Mr. Boyd reported the occurrence of Badhamia rapsulifera, 

 Bull., at Seamill, West Kilbride. The fungus was recently 

 found by him on decaying wood, and forwarded to Dr. M. C. 

 Cooke, by whom it was identified. 



Mr. William Goodwin exhibited a branch of Arbutus Unedo, 

 L., grown in the open air at Innellan, and bearing abundance 

 of flowers and fruit. 



Mr. A. Somerville, B.Sc, F.L.S., showed some beautiful 

 botanical specimens, collected and preserved by a young lady 

 who had obtained the first prize in an herbarium competition. 

 These were remarkable for the perfect manner in which even 

 the most fugacious tints had been preserved. Mr. Somerville 

 stated that the plants had been enclosed in sheets of drying- 

 paper, and a number of these sheets placed between two smooth 

 boards, which were then tightly strapped together and allowed 

 to remain overnight as near a hot fire as possible without 

 burning. In this way the moisture was rapidly dissipated 

 before the colours of the leaves and flowers had in any way 

 been affected by the drying process. 



Mr. John Trotter exhibited some improved microscopic 

 apparatus, including a method of illumination by electricity 

 by means of a very small lamp of special construction placed 

 close to the stage, thus obviating the inconvenience of a large 

 battery and the use of condensers. By this method a very 

 small battery would be found to afford ample illumination even 

 for the highest powers. Very oblique light could readily be 

 obtained for resolving diatoms or opaque objects, or for dark 

 ground illumination, without any of the expensive sub-stage 

 appliances required with the ordinary lamp-light. The small 

 electric lamp could be fitted to any stand without interfering 

 with the use of the ordinary lamp, when its employment might 

 be desired. 



A microscopic demonstration was given by Mr. Trotter at 

 the close of the meeting. 



Mr. James J. F. X. King read a paper entitled "Notes on a 

 Small Collection of Neuroptera from the Island of Coll."*
