MICROSCOPY AT MANCHKSTKR. 



The Annual Report and Transactions of the Manchester 

 Microscopical Society' have just been recei\ed, and contain 

 several items of interest to our readers. Among-st these are 

 the President's Address, * Precious Corals,' by Prof. S. J. 

 Hickson ; 'Notes on Acan/hocvs/is per/yana,'' by J. \i. Lord; 

 'The Microscopic Structure of Stems,' by C. Turner; and 

 'Animal Colouration,' by Mark L. Sykes. The latter is illus- 

 trated by plates of lepidoptera illustratinj^ simulation of 

 environment. By the permission of the society we are able 

 to reproduce these (plates XXIX., XXX.), upon which are no 

 fewer than twenty species of butterflies. 



GKOCIRAPHV AT MA.NCHESTER. 



In the 'Journal of the Manchester Geographical Society,' 

 Vol. 2 1., Nos. 7 to 12, Mr. C. E. Moss has an interesting' paper 

 on the botanical g"eojj^raphy of a Pennine stream. In this the 

 author deals with the Alpine associations, subalpine associa- 

 tions, woodland associations, lowland alluvial formations, 

 maritime formations, and the region of cultivation. It is illus- 

 trated by several photog^raphs showing- characteristic botanical 

 features. 



EAST YORKSHIRE AM) ITS WATER SIPPLY. 

 The Geolog-ical Survey continues to publish its useful 

 memoirs dealing- with the water supply of definite areas. The 

 most recent deals with East \'orkshire,* and has been prepared 

 by Mr. C. Fox-Strang-ways, with contributions by Dr. H. R. 

 Mill. There is a carefully prepared introductory chapter dealing- 

 with the geology of the area so far as it relates to the water 

 supply ; Dr. Mill follows with notes on the Rainfall, which are 

 illustrated by a useful map. The greater part of the \-olume, 

 however, is occupied by details of well sinking-s and boring-s in 

 the N'ale of Pickering, the \'ale of York, the Jurassic and Creta- 

 ceous Hills, and the Holderness plain. There are analyses of 

 water, an extensive bibliography, and a good index. Just now, 

 when the water supply of this district is ' in the air,' so to speak, 

 the recenlh issued menioir should be of \alue.
