50 The Irish Naturalist, May, 



Enniskillen ones. A really delightful memento of this tour 

 is Martel's little book entitled " Irlande et cavernes 

 anglaises," published in Paris in 1897. In spite of its title 

 it deals largely with Irish caves. 



After having finished his studies in Dublin, Jameson 

 spent a year at the Royal College of Science in London 

 with Prof. Plowes, and then proceeded to Heidelberg. As a 

 pupil of Prof. Biitschli he had the advantage of being taught 

 hy one of the foremost microscopists in Europe. After 

 taking the degree of Ph.D. in Heidelberg, he returned to 

 Ireland, and shortly afterwards accompanied Prof. Herd- 

 man, of Liverpool, to Ceylon in order to study the pearl- 

 oyster fisheries. Dr. Jameson's papers on the structure 

 and origin of pearls were favourably received, and he showed 

 in them considerable originality, having established the 

 parasitic theory of pearl formation. Unfortunately failing 

 health prevented his remaining in England. Owing to 

 threatened consumption he w^as obliged to winter abroad. 

 He selected South Africa, and obtained employment under 

 the educational authorities of the Transvaal. Having 

 somewhat regained his strength he returned to England a 

 few years before the war broke out and entered the Board of 

 Education. All this time he longed to be back at some 

 occupation that was more congenial to his tastes, and 

 when he was offered an inspectorship for the south-east coast 

 by the Ministry of Agriculture and Fisheries, he accepted 

 it with delight. But the winter climate played havoc with 

 his health, and he found himself less and less able for any 

 kind of physical exertion. His last appointment was that 

 of adviser on Inshore Fisheries to the Development Com- 

 mission, where his advice and knowledge were greatly 

 appreciated. He was of a gentle and lovable disposition, 

 combmed with resoluteness of character and determination 

 which enabled him to overcome the many difficulties and 

 trials in life which he was destined to face. He leaves a 

 widow and two daughters.
