For a number of years he acted as one of the Secretaries 

 of the Geological Section of the Association, and as Recorder 

 since the year 1907. 



Mr. Lomas was a Fellow of the Geological Society, and in 

 1897 was awarded the Lyell Fund ; a member of the Geologists' 

 Association, and of the Yorkshire Geological Society. 



By his untimely death, not only has Geology lost an ener- 

 getic and brilhant worker, but many will feel with the writer, 

 that they have lost a friend whose cheerful good nature and 

 unfailing courtesy rendered him dear to all who had the privilege 

 of his acquaintance.

Shells in British Barrows. — Referring to my notes in 

 ' The Naturalist ' for December, Mr. A. S. Kennard, F.G.S., has 

 written to me expressing surprise that Helicella cantiana is 

 found among the other shells from Birdsall Brow. He says : — 

 ' We have always looked upon it as a modern [i.e., Roman or 

 post Roman) introduction. I fancy that it must be an acci- 

 dental occurrence. It is certainly always absent from pre- 

 Roman beds.' The presence of this later species in a neigh- 

 bouring barrow (67 Birdsall Brow) to that (65 Birdsall Brow), 

 in which Caecilianella acicula is found, further confirms the 

 view that these shells may have got into the barrows in other 

 ways, at a later date than the interment, and that they may 

 not be contemporaneous with the human remains. I do not 

 wish to press this unduly, but think due weight should be 

 given to their presence in coming to a definite conclusion on 

 the point of the age of the shells in the barrows. — E. P.
