choice slides, prepared with his usual skill. Mr. Joseph Wright, 

 F.G.S., exhibited two interesting arenaceous forms oi Foramini- 

 fera {Astrorhiza limicola and Psammatodendron arhorescens) 

 recently dredged by Mi. David Robertson, F.L.S., &c., of Glas- 

 gow, off Cumbrae, Firth of Clyde. The latter is a very re- 

 markable branching form, more like a plant than a foramini- 

 fer, and only recently found living in British waters. A frag- 

 ment of the same thing was also lately dredged off Portstewart. 

 Rev. John Bristow kindly lent an exceedingly choice and valu- 

 able collection of British Lepidoptera, numbering many hun- 

 dred specimens, which was greatly admired. Mr. Isaac Waugh 

 also showed an interesting series of lepidoptera, collected by 

 him in the vicinity of Belfast. Mr. Robert Walsh exhibited 

 some artistic mounts of insects and dried plants, also many liv- 

 ing insects in a fresh-water aquarium. Mr. W. H. Phillips had 

 some very remarkable insectivorous plants, also some growing 

 ferns, one of which was strikingly Variegated. Mrs. John JafFe 

 exhibited some beautifully mounted Alpine plants, also some 

 tubes containing young salmon in various stages of growth. 

 Canon Macllwaine sent in several good specimens of minerals 

 and fossils. Considerable discussion was excited by an ele- 

 phant's tooth said to have been found in a bog near Strabane, 

 but regarding this more information is desirable. Professor 

 Everett greatly added to the interest of the evening by exhibit- 

 ing and working Donkin's homonograph, a beautiful machine 

 which describes varied and intricate designs on paper. The 

 Rev. John Andrew contributed an album of figures traced by a 

 somewhat similar machine, the pendulograph. The exquisite 

 beauty and delicacy of these figures were much admired during 

 the evening. Electricity, steam's new rival, was represented 

 by a working model of an electro-magnetic engine, the pro- 

 perty of Mr. John Stears, of Holy wood, who obligingly ex- 

 plained and superintended its working during the entire evening. 

 This proved to be one of the greatest attractions of the meeting. 

 The pictures so freely lent by members and their friends added 

 very much to the attractive character of the rooms, [n a pro-
