REPORT OF COUNCIL. ^ / 



the Thallus of Evernia prunastri (Ach.),' by Admiral T. Jones, F.L.S.; 

 ' Notes on a supposed New Variety of Orchis latifolia (Linn.), and on 

 Orchis incamata, var. externa (Beichenbach),' by David Moore, Ph. D., 

 F.L.S. 



" The foregoing papers will appear in full in the forthcoming ' Part' 

 of the t Proceedings.' It will form < Part II.' of Vol. IV. It is now at 

 press, and will shortly be ready for distribution. 



" The system of exchange of publications with English and foreign 

 kindred Societies, commenced last year, has been vigorously carried on. 

 Part I. of Vol. II. (that for the Session 1862-3) has been forwarded by 

 post to various English, Scotch, and American Societies, and through 

 the agency of Messrs. "Williams and Norgate, of London, to many So- 

 cieties on the Continent of Europe. From a considerable number of 

 these their publications for last year have been received, whilst several 

 have most kindly sent the whole of their publications from the com- 

 mencement. To all of these Societies who have hitherto so generously 

 acceded to the proposal to open such an interchange, your Council 

 would beg to offer, on behalf of this Society, its hearty acknowledg- 

 ments and thanks, for this, on the part of the former, more than reci- 

 procity. Promises of an opening of a mutual interchange have been 

 received from a few Societies whose contributions have not reached 

 this Society, but which, doubtless, will shortly be realized, as it is pro- 

 bable that even now several packets may be on their way hither. 

 From others no response has yet arrived. To such another application 

 will not fail to be made when forwarding the forthcoming Part of our 

 1 Pi-oceedings,' which, when ready, will be despatched to all the So- 

 cieties to whom the previous Part was sent. A complete list of all the 

 Societies to which Part I. of Vol. IV. has been sent will be found in 

 the Appendix thereto ; and likewise in the Appendix to it and to Part 

 II. will be found a list of the various publications received from other 

 Societies in exchange, as well as from private individuals. All these 

 abound with memoirs of much scientific importance and interest ; and, 

 if even but a few of our workers here in any field of Natural Science 

 should find matter of interest in any of them, the trouble of conducting 

 these exchanges and the slight incidental expense will have been use- 

 fully and beneficially expended. 



" It is to be regretted that better means of placing these valuable 

 contributions in an accessible manner, so as to enable the members to 

 see what we have and what we have not, is not at disposal. However, 

 at any time an application by any of the members for any particular 

 Journal in the possession of the Society, addressed to Mr. Archer, will 

 be forthwith gladly and promptly attended to. 



" Your Council cannot refrain, moreover, from drawing attention 

 to the fact, and, whilst inviting original contributions, would respect- 

 fully urge upon those observers in Dublin and in all parts of Ireland 

 who have observations in any department of Natural History to com- 

 municate, that a Journal which circulates amongst so many kindred scien-
