HULL (Chairman), Sir DOUGLAS GALTON, Messrs. J. GLAISHER, PERCY KENDALL, Professor G. A. LEBOUR, Messrs. E. B. MARTEN, G. H. MORTON, Professor PRESTWICH, Messrs. I. ROBERTS, THOS. S. STOOKE, G. J. SYMONS, W. TOPLEY, C. TYLDEN-WRIGHT, E. WETHERED, W. WHITAKER, and C. E. DE RANCE (Secretary). (Drawn up by C. E. DE RANCE.) THE reporter has made good progress with the digest of the previous nineteen reports, which will be ready for publication this year, giving the details grouped in geological formations and counties. The reporter, through unavoidable circumstances, is unable to be present this year, and is anxious to point out that not only has the Cardiff Naturalists' Society sent a valuable contribution, but several other societies federated to the British Association intend to furnish information; this being the case, he ventures to point out that it appears desirable to continue the work of your Committee, and that it is evident that if the work entrusted to them in 1874 be terminated in 1894 it will be continued by the federated societies, but the details of sections and analyses will be scattered over many publications and will not be of general use and access to engineers and sanitarians, and the results obtained will be published under various modes and conditions not admitting of common reference, as is the case in the reports emanating from your Committee. The Committee would therefore venture to suggest that, as valuable information can still be obtained through the agency of local societies, they be reappointed without grant. Your Committee have to deplore the death of one of their original members, Mr. Wm. Pengelly, F.R.S., who contributed most valuable information in the early days of the investigation, and throughout has taken an active interest in the work. |
