The President then rose, and said that he was sure but one opinion 

 was entertained with regard to the importance of the researches of Ad- 

 miral Jones among such an interesting and beautiful tribe of plants as 

 the Lichens, and especial thanks were due for the four fasciculi, rendered 

 more valuable by the volumes accompanying them, containing such 

 copious notes with regard to the species. Since the days of the late 

 Dr. Taylor, of Kenmare, who carried on his valuable investigations, in 

 continuation of those of Mr. John Templeton, of Cranmore, near Belfast, — 

 whose universal attainments in the natural history of bis country have 

 been the admiration of all enthusiastic naturalists, — few have persisted in 

 forming any complete collection of that beautiful Order of cellular flower- 

 less plants. Whether we view them with regard to the interest of 

 geographical distribution, to the effects of geological formation, or to 

 their value in the arts, we must consider them as altogether possessing 

 peculiarities and utilities, the importance of which as relates to those of 

 this country has not been sufficiently recognised. Lichens, like the 

 fungi, are affected in their growth by climatal influence, as well as by 

 characteristics of geological structure, and by peculiar trees and plants 

 on which they perennially exist. Thus the limestone rocks, such as 

 those of JJurren and of Arran, may present those beautiful species 

 Verrucaria Ilermanni and glaucina, associated with V. plumlea and 

 Squamaria crassa. Collemas are beautiful; and one found on Brandon 

 associated with C. spongiosa had all the characters of C. subtile, the 

 most minute of lichens. Lichina confinis forms a connecting link, with 

 Stigonema, to the algae, and is of interest, as is also Byssus iolithus — 

 St. Winifrid's Blood. The singular distribution of some is remarkable, 

 as Sticta macrophylla, Kerry being its only known European locality, 

 and distributed in the Mauritius, and on the Peruvian-bark trees of South 

 America. The fungi are equally singular, as represented by Cyttara 

 Darwinni, found on beech trees in Terra del Puego, and on similar trees 

 in Chili and New Zealand. The importance of the Lichens is their uses 

 in the arts. The Lecanora parella is abundant in Kerry, as well as the 

 Gyrophora pustulata. The former dyes every tinge of crimson and purple, 

 and is the famous pcrelle of the Limague d' Auvergne, near Vichy. The 

 latter dyes a rich crimson. To the fly-tier and angler, Lecanora tartarea 

 and Parmelia saxatilis form valuable dyes. Roccetta fuciformis, a species 

 identical with the famous Archill (Orseille des Canaries), has been met 

 in the West Blasquet Island, with, in abundance of fine growth, Borrera
