130 REPORTS ON THE STATE OE SCIENCE. 



Prince of Monaco, who will publish it from the Oceanographical 

 Institute in Monaco. A photograph of that map has been presented 

 to the British Association as a report of the work. 



A second reduction on the same scale (1 : 100,000) is being pre- 

 pared in feet and fathoms for publication in Britain. 



Beports of the field work in connection with the map have already 

 been given at the meetings in Dublin and Sheffield. 



Gaseous Explosions. — Interim Report of the Committee, consisting of 

 Sir W. H. Preece (Chairman), Mr. Dugald Clerk and Professor 

 Bertram Hopkinson (Joint Secretaries), Professors Bone, Bur- 

 stall, Callendar, Coker, Dalby, and Dixon, Drs. Glazebrook 

 and Harker, Professors Petavel, Smithells, and Watson, Lieut.- 

 Col. Holden, Captain Sankey, Mr. D. L. Chapman, and Mr. H. 

 E. Wimperis, appointed for the Investigation of Gaseous Explosions, 

 with Special Reference to Temperature. 



During the session 1910-11 the work of the Committee has been 

 continued, but from various circumstances — partly break-down of 

 apparatus and partly pressure upon the time of various investigators — 

 only two Notes have been read. Three meetings have been held, two 

 at Mr. Dugald Clerk's rooms at Lincoln's Inn Fields and one at the 

 Finsbury Technical College, Leonard Street, City Boad, London, 

 E.C. The meetings have been excellently attended and two Notes 

 have been presented and discussed, viz., No. 19, on ' The Volumetric 

 Heat of Carbonic Acid and Air up to 1000° C.,' by Dugald Clerk, and 

 No. 20, on ' The Cyclical Changes of Temperature in a Gas-Engine 

 Cylinder at and near the Walls, ' by Professor E. G. Coker. 



A great deal of other work is in hand, which will be included in a 

 full report to be given next year. 



The Organisation of Anthropometric Investigation in the British Isles. — 

 Report of the Committee, consisting of Professor Arthur Thomson 

 (Chairman), Mr. J. Gray (Secretary), and Dr. F. C. Shrubsall. 



The Committee, through lack of funds, have not been able themselves

 Isles. 



It is however satisfactory to note that the scheme embodied in 

 their 1908 report, which is published by the Boyal Anthropological 

 Institute, is being widely adopted throughout the British Empire and 

 elsewhere. 



The Australian Association for the Advancement of Science has 

 resolved that the scheme of this Committee be adopted in all anthropo- 

 metric survey work carried out in Australia. At the present time an 

 extensive and very complete survey of the school children of Victoria
