Causes Will Be Studied and Means Provided for Its Prevention.

WASHINGTON. D. C.. Sept 2e-As the result of a conference held in this city between Surgeon General Rupert Blue and Dr. Sanbon, the famous Eng lish pellagra expert who visited the United States recently on his way to 'the West Indies where he vii make further investigations into the nature causes aud prevalence of the dreaded disease, invitations will probably be sent out in the near future for holding at some suitable point fin this country next year an international pellagra conference The details of the plan have not yet been arranged, nor has the place for holding the conference as yet been selected or the time for the conference fixed.
 Dr Louis Sanbon, who is admitted to be the greatest living authority on the subject of pellagra, is now on his third field expedition under the ans pices of the British Pellagra Investi- gation committee and will remain for some time in the West Indies to make a thorough study of the diseases which claims thousands of victims in the British colonial possessions in tho Carribean Sea. Recognizing tn egreat danger from the strange disease, which has found firm foothold in the South of the United States and with which, it is estimated, some 5O,0O0 persons are afflicted in this country Dr. Sanbon made the suggestion dur ing his recent visit in Washington to hold an international conference for the purpose of discussing the dis ease in it's various phases, it's causes and means for it's prevention and cure.
 The cause of pellagra was long held to be the consumption of damaged maize. since it is in maiZc-eating coun- tries that the disease prevails. It is due to the careful investigations and the genius of pr. Louis Sanbon that this theory has been practically aban- ioned by scientists in favor of Dr. Sanbon's theory that pellagTa, like malaria. yellow fever. filiaria, and many other tropical diseases. is caused by an infection conveyed oy an insect--a simulium, or sand fly inst as malaria is now known to be conveyed by the anopheles mosquito
 Dr. Sanbon is only forty-one years old, yet he is recognized throughout the world as one of the greatest au- thorities or tropical diseases. He was born in Italy of a French father and an English mother Graduating with honors in medicine from the Univer- sity of Naples in 1891, he became an assistant surgeon in the Italion army Soon. however, on account of his scientific attainments and his linguist- ic' ability he was sent to various coun- tries on scientific missions
 In 1897 Ee went to England, where he soon attracted the attention of Sir Patrick Manson by an article on ac- climation. Later he was appointed to the chair of parasitology iE the Lon Jon School of Tropical Medicine It was in 1897 that Sanbou first publicly enunciated the theory that not the climate renders the tropics uninhab- itabie to the white man, but the trop- ical parasite infections. Tn 1900 he proved beyond reasonable doubt that malarial fever is produced through the stiEg of the infected anopheles mosquito and that protection from the sting gives immunity He proved his theory by living for several months in a screened hut in the most un- healthy portion of the fever infected ENblAdu Adlllntslia.
 Twice Dr. Sanbon was ennt to Italy to investigate the Pe1'agr3 disease and incidentally he visited. in 1911 several peIIagra districts in Roumania, Aus tria. Hungary. Spain and France, col 1ecting valuable material and making numerous observations confirming his theories concerning the nature of the disease and it's direct cause. His Ob- servations clearly established the sus- pected connection between the disease ana the bites by an insect of the Simulldes family.
 While the efforts Of Dr. Sanbon have heen primarily directed toward posi- lively establishing his theory concern ing the origin of the infection by the bite of certain insects, he Is carefully studying ways and means of prevent, ing the spread fthe disease by proper protection from the infected insects and. eventually by the extermination of the disease-bearing pests. The eHor- nous number of pellagra eases in the United States, especially in certain portions of the South makes the sup rression o fthe disease and it's imme- diate cause a matter Of the greatest importance to this country and it Is expected tbat the plan for holding n International pellagra conference will meet with the warm support of the
