18 REPORT 1875. 



api^aratus employed in the obserratious has been thoroughly cleaned and put 

 in order. 



In answer to an application addressed to the director of the School of 

 Mines at Schemuitz, in Hungary, a letter was received, under date Novem- 

 ber 1873, from Herr E. Poschl, Counsellor of Mines, and Professor _ of 

 Mining Mechanics and DraAvings (the director being absent), requesting 

 that thermometers might be sent. A second letter was received from the 

 same gentleman, dated December 26, 1873, acknowledging the safe arrival 

 of the thermometers (one a Negretti maximum protected, the other non- 

 registering and unprotected), and stating that the observations would at 

 once be commenced, under the direction of a joint committee of professors of 

 the Mining Academy and members of the Directory of Mines. 



Professor Henry, of the Smithsonian Institution, Washington, wrote, 

 under date February 3, 1874 : — " You wiU oblige us by sending us three 

 sets of guarded registering thermometers, suitable for observations of tem- 

 perature of artesian wells of a diameter of 3 inches. We learn that there 

 are in the vicinity of Chicago sixty wells varying from 500 feet to 1500 

 feet in depth, included within an area of six miles square. Their elevation 

 above the level of Lake Michigan, as well as the quahty of the water they 

 furnish, are very nearly alike. We shall send a set of these instruments to 

 a trustworthy engineer of Chicago." . . . 



In accordance with this request, three protected maximum thermometers 

 have been sent. 



No successful observation has yet been made in the Sub-Wealden bore 

 nor in the well at Witham. No report has been received fi-om Harwich, 

 from Anziu, from the Hoosac Tunnel, nor from the Mont-Cenis Tunnel. 



As regards the St.-Gothard Tunnel, the absence of Professor Ansted has 

 hitherto delayed the caiTying out of the resolution adopted by the General 

 Committee last year (see Report for 1873, p. Iviii, last paragraph) ; but 

 action will probably be taken very speedily. 



Report of the Committee, consisting of Professor Huxley, F.R.S., 

 P. L. ScLATER, F.R.S., F. M. Balfour, J. Gwyn Jeffreys, F.R.S., 

 Dr. M. Foster, F.R.S., E. Ray Lankester, F.R.S., and A. G. 

 Dew-Smith {Secretary), on the Zoological Station at Naples. 



At the Bradford Meeting of the Association the Committee on Zoological 

 Stations was able to report (see Association Reports, 1873, page 408) that 

 tlie buHding of the Zoological Station at Naples had been completed ; but it was 

 naturally obliged rather to describe the arrangements made for carrying out 

 the objects of the Station than to dwell on the work which had been actually 

 done. 



The present Committee, however, can now congratulate the Association 

 that, during the two years which have elapsed since the Bradford Meeting, a 

 scientific undertaking of cosmopolitan character, hi which the Association 

 has taken a lively interest, and which it has in so many ways assisted, has 

 proved an undeniable, indeed it might be said a brilliant success. The actual
