lobate, lacinise sinuate-incised, often imbricated, smootli, laxly 

 affixed; medulla pale yellow, thin (C yellow) ; under surface black, 

 towards the margin brown, with black branching radicles; 

 apothecia unknown. Intermingled with, it were specimens of 

 P. physodes, Ach. 



Dr. Stirton also exhibited the Lichen Lecanora Breadalbanensis '^,, 

 new to science, found by him on Ben Lawers ; he also laid on the 

 table a large tuft of the moss Myurium HebridaruTn, which he had 

 received from T. J. Bulkeley, Esq., Procurator Fiscal, Lochmaddy, 

 and referred to the observations on this species which he made 

 at a previous meeting when discussing some of the "Challenger" 

 specimens. 



By Mr. Cameron — A variety of Taxonus hicolor, Kl. ; inter- 

 mediate between the type and T. coxalis, KL, showing that the 

 latter must necessarily be a variety of T. bicolor. He also exhibited 

 a new species of Eriocampa taken by him near Beauly, and which 

 he has named E. testaceipes. It is nearly related to E. cinxia (as 

 shown by the similarity in the structure of the posterior wings) 

 but is at once distinguished by having the feet nearly all of a 

 testaceous colour.

 the first links of the vast chain of law which unites all nature in 

 one. The schoolman, with his dream of intuitive knowledge to be 

 attained by the mind purified by severe privation, has vanished, 

 and in his place we have got the healthy, vigorous naturalist, and
