kept it till the wound healed, and then presented it for the reward. After 

 spawning time, between June and July, it is intended if possible to capture 

 one of the fish and preserve it. At present the weight of the grilse ia 

 estimated at from 4 to 6 pounds. 



The formal business of the evening having now terminated, the Fellows 

 adjourned to the large room upstairs where, agreeably to notice, a 

 Microscopical Exhibition was to be held. 



This Exhibition, like its predecessor, was very complete in its display 

 of Microscopes, accessory apparatus and objects. The large upper room 

 of the Museum was fitted up for the purpose, and six first-class instru- 

 ments, made respectively by Varley, Ross, Beck and Beck, and Pritchard, 

 were exhibited. Also two Microscopes, by Oberhauser, three of Binocular 

 construction, by Beck and Beck, with a number of minor instruments. 

 Many of the former were fitted up with all the modern accessories and 

 improvements. 



The doors were thrown open to visitors at 8 o'clock, and as each Fellow 

 had the privilege of introducing three ladies the room was soon filled with 

 spectators. * 



The series of specimens brought before the meeting was so extensive 

 "and interesting that parts of it might properly afford material for several 

 distinct notices. The circulation of blood in the animal and sap in the 

 plant were well displayed. A number of suitable objects were shown 

 under polarised light, with an extra large Prism, which, besides assisting 

 in the accurate determination of structure, produces most beautiful effects. 

 Not the least interesting objects were a series of thirty sections of Colonial 

 "Woods, together with Foraminiferae from the Mediterranean and the 

 Coast of Australia, Polycystina, from Barbadoes (seen opaque and trans- 

 parent), and also a large number of entomological and vegetable prepara- 

 tions. A specimen of the cast skin of Aphis destructor, and a Chrysalis 

 were shown by means of Beck's opaque Disc -revolver, by which arrange- 

 ment as many as five sides of a cube can be examined with ease. 



In addition to the various objects shown under the Microscopes were 

 thirty-one enlarged microscopic photographs of Diatomacese, printed on 

 albumenized paper. The negatives of this beautiful series were taken by 

 !Dr. Maddox. On the same board was exhibited a photograph of micros- 

 copic crystals from the Human Breath, showing the chemical constituents 

 of the exhalations thrown off from the lungs. This photograph was taken 

 from a drawing by Mr. Lens Aldous, the celebrated Microscopical artist. 



To illustrate the infinitesimal beauty of these photographs, naturstl 

 specimens of the diatoms were shown under the Microscope, exhibiting 

 striae from 40,000 to 100,000 in the inch. 



Some of the above objects were beautifully prepared by Mr. E. D. 

 Harrop, of Launceston, who very kindly sent them for exhibition. The 

 Fellows present who had Microscopes were Mr. Abbott, Mr. Abbott, jun., 

 Dr. Agnew, Mr. M. Allport, Mr. E. Atherton, Col. Chesney, ]\Ir. 

 Johnston, Mr. Napier, and Mr. IStone. Mr. Roblin had two Microscopes 

 under his charge, and also exhibited, with great success, the Magnesiuiti 

 Light. 



The Exhibition was continued until about 10 o'clock to the great 

 Satisfaction of the numerous visitors.
