Ordinary. 

 Maharaja Isvariprasad Singh, G. 0. S. I. of Benares. 

 Dr. D. Waldie. 



Honorary. 



Professor "William Wright, Cambridge. 



The President said : — I very much regret to have to announce 

 the death since our last meeting of Dr. D. Waldie, one of our oldest 

 members of Council. Dr. Waldie joined the Society in 1865 and had 

 served on the Council since 1879, having been Vice-President in the 

 years 1884 and 1885. He was a most regular attendant at our meetings, 

 and was always ready to further the work of the Society in auditing 

 accounts and giving his services on the various Committees. 



He published several papers in the Journal and Proceedings, most 

 of which were connected with the Water-supply of Calcutta and the effec- 

 tive filtration of the Hooghly water during the rainy season, which has 

 always been a difficulty. 



Before Dr. Waldie came to India some forty years ago, he had been 

 connected with Sir James Simpson, who was the first to apply sulphuric 

 ether as an anaesthetic, and appears to have suggested to him the use 

 of chloroform instead of ether, though our late friend and associate 

 does not seem to have received full credit for his share in one of the 

 most important discoveries of the age. 



A man of retiring and unassuming ways, we here had few opportu- 

 nities of knowing the full extent of his scientific work, but as an ana- 

 lytical chemist and chemical manufacturer he undoubtedly did much to 

 promote chemical science in this country. I believe he also did good 

 service in connection with the establishment of Libraries and Institutes 

 in the neighbourhood of his works at Cossipore and Dakhinsur. We 

 shall miss his kindly presence here, and he will be regretted by many 

 who knew his worth. 



Dr. W. King exhibited some specimens of interesting minerals. 



The Secretary gave a summary of the observations received from 

 different sources regarding the explosive sounds known as the " Barisal 

 Guns " and showed how the theory, suggested by Mr. Manson, that they 

 are echoes, explains many peculiarities observed in connection with these 

 sounds. 



The following papers were read — 



1. On certain Lycsenidse from Dower Tenasserim. — By Wm. Doherty 

 Esq., Cincinnati, TI. 8. A. Communicated by the Superintendent of the 



Indian Museum.
