world, for geography included all the sections of the British 

 Association. 



Mining Institutes. — Prof. Lebour said the Committee on 

 Explosives was now in full working order. They had taken up the 

 work of examining the properties of so-called flameless explosives, 

 the main object of which was a philanthropic one. They wished to 

 avoid the possibility of a flame being projected from a blown-out 

 shot in an atmosphere laden with flying particles of dust. If coal- 

 dust was there, it would carry an explosive further than it would 

 otherwise go, and change what might be a comparatively trifling 

 accident into a catastrophe of a very destructive character. There 

 was another Committee, consisting of the Mining Institutions of the 

 North of England, of the Midlands, and of South Wales, which had 

 joined together for the purpose of carrying out a series of experi- 

 ments with fans. The reports of that joint committee were of very 

 great value to engineers, not only connected with mines, but with 

 other works requiring artificial ventilation. They would be exceed- 

 ingly glad to receive any hints or information which would tend to 

 the better securing of the objects he had mentioned. 



Tumuli. — Dr. Garson, who represented the Anthropological 

 Section, requested that before any burrow or tumulus were opened, 

 a paper containing a series of directions should be obtained from 

 the Anthropological Institute, Hanover Square, London, in order 

 that no object of interest should be overlooked. 



Status of Delegates. — Prof. Lebour proposed a resolution to 

 the effect that the relation of delegates to the Sectional Committees, 

 as at present constituted, was unsatisfactory, and should be recon- 

 sidered by the Corresponding Societies' Committee. Your delegate 

 seconded the motion, which was carried, and the proceedings closed. 



At the meeting of the General Committee, held on Monday, the 

 1 6th, it was agreed that the next meeting of the Association should 

 commence at Leeds, on Wednesday, the 3rd of September, 1890, 

 under the presidency of Sir F. A. Abel, C.B., D.C.L., F.R.S. 



The Report of the Committee on the Migration of Birds, of which 

 Mr. John Cordeaux is secretary, which was appointed at Bath to make 

 a digest of the observations on Migration of Birds at Lighthouses and 

 Lightvessels, which have been carried on during the past nine years, 

 was read in the Biological Section by your delegate. The Committee 

 reported that one of their number, Mr. W. Eagle Clarke, had under- 

 taken to prepare the digest of the observations. They felt that no 

 apology was necessary for the non-completion of the digest this year, 

 and they respectfully solicited their re-appointment with the same 

 object as before.
