It opens with ten pages of introduction on the nature of earth- 

 quakes in general and their relation to Japan, with brief mention 

 of the salient incidents of the recent disaster, from which some of 

 the statements above are taken. This is followed by thirty plates, 

 varying a little in size, but mostly about 32 cm X 21 - 5 cm and each 

 plate is accompanied by a brief description. These plates give 

 very impressive illustrations of the destruction caused by the 

 earthquake. ' 



2. Congress of Mathematicians and Astronomers. — In con- 

 nection with the Exposition to be held at Chicago in 1893, a 

 " World's Congress Auxiliary " has been formed for the purpose 

 of organizing a series of Congresses or Conventions to be held 

 during the progress of the Exposition, which will bring together 

 the leading scholars of the world for the mutual interchange of 

 ideas on topics bearing on human progress. 



As a part of this general plan a preliminary address has been 

 recently issued from the division of Mathematics and Astronomy, 

 of which Prof. George W. Hough is chairman, inviting the coopera- 

 tion of all persons and societies interested in the department of 

 physical science. Three chapters are proposed : I in Pure Math- 

 ematics, II in Astronomy, and III in Astro-physics. A series of 

 topics is given in the circular by the committee, which are sug- 

 gested for consideration. Advice and suggestions are desired 

 as to the general conduct of the convention, and in particular as 

 to the scientific questions to be discussed, and persons to present 

 them. The suggestions and recommendations invited will be 

 used in the formation of the program for the Congress. 



The Chairmen of the Special Committees of the several chapters 

 under the charge of the General Committee, are as follows : 



Pure Mathematics, Prof. E. II. Moore, Chicago University, 

 Chicago, 111. 



Astronomy, Prof. G. W. Hough, Dearborn Observatory, North- 

 western University, Evanston, 111. (who is also general chairman). 



Astro- Physics, Prof. George E. Hale, Kenwood Astro-Physical 

 Observatory, Chicago, 111. 



3. American Association. — The 41st meeting of the American 

 Association for the Advancement of Science will be held in 

 August next, commencing with Wednesday, the 17th, at Roch- 

 ester, New York. All abstracts of papers should be sent to the 

 Permanent Secretary, F. W. Putnam, Salem, Mass., until Aug. 

 7th, and after that time, to Powers' Hotel, Rochester, the hotel 

 headquarters of the Association. The President of the meeting 

 is Prof. Joseph LeConte, of Berkeley, California. The Local 

 Secretary, Prof. H. L. Fairchild of the University of Rochester 

 will give information, if desired, with regard to local arrange- 

 ments, hotels, railway rates, etc. The Register will be opened in 

 the University of Rochester on the 15th of August, and the 

 meetings will be held in the buildings of the University. 



The Geological Society of America will hold its August meet- 

 ing at the same place on Monday and Tuesday, Aug. 15 and 16,
