I02 The Irish Naturalist. April, 



the present da}^ climatic conditions were in general far severer 

 than now. The resnlt could, therefore, onl}^ give a maximum 

 limit for the time since the close of the Glacial Period, but 

 would still be in some degree a test of the astronomical 

 theor3^ The present state of the evidence as to Glendoo, 

 however, would hardly justify such a troublesome piece 

 of research, but there must be in Ireland other cases of a 

 similar nature, in which the evidence is more definite, and it 

 may be possible at some future time to make sitch measure- 

 ments in other places.

NOTES. 



BOTANY. 



Vegetable Bricks. 



Travelling in the extreme west of Ma3'o, one may see cabins, the walls 

 of which are mainly turf sods ; but these cabins are usually partly 

 excavated under ground in some bank. One hardly expects, however, 

 to find peat-bricks (if I may so call them), used in a large town like 

 Belfast. Yet there were jerry-builders in the "good old times," too, for 

 parts of a wall were lately found built with peat, plastered over, in old 

 business premises in High-street, one of the main streets in the city.

ZOOLOGY. 



New Irish Copepod Crustaceans. 



In the Natural History Transactiotis of Northuniherland^ Durham^ and Ne^v- 

 castle-on-Tyne,\o\. xiv., 1902, some lists of the littoral Entomostraca of 

 the east coast of Ireland are given by Prof. G. T. Brady. These specimens 

 were collected by him in the autumn of 1900, during a short visit to Ire- 

 land, but he also refers to some two net gatherings made on the west 

 coast in previous years. 



Among the most noteworthy features in Dr. Brady's paper are the 

 descriptions with figures of two new Irish species. One {Ameira amphibia') 

 was taken on a mussel-bed between tide marks at Newcastle, Co Down, 

 and another {Laophonie subsalsa) in brackish pools near Dundrum. Co. 

 Down, and also on the west coast of Donegal. Another addition to the 

 Irish fauna \s, Harpactiis gracilis, Claus, which was taken in Roundstone 

 Pay in 1871, but had not previously been recorded.
