inhabitants exposed on one of the banks of the river. It still re- 

 tained its skin and wool, and even the tusks, for they were so 

 firmly fixed that the Samoyedes had been unable to withdraw them. 

 Mr Nossilov did not himself remove the mammoth, but he suggests 

 that here is an excellent opportunity for some museum or university 

 of his country to procure a mammoth in a complete state of pre- 

 servation. Even the famous mammoth skeleton in the Academy of 

 Sciences at St Petersburg is very far from perfect. Many parts 

 are restored in wood, and the tusks do not belong to the same 

 animal as the other portion of the skeleton. 



G-EOLOGicAL Photographs 



The Eighth Report of the British Association Committeee for the 

 collection of photographs of geological interest in the United King- 

 dom, just issued, details those which had been received by the com- 

 mittee during 1896-97. The collection, which is stored at 28 

 Jermyn Street, and which is accessible to students on applica- 

 tion, now numbers 1751 items. No less than 364 new pictures 

 were received during the year, among them being a series from the 

 Wealden area, from ISTottingham, North Staffordshire, the Sgurr of 

 Eigg, Yorkshire Caves, County Dublin, Yorkshire, the Isle of Man, 

 Devonshire, Isle of Wight, Charnwood, Yorkshire Dales, and 

 North Wales. The most valuable series came from that exquisite 

 artist, Mr R. Welch, of P)elfast, who contributed no less than 100 

 platinotypes of wonderful excellence of Irish geology. It is difficult 

 to over-estimate the value and utility of such a collection, and the 

 committee state that several of the features preserved have now 

 disappeared. We would especially urge all those who follow geo- 

 logical nature with a camera to assist this committee by forwarding 

 platinotypes unmounted to the secretary, Mr W. W. Watts, of the 

 Mason College, Birmingham, and it is to be remembered that a 

 photograph showing geological features, even if not specially taken 

 from a geological point of view, may be of great value as a record 

 for seolosists and others. 



Arrangement of Chambers in Foi;a.minifera 



A POSSIBLE explanation of the quinqueloculine arrangement of the 

 chambers in the young of the microspheric forms of Triloculina and 

 Biloculina is offered by Mr J. J. Lister in a paper recently read 

 before the Cambridge Philosophical Society. In the megalospheric 

 forms of these genera the arrangement is very simple, is followed 

 from the beginning, and is disposed on either side of an axis, the 

 median plane which divides any single chamber symmetrically being
