action of different radiations on organisms. The 

 following topics have thus far been proposed as 

 being suitable for special reports: (1) Action of 

 the X-rays and of radioactivity on cellular struc- 

 ture; (2) action of radiations in general on the 

 development of plants. 



B. Medical Radiology. — Radio-diagnosis. This 

 schedule is to include all the medical applications 

 ot radioscopy and radiography. Three topics have 

 been admitted up to the present time as probably 

 suitable for reports: (1) Rapid radiography; in- 

 stantaneous radiography; (2) study of the stom- 

 ach and of the intestines, from the physiologic 

 and the pathologic points of view; (3) endo- 

 diascopy. 



C. Radio-therapeutics. — Under this schedule will 

 be included all reports appertaining to the treat- 

 ment of diseases by radiation, (a) X-rays; (6) 

 radioactivity; (c) other radiations. The follow- 

 ing topics have also been provisionally considered: 

 (1) The filtration of rays (X-rays and radio- 

 activity) ; (2) radioactive medicines; (.3) treat- 

 ment of tumors by radium; (4) present state of 

 photo-therapeutics and its different methods. 



The specifications of the present program 

 are merely provisional; they are to be con- 

 siderably altered in the final revision. A spe- 

 cial exposition of all apparatus and appliances 

 comprehended under the present subject will 

 be annexed to the congress. 



Attention may finally be directed to certain 

 rules of the congress. 



Art. 2. — The following persons will be members 

 of the congress and they alone will receive the 

 publications: (1) the delegates of the Belgian 

 public administration and the delegates of foreign 

 governments; (2) donors, including those persons 

 who have given a sum of 100 francs or more; (3) 

 all persons who have contributed the sum of 20 

 francs. The wives of members as well as their 

 unmarried children may be registered as associates 

 at a fee of 10 francs. The same charge will be 

 made to students. 



Art. 3. — The members of the congress and their 

 associates will alone have the right to participate 

 in its scientific transactions, to take part in its 

 excursions, etc. 



All members will receive the publications in 

 full, both before and after the session of the 

 congress. They will be entitled to enter the 

 exposition at Brussels gratuitously on present- 

 ing their cards. 



It is particularly requested that all com- 

 munications of a financial nature (member- 

 ship fees, etc.) be addressed directly to the 

 general secretary of the committee on organ- 

 ization, M. Daniel, No. 1 Eue de la Prevote, 

 Brussels, Belgium. 



By order of the American Committee.

WINTER MEETING OF THE AMERICAN 

 CHEMICAL SOCIETY 



The winter meeting of the society will be 

 held in Boston, Mass., December 28 to 31 in- 

 clusive, in affiliation with the American 

 Association for the Advancement of Science, 

 whose associated societies meet throughout 

 the week. 



Railroad rates will probably be secured as 

 usual and as there is to be a large gathering 

 of scientists in Boston this winter, there will 

 undoubtedly be a sufficient number of persons 

 present to make these reduced'rates available. 



The society will meet in six divisions and 

 two sections under the guidance of the officers 

 enumerated below.
