Docidium Mrsutum, Bailey, occurring in Scotland, exliibited. — 

 Mr. Archer showed examples of Docidium hh-sufnin, Bailey, takeu 

 on the Deeside, in Scotland ; it was very scanty indeed in the 

 gathering, but Mr. Eoy informed Mr. Archer that he had before 

 encountered it. It seems to be scarcely happily named, as the 

 roughnesses on the superficies partake, so to say, more of the cha- 

 racter of elongate papillae than of "hairs;" but Bailey speaks 

 of it as " strongly hirsute," possibly in allusion to the coarseness 

 of these " hairs " — a point perhaps rendering the identification 

 of the form the more certain, but still his figure, in that case, 

 shows the roughnesses as rather fine. It is not a very pretty 

 form ; the wall appears thick and somewhat opaque, and the green 

 "contents not of a lively tint. In these countries, at least, it must 

 be surely a very rare species. 



Section from an Encliondroma of Tibia, exhibited. — Mr. B. Wills 

 Eichardson exhibited two stained sections, one red, the other blue, 

 taken with the freezing microtome, from an enchondroma that 

 sprang from the head of the tibia of a young man. The tumour 

 attained to a large size in a few months and amputation above 

 the knee had to be performed. The case had a malignant history, 

 death having occurred a year after the operation. The cells and 

 their nuclei were large and there were one or two ossific centres 

 in each section. 



JExhihition of Octaviania asterosperona, Vitt. — Mr. Pim exhi- 

 bited Octai'iania asterosperma, Vitt. This, the first hypog^ous 

 fungus that Mr. Pim had met with, occurred in his garden at 

 Monkstown, on a piece of old carpet that had been dug-in with 

 manure. It appears to be but very sparingly distributed both in 

 England and on the Continent, and is now, it is believed, recorded 

 for the first time in Ireland. 



Section of Dolerite, containing the neio mineral Hullite, Hard- 

 man, exhibited. — Professor Hull, F.E.S., exhibited a thin section 

 of the olivine dolerite of Cavmoney Hill, near Belfast, containing 

 tlie new mineral called " Hullite," by the discoverer, Mr. E. T. 

 Hardman, who has given a description of it at the recent meet- 

 ing of the British Association in Dublin (Section C). The mineral
