ing a great network of seismoscopes with a few seismograpTis in suitable 

 localities, and resnlts of value would by tbis means be, in all probability, 

 obtained. These results would be valuable in proportion as well-equipped 

 seismometrical observing stations were numerous. The expense must in 

 any case be considerable in the aggregate, but need not be great in in- 

 dividual cases. A sufficiently good seismoscope might be had for about 

 21., a seismograph for 14Z. to 15L, and the cost of keeping them in order 

 ■would not be great. He hoped the Delegates present would help in estab- 

 lishing such a network of observing stations all over the country, and 

 he would be happy to communicate with anyone interested in the subject. 

 Professor Ewing, in response to the Chairman, said that from his ex- 

 perience of earth-tremor observations in Japan he could concur in the 

 remarks of Professor Lebour. To investigate fully the character of the 

 motion, even at one station, required delicate and costly apparatus, and 

 the cost was greatly increased when it was attempted to bring a number 

 of stations into correspondence so as to determine the motion over a large 

 area. It was possible, however, to record the fact that a tremor had 

 occurred, and even to learn something of its character by means of in- 

 expensive seismoscopes ; and it certainly seemed to him that no bodies 

 could more appropriately undertake that work than the local Societies 

 represented at the Conference acting in conjunction with a Committee 

 of the Association. From recent observations it appeared probable that 

 tremors would be found wherever they were tested for with sufficient 

 delicacy, so that a Society undertaking the search was not likely to be 

 disappointed. 



At the second Conference the chair was taken by Professor Boyd 

 Dawkins, P.R.S., who was succeeded by Mr. W". Topley, F.G.S., the 

 Corresponding Societies Committee being farther represented by Mr. 

 G. J. Symons, F.R.S., Dr. Garson, Mr. William White, and Professor U. 

 Meldola, F.R.S., Secretary. 



The Chairman invited discussion on the recommendations received 

 from the various Sections. 



Section A, 



Temperature Variation in Lakes, Rivers, and Estuaries. — The following 

 resolution was forwarded to the Secretary of the Conference by the 

 Secretary of this Section : — 



' That Mr. John Murray, Professor Cbrystal, Dr. A. Buchan, Rev. 

 C. J. Steward, Hon. R. Abercromby, Mr. J. Y. Buchanan, Mr. David 

 Cunningham, Mr. Isaac Roberts, Dr. H. R. Mill, and Professor Fitz- 

 gerald be appointed a Committee to arrange for an investigation of the 

 seasonal variations of temperature in lakes, rivers, and estuaries in 

 various parts of the United Kingdom in co-operation with the local 

 Societies represented at the Association ; and that Mr. John Murray be 

 Secretary.' 



Dr. H. R. Mill, as representing this Committee, stated that the 

 question proposed had not been fully worked out, but that the few- 

 observations made showed relations of a very interesting kind. As a 

 branch of meteorology, this research was particularly promising, and was 

 one in which the co-operation of local Societies would be valuable. He 

 proposed that the Societies situated in the neighbourhood of rivers and 

 estuaries which were willing to undertake this work should appoint some
