engrossing, he extended his range of geological work from the earlier 

 palaeozoics to the Pre-Cambrian rocks, and to the investigation of glacial 

 deposits. But he was also active in local affairs, especially in questions 

 sanitary and educational, as well as in church work, and in the 

 organization of the Conservative party. In fact he was never idle. 

 His sturdy frame, clear and ruddy complexion, dark hair only grizzling, 

 unflagging energy, and seemingly abundant vitality gave promise of a 

 long life. Of late years, however, he had suffered occasionally from 

 rather severe attacks of rheumatic gout. One recurred in the autumn j 

 it affected the heart, and he passed away on November 18, 1899, 

 leaving a widow and three married daughters. 



He was equally active in scientific organisations, taking part in the 

 excursions of the Geologists' Association, of which he was President 

 from 1883 to 1885, in the meetings of the British Association, and in 

 the Geological Society of which he was Secretary from 1890 to 1893 

 and President from 1896 to 1898, being a member of the Council and 

 Vice-President at the time of his death. By that society he was 

 awarded the Bigsby Medal in 1883, and he was elected a Fellow of the 

 Eoyal Society in 1885. 



Hicks wrote, in addition to some medical notes, about sixty-three 

 geological papers. The most important appeared in the ' Quarterly 

 Journal of the Geological Society,' but he also contributed fre- 

 quently to the ' Geological Magazine,' the ' Proceedings of the Geolo- 

 gists' Association,' the ' Eeport of the British Association,' ' Nature,' 

 and other periodicals. These papers may be grouped under the 

 following heads : (1) The earlier palaeozoic strata of Pembrokeshire. 

 The first, as already stated, to discover fossils in the Lower Cambrian of 

 St. David's, he afterwards proved that the beds beneath the Menevian 

 (which was distinguished from the Lingula Flags by the joint work of 

 himself and Salter), could be sub-divided into an upper or Solva group, 

 characterised, like the Menevian by the presence of the trilobite 

 Paradoxides and a lower or Caerfai group, which no doubt corre- 

 sponds with the Olenellus zone, although that trilobite has not yet been 

 identified with certainty at St. David's. But besides this, Hicks worked 

 out the whole Pembrokeshire section upwards from the Menevian to 

 the Llandeilo, indicating the position of important volcanic discharges 

 and proposing to group the upper part of the Arenig with some of 

 the Llandeilo as the Llanvirn beds. In one paper, published in the 

 * Journal of the Geological Society,' he reviewed the distribution and 

 distinctive characters of the Cambrian and Lower Silurian strata of 

 Europe, pointing out their bearing on the physical geography of those 

 ages. 



(2) The second group of papers, begun in 1877, dealt with the 

 beds underlying a conglomerate which apparently serves as a base to 

 the St. David's Cambrian. Of these he made two divisions, the upper
