This is the commonest species oi Nitella in the British Isles, and is also 

 common nearly throughout Europe. It is recorded from Asia, N. Africa, 

 and North and vSouth America 



[N. capiiata, Ag., which occurs in the fenland of Cambridgeshire^ and 

 N. syncarpa, Chev., which is common in the West of France, should be 

 looked for in Ireland. Both resemble slender states of N, opaca, but have 

 a gelatinous covering to the fruits ; and N. syncarpa is distinguished from 

 A', opaca and N. capitata by its simple fruit-bearing branchlets.] 



THE GEOI.OGIST AT THE EUNCHEON TABLE- 



BY PROFESSOR GRENVILLK A. J. COLE, M.R.I.A., F.G.S. 



The Refreshment-Rooms organised by the Misses Gardiner, 

 in a house that actually stands upon the demesne of Trinity 

 College, Dublin, have long been recognised as a daily meeting- 

 ground for the members of the staffs of adjacent institutions. 

 In man}^ waj^s these rooms have played the part of the old 

 London coffee-houses, not to say of the ever-famous ** Mer- 

 maid " ; and the manuscripts and^proof-sheets of public and 

 scientific journals, including those of the Irish Naturalist, have 

 often derived an additional sparkle from the conversation 

 carried on around their tables. The opportunity afforded by 

 the reconstruction of the premises has been seized on by 

 several of their confirmed habitues, and a New Year's gift ot 

 seven ornamental tables has been the result. 



Naturally, the polished tops have been made of Irish marbles 

 Under the care of Mr. E- S. Glanville, of Lower Erne-street, 

 Dublin. A scientific committee of selection visited the works.
