PAPER READ. 



The meeting was devoted to a microscopical demonstration by 

 Mr. A. Schulze. There were six microscopes on the table — 

 viz., one large binocular of Ross & Co., with low and high power 

 prisms, complete illuminating, drawing, and measuring apparatus, 

 and with Ross' and Powell's object glasses; one fine binocular 

 of James White's,, one binocular of James Swift's, and three 

 monoculars on the Hartnack model. Three of the instruments 

 on the table were kindly lent by Mr. James Brown, St. Vincent 

 Street. There were five of How's, and one of Swift's microscope 

 lamps on the table, as well as a splendid Dallinger lamp having a 

 wick an inch and a-half broad, copper chimney, large bull's-eye 

 condenser and universal motions. Among the objects exhibited in 

 the course of the evening were the following : — The circulation of the 

 blood in the web of a frog's foot, under a power of 330 diameters ; 

 the rotation of the chlorophyll in the cells of Anacharis Canadensis, 

 under a power of 800 diameters ; the yeast plant 900 diameters ; 

 human blood, 1200 diameters; living infusorise, animal parasites, and 

 a number of beautifully injected preparations of human kidney, 

 spleen, and lung. Among the more remarkable preparations 

 exhibited were the following: — Moller's Typenplatte, containing 160 

 diatoms, the name of each species being photographed on the slide ; 

 several beautiful slides of diatoms, arranged by Arthur C. Cole, of 

 Liverpool ; a splendid cornucopia and flowers, arranged from the 

 scales and hairs of butterflies and from diatoms. There were also a 

 splendid set of botanical and entymological preparations exhibited. 



A vote of thanks was given to the gentlemen who had brought 

 forward such a fine series of microscopes and slides.
