenomenon 

 of parthenogenesis in connection with the benign tertian parasite, the 

 species upon which Schaudinn made his observations.
