Continent. Nearlv every standard work in these departments of 

 science, published during that period, contains acknowledgment of 

 assistance received from him. The most distinsjuished biologists 

 have borne testimony to the success of his researches and the value 

 of his contributions to science, and among the names of such may 

 be mentioned Professor Koelliker, Dr. Gwyn Jeffreys, Professor 

 G. S. Brady, Mr. H. B. Brady, Rev. Canon A. M. Norman, Dr. 

 Anton Dohrn, Professor Michael Sars, and Dr. John Murray. At 

 least one genus, and more than a dozen species, have been named 

 in his honour, while the species described from specimens discovered 

 by him have been very numerous. 



He submitted many papers to the societies with which he was 

 connected, as well as to various scientific journals. Of these, the 

 largest number was communicated to our own Society, but others, 

 contributed wholly or partly by him, appear in the Transactions 

 of the Geological Society of Glasgoiv, Proceedings of the Philo- 

 sophical Society of Glasgow, Transactions of the Geological Society 

 of London, Quarterly Journal of the Geological Society, Reports 

 of the British Association, Quarterly Journal of Microscojncal 

 Science, Annals and Magazine of Natural History, &c. 



Having been admitted a member of the Natural History Society 

 of Glasgow in 1852, soon after its formation, he afterwards held 

 office for some time as a Member of Council, and was several times 

 appointed a Yice-President. In September, 1887, he was unani- 

 mously elected President of the Society for a full term of three 

 years. Although, for a long period, he was unable to be present 

 at any of the meetings, his interest in the Society's welfare 

 remained undiminished. This was fully shown by the specimens 

 and communications which he continued to submit'to the meetings, 

 and which in number far exceeded those contributed by any 

 other member. 



In 1859 he became a member of the Geological Society 

 of Glasgow. The same year he also joined the Philosophical 

 Societv of Glasccow, of which he continued a member for about 

 18 years. 



In 1865 he w^as elected a member of the Hoyal Imperial 

 Zoologico-Botanical Society of Vienna, and received its diploma. 

 In 1876 he was elected a Fellow of the Linnean Society of Lon- 

 don, and in 1877 a Fellow of the Geological Society of London,
