A Coming Investigation of
 the Great SCOurge
ITS SCIENTIFIC INTEREST
A Meeting to Be Held in Washineton in May by the National Association for the Study and Prevention or Tuberculosis.

Washington. D. c. April 2s.-Gr-zs scientific interest attaches to the com ing annual meeting of the Nationz4 Association for the Study and Proven tion Of Tuberculosis. which win take place in this city on the 18th and Isth of May So widespread and so deadly has become this disease that ft fs now generally referred to as the white plague" Surgeon General Ivyruan or the U. s. marine hospital service. has received numerous letters from health officers on this subject. especially on that branch Of it which relates Co the spread of the disease by travellers ou the various railroads Dr. S- J. Crum- hine, secretary of the Kansas state board of health, thus writes.
 The geographical position or this state is such, lying immediately east oE the health resorts of the Rocky noun tains, that it could probably be assert ed that there is scarcely a rranscontir- ental train going west the year round that does not carry its one or more passengers afflicted with tuberculosls. seeking the life giving and healthfuf resorts of Colorado New Mexico ana Arizona. With little or no convenience for the proper disposal Of the exp=cto-
 
 evident that these cars are in a chronic state of infection Time and again | have personally observed a consumn- tive in day coach where there were no cuspidors provided. coughing and expectorating upon the floor. These people being of low vitality and afraid of draughts and cool air while traveling require that the coaches be closed which adds to the danger Of infection to their fellow passengers The con stant vibration of an ordinary railway coach is free, and which is admittedly the carrier of the bacillus or tubercu- losis"
 Dr. H NJ Bracken of St Paul. sec retaTy of the Minnesota state board of health, has been assigned Co read a paper before the association on -In- lection in Transportation and as pr Bracl1en has made an exhaustive study of the subject, he is expected tn present data of the greatest iunportance In connection with the above meeting. Dr. Wyinan has called a meeting of the ex- ecutive officers of the state boards or health for May IS.
 It is regarded by the scientists who expect to be in attendance as especiaI- iy fortunate that while the meeting IS in progress they will have unusual la cilities for studying the latest improve ments in the ventilation and sanitation or railway passenger cars Simultane- ous with the meetings of the health specialists will be the meeting of the International Railway Congress ,xIrh its great exhibition of cars and railway appliances. for which congress has granted the use of the white lot In the exhibit will be many devices for the ventilation and heating or passenger cars, matter that is just now being widely discussed by health boards. scientific men, and railroad authori- ties. Numerous tests will be made in the presence and under the direction of distinguished health officers from different parts of the country The tests wil consist of a series Of experi- ments to demonstrate how quickly and how completely the air in passeug-r coaches can be changed. it being the aI- ready expressed opinion of scientific men that public health demands an en- tire change of air at least once tu every six minutes.
