place, unless it be in Central Mull — is familiar to every student 

 of our Tertiary igneous rocks. Whatever be its significance, it 

 disposes effectually of Mr. Craig's argument. 



If, without discourtesy, I may play the mentor in my turn, I 

 would hint in conclusion that a little knowledge, when joined to 

 a large measure of assurance, is a dangerous thing.

HAEMATITE IN SOUTH WALES. 



Sir, — Allow me to correct a misstatement, serious from the 

 economic standjDoint, which is contained in the review of " The 

 Haematites of the Forest of Dean and South Wales " (Memoirs of 

 the Geological Survey : Special Reports on the Mineral Resources 

 of Great Britain, vol. x) published in the January number of your 

 journal. 



The reviewer states that " the author sees no hope for the resusci- 

 tation of the mines under j) resent conditions ". On the contrary, 

 the memoir under review describes the haematite-field of South Wales 

 as a promising area for develojiment. Thus : " In the haematite- 

 field of South Wales . . . recent years have witnessed a successful 

 revival of iron-mining, and the ore-fields give considerable promise 

 for future development " (p. 2) ; and again : "In view of the high 

 grade of the ore, the comparatively large tracts of undeveloped 

 ground, and the successful mining at Llanharry in recent years, 

 it appears not improbable that the district will produce haematite on 

 a larger scale in the future than it has done in the past " (p. 65). 



As a matter of interest, I may add that new explorations for 

 haematite in the Llanharry district, undoubtedly stimulated by the 

 official geological investigation of the area, have already commenced. 



Yours faithfully,

OBITUARY. 



Henry Charles Beasley. 



The late Henry C. Beasley, who died at Liverpool on December 14, 

 1919, at the ripe age of 83, was best known to geologists for his work 

 in connexion with the Triassic footprints, especially those found 

 in the Keuper beds at Storeton, Cheshire, and other quarries in the 

 Liverpool district. He published a number of papers in the Pro- 

 ceedings of the Liverpool Geological Society recording his observa- 

 tions, and as Secretary of the British Association Committee for
