THIRSK NATUEAL HISTORY SOCIETY. 

 Botanical Exchange Club. 



The monthly meeting of the Thirsk Natural History Society 

 was held on the evening of Monday, the 2nd of May. Mr. J. A. 

 Knights, of Norwich, was elected a member of the Exchange 

 Club. Mr J. G. Baker communicated the following notice : — 



"Delphinium Ajacis. — The Rev. W. R. Crotch writes: — 'It may 

 perhaps interest you to be told that the specimens of Delphinium 

 in my herbarium, one sent to me by Professor Henslow, from 

 Cambridgeshire, one gathered by me in Davenport Wood, near 

 Bridgnorth, in Shropshire, and one near Greenwich, were all 

 labelled by me D. Ajacis at the suggestion of a German botanical 

 friend. Two of them have the pubescent carpels, and the third has 

 the habit of Ajacis, BXidi not that of Consolida, as given by Koch.-'" 



He also read a paper from Mr. J. H. Davies, entitled, ' Notes 

 on the Muscology of Colin Glen, county Antrim.' 



'^ On the 25th of last month, in company with two of my rela- 

 tives from Liverpool, my friend John S. Ward, and a number of the 

 boys from the Friends' School at Lisburn, I made an incursion, 

 for the first time, into Colin Glen, chiefly known to bryologists 

 as a reputed locality for Neckera pennata ; and I thought that, 

 as serving to illustrate the muscology of the more elevated parts 

 of this district, a short notice of our excursion might not be alto- 

 gether unacceptable to our Members. 



*'0f the range of mountains, which run nearly east and 

 west, including Cave Hill, Devis, Colin, Black Mountain, and 

 Aughrim, extending from Belfast to within a short distance of 

 Glenarsy, Colin is situated about midway, and is distant some- 

 what upwards of three Irish miles from Lisburn. 



'^We started out shortly after breakfast, mustering ten or 

 twelve vascula, and provided with sundry ingenious contrivances 

 for boiling cocoa and eggs a la Gipsy. Taking the road towards 

 Derriaghy, we stopped only for a very short time cursorily to 

 examine a cutting in the New Red Sandstone, which on a former 

 occasion had yielded us Tortula vinealis and T. aloides, the 

 latter in considerable plenty, and with fully matured capsules. 

 So far as I have had opportunity of observing, this species, in 

 Yorkshire and in other localities that I have visited, is almost, if 

 not entirely, peculiar to limestone districts, so that I was not a
