C verticornis, C. poligniacus, C. Savinii, etc., and the findingof any one 

 of these forms in the Ffynon Beuno deposit would be strong evidence 

 in favour of its Pre-Grlacial age ; but not one of them has been found. 

 With regard to the stratigraphical evidence of the age of this 

 deposit, I have nothing to say : but the mammalian fauna would 

 certainly lead one to assign to it a Pleistocene and not a Pre-Glacial 

 origin. E. T. Newton. 



PHOSPHATIC NODULES OF THE SALT EANGE, INDIA. 

 Sib, — Dr. H. Warth, of the Indian Civil Service, writes from 

 DehraDun, under date 17th Nov. 1886, referring to certain nodules of 

 Phosphate of Lime, which he found in overlying shales associated 

 with the Salt Eange Coal at the localities of Pid, Dandot, etc. He 

 speaks of these phosphatic nodules as being " nearly equal in purity" 

 to the "bed" of phosphate of lime at Mussoorie Hill-station, which, 

 so far as I am aware, he was the first to notice in this connexion ; 

 having sent me some samples from the locality nearly a year ago. 



Prom this locality, it would seem some inferior specimens had 

 been sent home for examination, by order of Government, the 

 London results giving only one-ninth of the quantity of phosphoric 

 acid found by Dr. Warth's own analysis of better specimens. As to 

 the Salt Range nodules which he has also analyzed, I extract from 

 his letter, viz. : — 



" Analysis of phosphatic nodules with hemispherical pores all over the surface 

 from the Pid, Dandose Colliery, etc., in the Eastern Salt Eange; scattered in the 

 shales which overlie the Eocene Coal Seam, and sometimes replacing shells.

 The importance of the occurrence of the valuable mineral phos- 

 phate of lime in India leads to the hope that Government will take 

 steps to have the Himalayan limestone zones specially explored with 

 regard to such deposits and to their worth. A. B. Wynne.

Born 30 Junb, 1841 ; Died 24 December, 1886. 



Wb have to record with deep regret the loss of a valued friend 

 and sometime colleague in the Editorship of this Magazine (1865), 

 who has passed away at the close of the old year whilst still in the 

 prime of life, with the hope of at least many more years of work 

 before him. 



Henry Michael Jenkins was born at Fairwater Mills, Ely, near 

 Llandaff. His father, Mr. John. Jenkins, an energetic and clear-
