strati graphical position of the divisions of this system and their 

 relations to older and younger formations. He contended that the 

 conditions under which the Old Red Sandstone was accumulated 

 ma}'' not have been of the character of inland lakes having no con- 

 nexion with the sea, and that these conditions may have been in 

 operation before the close of Silurian time and after the beginning 

 of the Carboniferous Period. He held that the 3^oungest Silurian 

 rocks, a portion of the Old Red Sandstone, and some of the oldest 

 Carboniferous strata may have been deposited contemporaneously. 



This volume formed his only contribution to geological literature. 

 His highly speculative views did not meet with a cordial reception, 

 due largel}^ to his lack of appreciation of the value of palseonto- 

 logical evidence and of the importance of the accurate determina- 

 tion of the geological structure of the areas with which he dealt. 

 He was full of enthusiasm for geological speculation and fond of 

 discussing his peculiar views, always in a genial tone. 



He was elected a Fellow of this Society in 1901, and died on 

 December 5th, 1919. [J. H.] 



Aethur Johx Charles Molt>'Eux, a pioneer in Rhodesian 

 geolog}", possessed an inherited bent for the science, his father, 

 William Molyneux, a former Fellow of our Society, having done 

 much good work in his time, first at home, and afterwards in South 

 Africa. The son, born about 55 years ago, was trained as a mining 

 geologist, and Avas one of the band of adventurous spirits who 

 entered Matabeleland as soon as it was opened for prospecting in 

 the early nineties. He remained a devoted Rhodesian for the rest of 

 his life, making Bulawaj^o his home or headquarters, and, by various 

 exploring trips, both north and south of the Zambesi, he acquired 

 a Avide and often exclusive knowledge of the general structure of 

 little-knoAvn regions. In 1903 he contributed to our Journal an 

 excellent paper on ' The Sedimentary Deposits of Southern Rho- 

 desia,' and in 1905, in a communication to the Royal Geographical 

 Society, he discussed ' The Physical History of the Victoria Falls,' 

 based on his personal investigation — being the iirst to give a 

 scientific account of the wonderful spectacle, and to explain its 

 origin. In 1909 he brought before our own Society a paper ' On 

 the Karroo System in Northern Rhodesia,' which described for the 

 first time a region hitherto unexplored geologically. Other papers 

 were published by him in South African scientific journals, 

 including several in the Proceedings of the Rhodesia Scientific
