of merely local interest, publish from time to time papers of more 

 or less value, that it becomes a matter of considerable difficulty for 

 the working naturalist to know what has been done upon any 

 subject that may come before him. From this point of view the 

 ' Tear-Book of Scientific and Learned Societies,' of which the 

 second issue is now before us, is a publication of considerable 

 importance, and we can only hope that it may receive sufficient 

 patronage to justify the publishers in continuing its production. 



This second issue forms an octavo volume of 230 pages, and eon- 

 tains a list of societies, institutions, associations, clubs, and other 

 similar bodies established for the cultivation of science, and including 

 also some which hardly come under that denomination in the ordi- 

 nary sense, being devoted to the study of agriculture and horti- 

 culture, law, literature and history, and medicine. By far the 

 greater part of the bodies referred to, however, fall more or less 

 strictly under the category of scientific societies, and of these we 

 find detailed not only the titles and addresses, with generally the 

 names of the presidents and other officers, but also complete lists of 

 the papers read at their meetings during the year 1884, of the 

 doings in which this second " year-book " is a record. The societies 

 referred to in the volume are classified under fourteen heads, so as 

 to bring together those which are established to perform similar 

 functions, or to deal with the same or allied branches of knowledge, 

 while the reference to any particular body is facilitated by the 

 addition of a copious index arranged alphabetically.

DUBLIN MICROSCOPICAL CLUB. 



April 24, 1884. 



Section of Schorliferous Quartz. — Prof. V. Ball showed a section 

 of schorliferous quartz containing minute cells lined with a mineral 

 dendritically arranged, possibly manganese. 



Teclmitella legumen new to Irish Waters. — Prof. Haddon showed 

 specimens of Teclmitella legumen (A. M. Norman) collected by Mr. 

 Charles Elcock in the Irish Sea, near the Isle of Man ; the first time 

 it has been found in Irish waters. 



Gorynium Beijerinckii, a Fungus causing the '^gumming" of 

 Cherries. — Mr. Greenwood Pirn showed Corynium BeijerincJcii, a 

 fungus said to be the cause of the gumming of cherries and other 

 fruit-trees, other species producing " gum tragacanth " and similar 

 products. The plant consists of a darkish, jointed, rather knotty 

 mycelium, which produces 3-4- septate spores, broadly fusiform and 

 somewhat constricted at the joints.
