but Prof. Geikie considers that the balance of proof is decidedly in 

 favour of tbe volcanic origin of the rock. 



Cole's Studies in Microscopical Science. — These have now 

 reached the 40th number, and fully support the high praise which has 

 been bestowed upon them in every direction, both for the informa- 

 tion contained in the text, the beauty of the coloured illustrations, 

 and the excellence of the accompanying slides. Microscopists have 

 long lamented that it was not possible to obtain a guide to the slides 

 sold, so that the points of interest illustrated could be intelligently 

 appreciated. Now that this is provided, it is to be hoped that they 

 will bear in mind that something more is required than " moral " 

 support in order to ensure a continuation of the series. So many 

 useful ventures have failed through microscopists trusting to their 

 neighbours to provide substantial support, that it is necessary to urge 

 that every one who believes in the value of Mr. Cole's enterprise will 

 himself subscribe to it. No more profitable return can, we are sure, 

 be found for the small outlay required.
