Powell & Lealand's large binocular instruments, with all the newest 

 accessories. This is probably the finest microscope ever imported 

 into Canada. Other instruments were contributed by Dr. J. B. 

 Edwards, Messrs. James Ferricr, jr., A. S. Ritchie, D. B. Scott, 

 R. McLachlan, and J. F. Whiteaves. Mr. Scott shewed the 

 circulation of the blood in the web of the foot of the Shad Frog, 

 also beautiful living examples of Vorticella campanularia, V. ne- 

 hulifera, Stentor cceruleus, and other infusoria from his own aqua- 

 rium. Mr. A. S. Ritchie illustrated details of insect structure, 

 especially elytra of exotic beetles, and wings of tropical butterflies 

 and moths. He also exhibited some good diatom slides, and a 

 photograph, of microscopic animals and plants from a pond 

 at Leytonstone (near London, England) by H. C. Richter. 

 Mr. R. McLachlan shewed German examples of trichina spiralis, 

 and Mr. Whiteaves some choice polariscope objects, while Messrs. 

 Young and Ferrier contributed a number of fine slides by 

 English preparers. The string band of the P. C. 0. Rifle Brigade 

 was in attendance and performed a choice selection of music during 

 the evening. A little after 8 o'clock, H. R. H. Prince Arthur, 

 attended by Lieut. Picard, entered the building, where he was 

 received by a deputation of tho senior officers of the society. The 

 following address to H. R. H. was then read by the acting presi-
