Tripos. In 1883, he succeeded the late E. B. Tawney as assistant to 

 Professor Hughes, the Woodwardian Professor, and gave many 

 lectures and demonstrations in Palaeontology. In 1886, he gained 

 the Sedgwick Prize for an essay on " The Jurassic Rocks of the 

 Neighbourhood of Cambridge " — a work which, unfortunately, has 

 not been published. To the Jurassic rocks he had devoted especial 

 attention, having, in the summer of 1884, been sent out by the 

 University of Cambridge, with a grant from the Worts Fund, to 

 study the Jurassic rocks of the Jura. The results of this journey, so 

 far as regards the correlation of the Upper Jurassic Rocks of the 

 Swiss Jura with those of England, were communicated to the 

 Geological Society of London, and published in 1887. Another 

 important paper by Mr. Roberts, on the equivalents of the Corallian 

 beds in Lincolnshire, was published by the same society in 1889. 



In conjunction with Mr. J. E. Marr, in 1885, Mr. Roberts had 

 described the Lower Palaeozoic rocks of the neighbourhood of 

 Haverfordwest, and he had also written some papers on special 

 Palaeontological subjects, describing a species of Conoceras, and some 

 abnormal Cretaceous Echinoids. He died on January 24, after an 

 attack of influenza, and in consequence of failure of the heart. He 

 was buried at Tenby, his old home. 



JAMES AUGUSTUS GRANT. 

 Born April ii, 1827 — Died February ii, 1892. 



BY the death, on February nth, of Col. J. A. Grant, the well- 

 known East African explorer, we seem almost entirely severed 

 from what may be called the Livingstone epoch in the opening out 

 of the Dark Continent. Col. Grant was born at Nairn in 1827, and, 

 after serving with distinction in India, both at the sieges of Multan 

 and during the Mutiny, entered, in i860, that field of x\frican explo- 

 ration with which his name will ever be associated. In that year he 

 joined the expedition led by Speke to explore the Victoria Nyanza, 

 which had then been but recently discovered by the latter in his 

 previous expedition with Burton. The two travellers, starting from 

 Zanzibar, journeyed to the north-west side of the lake, and after 

 sojourning in Uganda with the now celebrated late King Mtesa, had 

 the satisfaction of verifying the prediction of the older explorer that 

 the main source of the Nile would prove to be the northern side of 

 the Victoria Nyanza. It was not, however, to be supposed that a 

 mere preliminary reconnaissance, like that which Speke and Grant 

 were enabled to make, could give us an accurate map of the lake, 

 and it is, therefore, no discredit to them that this task ultimately fell 

 to the lot of Stanley. The prolonged absence of the two explorers 

 led to the dispatch of a rehef expedition, under Sir Samuel Baker, 

 who met them, in February, 1863, at Gondoroko, on the upper waters
