II. " On the Fructification of Grijffithnia corallina, with a Notice of other 

 AlgcB found in Shetland not mentioned in Edmondston's ' Flora.' " By C. W. 

 Peach, A.L.S. The author, in examining specimens of Qriffithsia corallina, 

 obtained at the Westroe Outskerries by Miss Jeflreys, observed a circular 

 opening at the lower part of the joints immediately above the whorls of tetra- 

 spores. The edge of the opening was quite smooth, not in the least ragged, as 

 if ruptured. This he found constant over all the whorls of tetraspores he exa- 

 mined. He noticed that the granular matter in the joints escaped through tiiese 

 openings, and that while the tetraspores retained their brilliant colour, the 

 joints became literally colourless. He also found favella on some of the speci- 

 mens, but not both kinds on the same frond. On the lower part of the main 

 stems of some specimens were lateral pointed branches of considerable length, and 

 not jointed; the centres were filled with a dark pigment, which continued 

 into the main stem ; they were placed one on each joint altei'uately. He stated 

 that although he had always kept a good look-out for AlgcB when drrdging in 

 deep water, only three species were got, viz. Desmaresiia viridis, a PoTysiphonia, 

 and a Nitophyllum ; these were found in the inner Haaf at a depth of forty 

 fathoms. He took them from the contents of the dredge, and they were fresh 

 and brilliant in colour, not attaclied to anything. He concluded by giving a 

 list of fourteen species which he had collected, nine of them being additions to 

 Edmondston's ' Flora,' and three from new localities. The paper was illustrated 

 by drawings and specimens. III. " On Two new British Hepaticce." By Dr. 

 Carrington.* IV. " On the Botany of Mamsoul, a High Mountain in Glen 

 Affaric, Inverness-shire." By Dr. Buchanan White. The author gave a 

 general description of Mamsoul and the surrounding district, and noticed the 

 principal plants met with. On Mamsoul he gatliered Lvzula arcuata (new to 

 Inverness-shire) at an altitude of 3000 feet, and not very far below the summit, 

 where also occurred Cerastium trigynum, Cladonia vermicularis and Salorina 

 crocea. He observed Arciostapliylos alpiiia, Cornus Suecica, and Betulanana 

 in many places. Tofieldia palustris on the hills on the south side of Strath- 

 glass ; Nuphar pumila in Glen Cannich ; Subularia aquatica and Isoetes 

 lacustris, very dwarfed, in a stony lake at an elevation of about 2000 feet on 

 Ben Hearag, and of a larger size in pools beside the river Beauty. Plantago 

 serpentina was abundant along the roadsides throughout Glen Affaric, and on 

 the banks of the Beauty, in many places, a large, dark blue-flowered Lupin was 

 thoroughly naturalized. Y. " On some recent Additions made to the Flora of 

 Canada." By Mr. John Sadler. Mr. Sadler enumerated the flowering plants, 

 ferns, and mosses which had been recorded as added to the Flora of Canada 

 during the last two years by Mr. Macoun, Mr. D. A. Watt, and others. He 

 particularly noticed those species belonging to the British flora, including 

 Cystopteris montana, Lastrea Filix-mas, Lobelia Dortmanna, Liltorella la- 

 custris, eight species of Polamogeton, and about twenty species of mosses. 

 Cystopteris montana was found by Mr. Macoun in July, 1869, on one of the 

 northern bays of Lake Superior, growing abundantly in some of the low woods. 

 Mr. Sadler exhibited specimens of tliis rare Fern from Glen Lyon in Perthshire,
