W. L<amplugh, has given us an admirable account of the 

 drift-deposits and glacial features around Dublin (pp. 183- 

 199). The Balrothery and Drimnagh esker, as described by 

 Mr. M'Henry (p. 195), has been found to rest at one point on 

 a water-worn surface of limestone, which is good evidence of 

 its formation in a true sub-glacial tunnel " at ground level" 

 (p. 187). Mr. Kilroe, who is largely quoted, regards the 

 shelly gravels as derived from the washing of the boulder- 

 clay during times of flood, and the boulder-clay as originally 

 pushed up over the land, with marine shells in it, from the 

 floor of the Irish Sea (p. 193). Mr. Wright describes a glacial 

 gap connecting the valleys of Killakee and Glenasmole. We 

 may be pardoned if we perceive, throughout these interesting 

 pages, the mind of the accomplished District-Geologist, as 

 gentle and yet as powerful in its moulding action as were the 

 glaciers themselves, when they smoothed and harmonised the 

 old-time asperities of the land. 



THK CRUMI.IN METEORITE. 



Mr. Iv. Fletcher, F.R.S , of the British Museum (Natural 

 History), describes in Nattire^ vol. Ixvi., Oct., 9, 1902, p. 577, 

 the fine meteoric stone which he has secured for the lyOndon 

 collections. As is now well known from the paragraph in the 

 Northern Whig for 17th Sept., the meteorite in this instance 

 was actually seen to fall on 13th September, 1902, and was 

 accompanied by considerable noise. It weighs about 9J lbs., 

 and is one of the sporadosiderites of Daubree, i.e. a rock formed 

 of basic silicates with difi'used particles of nickel-iron. The 

 glaze on the surface, produced by the heat of friction with our 

 atmosphere, is complete ; but a portion of the stone must have 

 been broken off in the air, the new surface thus formed being 

 covered with a thinner glaze than the remainder of the stone. 

 Mr. Fletcher presumes, from the limited area over which the 

 stones of any one fall are distributed, that the missing portion 

 fell into I^ougli Neagh. 



The meteorite at present stands in a central position in the 

 great hall of the National History Museum at SouthKensingtou, 

 and a coloured reproduction in plaster has been courteously 

 presented by the Trustees 'of the British Museum to the
