the map-colourists in a manner that remains unexcelled, 

 and it is to be regretted that zeal for uniformity has intro- 

 duced the cruder tints of British maps in later years. 

 Irish geology has from time to time been the victim of 

 obsessions. Just as Jukes in his last years sought to over- 

 throw the Devonian system, and succeeded in impressing 

 his views on G. H. Kinahan, so Hull felt drawn towards 

 marking out, on very shadowy indications, a line between 

 a Dingle Series and an Old Red Sandstone throughout the 

 south. Undated " revisions " were thus made in a large 

 number of sheets, the bibliography and collation of 

 which will prove a complete puzzle to librarians. For- 

 tunately, these changes are purely of stratigraphical 

 interest, and in no way affect the economic and practical 

 value of the sheets concerned. It is well, however, that 

 the southern maps as originally issued should be preserved 

 for comparison with those of later date. 



Hull took a keen interest in Glacial problems. In 

 common with many geologists trained in England and 

 profoundly influenced by Lyell, he regarded the deposits 

 of drift as aqueous rather than as directly due to the melting 

 of stagnant continental ice. But he rightly urged that 

 Ireland revealed evidence of an interglacial epoch, and his 

 work on the correlation of the sands and g-ravels of the 

 eastern coast tends to be strengthened and confirmed by 

 later observations. 



In his " Reminiscences," Hull gives an agreeable picture 

 of life in Dublin when Sir Robert Kane, Dr. Johnstone 

 Stoney, and Sir Robert Ball — to name no others — were 

 prominent in the scientific life of the metropolis. Work 

 has since tended to be more specialised and perhaps more 

 truly " strenuous " ; but it is pleasant to think that many 

 of the institutions to which he refers stiU serve as grounds 

 of meeting, and that the Scientific Club still brings together 

 in social converse workers in very diverse fields. 



Hull married in 1857 the daughter of Dr. C. T. Cooke 

 of Cheltenham, and had four daughters and two sons, most 

 of whom survive him.
