production of falls of snow in the higher northern latitudes, and, 

 therefore, an increased snow-fall in one portion of these latitudes 

 must be compensated by diminished snow-fall in another portion. 



I have omitted to notice the effects which might be produced when 

 the snow-caps thus formed were set in motion. Moving masses of 

 ice or snow might considerably alter the general phenomena of 

 glaciation. If we take the most southerly portion of our hemisphere 

 in which permanent glaciation is possible, the snow-cap would form 

 most readily if the irruption of northern ice commenced about the 

 same period when the conditions for local glaciation were becoming 

 favourable. These latter conditions would, I apprehend, be most 

 favourable when the earth was in aphelion at midsummer ; but the 

 Polar Pack would not attain its full dimensions until some time after 

 the mid-winter aphelion, and in its slow southward motion it might 

 not begin to overrun the northern portion of the Temperate Zone 

 until a still later period. The invasion of Polar ice might nearly 

 coincide with the commencement of the local glaciation produced by 

 very different causes, and a Glacial period would result.

EDWARD TOWNLEY HARDMAN, F.C.S., F.R.GS.I., ETC. 



Born 6th April, 1845 ; Died 30th April, 1887. 



(^ EOLOGICAL science has suffered a serious loss in the early 

 T death, from typhoid fever, of Mr. Hardman, of the Irish 

 branch of the Geological Survey of the United Kingdom. 



Descended from an old and respected Drogheda family, Mr. 

 Hardman received his early education at that town. Having by his 

 ability won a Government Exhibition and entered the Eoyal College 

 of Science, Dublin, in 1867, he obtained a diploma in mining, 

 etc., as well as numerous prizes, and in 1870, he was appointed to 

 the staif of the Geological Survey of Ireland. In 1871 he was 

 elected a Fellow of the Geological Society of Ireland, and in 1874 of 

 the Chemical Society of London. 



He examined, and prepared a Memoir upon, the Geology of the 

 Coal-fields of Kilkenny and Tyrone, and prepared a list of papers 

 on the Geology of the North of Ireland. Mr. Hardman was also an 

 active and earnest antiquary, and communicated several papers to 

 the l\oyal Irish Academy. 



In 1883 he was selected by the Colonial Office to examine and 

 report upon the geology and mineral resources of the Kimberley 

 district of the colony of West Australia. Here he was attached to 

 a local surveying expedition, under the direction of the Hon. J. 

 Forrest, C.M.G., Crown Surveyor General to the Colony, and set 

 out for the North-East Territory. Having a camera, he was enabled 

 to photograph numerous points of interest, and also to make sketches 

 of characteristic geological sections. The most important practical
