i66 The Irish Naturalist. [July- 



Mr. H. Hanna exhibited sections and specimens of a new species of 

 Truffle from Cy'^xws—Tcrfezia aphrodites. In Terfezia we have a type of 

 Truffle in which the large masses of fertile hyphae are separated by 

 white bands of sterile hyphae which come off from the outer hardened 

 layer of hyphae or peridium. It is described by Chatin, in the Bidletm 

 dc la Societi Botanique de France, 1897, p. 290. 



Mr. Joseph Wei,i,and showed a new photo-micrographic apparatus, 

 the property of Professor Cunningham, consisting of a long board, having 

 attached above a light framework covered in with curtains and carrying a 

 vertical sliding stage for holding plate-holders It is used in conjunction 

 with a projection lantern with microscopic attachments, a partition fitted 

 with shutters being interposed between the lantern and the stage.

May 21. — Spite of the stormy weather nearly forty members of this Club 

 and their friends took train to Howth to collect objects of natural 

 history interest on Ireland's Eye. Boatmen and coastguard look-out 

 agreed it was useless to try to make the passage. The party turned, by 

 permission, into the Howth demesne, walked through the beautiful 

 rhododendron dell, saw the peculiar Adder's Tongue fern in quantity, 

 and paid a visit to the boggy patch where the Sundew, the Butterwort, 

 and other interesting plants were seen growing. 



June 18. — Members and their friends travelled from Harcourt-street 

 Station by the 10 a.m. train, reaching Rathdrum at 11.30. Here cars were 

 taken to Drumgoff. After lunch the valley of Glenmalure and the 

 mountain slopes, west of Drumgoff, were explored. Saxifraga stellaris, 

 Drosera rotimdifolia^ Pingiiicula vulgaris, P. lusitanica, several species of 

 Lastrea and other ferns, &:c., were obtained. Few birds were seen, and 

 the day was not favourable to entomological collection. On the whole 

 the ground proved disappointing, though the excursion was much 

 enjoyed by all, thanks to the fine mountain scenery.
