GEOLOGICAL SURVEY OF INDIA. 263 



The other volumes issued during the year (XX. and XXII.) 

 contain the memoirs by Messrs. Blanford, Foote, and Lydekker, 

 already referred to. 



The Records for the year (Vol. XVI.) embrace 24 articles of varied 

 interest with numerous maps and plates. Of the " Palasontologia 

 Indica, 5 ' a full part containing a large section of the Brachiopoda 

 of the productus limestone of the Salt range, by Dr. Waagen, was 

 published ; also a part on the tertiary Echinoidea of Each and 

 Katkiawar, by Dr. Duncan. Mr. Mallet issued a descriptive catalogue 

 of the systematic series of minerals in the museum, and a guide to 

 the economic mineral products, giving a very instructive account of 

 each class of substance, its use and distribution. 



With the co-operation of Mr. H. P. Blanford, the Meteorological 

 Reporter to the Government of India, some simple seismometric 

 instruments were set up at Silchar, Sibsagar, and Shillong, forming 

 a group for the determination of centres of earth disturbance in 

 Assam. 



During the year two able members of the Department retired. 

 Mr. Wynne, who had left India on medical certificate in 1880, had, 

 after several extensions of sick leave, to be finally invalided in 1883. 

 He had joined the Indian Service in 1862, having already had 

 several years' geological experience in Ireland. In India some 

 choice fields of work fell to him, such as Cutch and the Salt range, 

 excellent illustrated descriptions of which have appeared in the 

 "Memoirs." Mr. Lydekker, the other retiring member, had had a 

 short but a very busy career. He joined the Survey in 1874, and 

 as soon as the collections were moved to the new museum and 

 amalgamated with those of the Asiatic Society of Bengal, he under- 

 took the arrangement and description of the extensive series of 

 tertiary vertebrate fossils, large additions to which were made by 

 Mr. Theobald in the Punjab. Mr. Lydekker's description of the 

 Siwalik fauna in the " Pakeontologia Indica " will form an enduring 

 record of his zeal and ability. 



During the same year two new assistants joined the Survey, 

 Mr. E. J. Jones, A.S.R.M., and Mr. C. S. Middlemiss, B.A. (Cantab). 



The Karnul cave explorations commenced by Mr. Poote, and 

 continued by his son Lieut. H. B. Foote, R.A., proved to be on the 

 whole encouraging, a large number of bones were secured, some of 

 animals that do not now inhabit the region, some human remains 

 and articles of human manufacture, the latter at the considerable
