Obituary— William E. Corfield, M.D., F.G.S. 479 



anywhere stated that tourmaline could only be formed in the way 

 which I had described in that particular rock. 



Yet more, in regard to the occurrence of magnetite in cubes. With 

 such very minute grains mistakes are more than possible, but I still 

 think that I detect the solid angles of cubes as well as of octahedra, 

 and at any rate submit that this reference to my statement is 

 misleading — " So far as I am aware [this is] the only record of 

 the occurrence of magnetite in cubes in Great Britain " — for I had 

 stated distinctly that the rock which I was describing was not in 

 its natural condition, but, as I said, a basalt which had been com- 

 pletely melted by Messrs. Chance. That fact ought not to have 

 been suppressed. T. G. Bonnky. 



BRITISH GEOLOGICAL PHOTOGRAPHS. 



Sir, — With reference to your most kindly article in the GEOLOGiOAii 

 Magazink for September, I should like to be allowed to say a few 

 woi'ds, in order to avoid the possibility of misunderstanding. 



The published series of " British Geological Photographs " consists 

 of platinotypes (mounted or unmounted) or lantern-slides, accom- 

 panied by letterpress, and is issued only to those who undertake 

 to subscribe for the three issues (at least 20 photographs each) 

 of which the publication consists. Sets cannot be broken, and it 

 is not permissible to subscribe for one issue out of the three. 



I have room at present for about 20 new subscribers for the three 

 issues, and for 50 new subscribers my Committee would consider 

 the advisability of reissuing the whole series. 



The third issue, which I hope to publish within this year, will 

 complete the publication ; but the Committee are contemplating 

 the possibility of issuing a supplementary series on the same terms. 

 Such a series would endeavour to fill up gaps in the first series, 

 would illustrate important phenomena a little more fully, and would 

 also include the more uncommon features and phenomena. A certain 

 number of subscribers' names have been received for this supple- 

 mentary series, but not yet enough to warrant publication. For the 

 descriptions which accompany the photographs and add so much 

 to their value for scientific and teaching purposes, the Committee are 

 indebted to a number of geologists, many of whom are not members 

 of the Geological Photographs Committee. W. W. Watts.

Wb regret to record the death at Marstrand, Sweden, of 

 Professor William Henry Corfield, sanitary adviser to His Majesty's 

 Office of Works, one of our leading authorities on Sanitary Science, 

 and one who brought a sound knowledge of geological science to 

 bear on that subject. He was born in 1843, and was educated at
