was at once granted, and Mr. Sievewright, M.A., was appointed to 
superintend their exhibition. Mr. C. J. Whiting, the Brighton Post 
Master, also accorded the project his warm approval; and a staff of 
energetic, obliging, and painstaking clerks from the head office on the 
Old Steine were present to assist in the working, under the superin- 
tendence of Mr. G. Field. Numerous and varied were the messages 
sent from one end of the room to the other during the evening. One 
of the most compact and wonderful of all the telegraphic instruments 
appeared to be that by which messages are sent and received 
solely by sound, no other means of indication being afforded. This 
instrument required a skilful and attentive operator, but the practised 
ear seemed to overcome the apparent difficulty and transcribe the 
message with the greatest ease and facility. -Telegraphy as applied to 
railway signalling was also shown. 
An automatic spectroscope, constructed by himself, was shown 
by Mr. H. Pratt; amicro-spectroscope by Mr. Mitchell. In the 
Saloon Mr. F. E. Sawyer arranged an exhibition of meteorological 
instruments, charts, and diagrams, including a self-registering rain 
gauge, invented by Mr. E. Rowley. 
Galvanic batteries were exhibited by Dr. Badcock, and 
Messrs. J. J. Sewell and B, Lomax ; fine equatorial by Mr. D’Alquen ; 
kaleidoscopes by Messrs. G. Nash and Haselwood ; graphoscopes by 
Messrs. Rowsell and Treacher. 
_ In the Corridor there was exhibited a magic lantern at intervals 
during the evening. The slides were chiefly natural history objects, lent 
-by Mr. C. Baker, of Holborn. They were exhibited by Mr. G. Nash, 
and explained and remarked upon by Mr. T. W. Wonfor. 
In the Saloon, South Drawing Room, Corridor, and Banqueting 
Room were also arranged various objects of Natural History and 
Archeology, the most noteworthy being :—Very fine carpological 
collection, consisting of some hundreds of fruits, about sixty speci- 
mens of Canadian woods, and a collection of Japanese plants, in pots, 
by Mr. Hemsley ; two brass Persian lavers, about 400 years old, from 
a Persian temple, candlestick, lamp, and coffee pot, all exquisitely 
engraved, and five cases of Indian moths and butterflies, by Mr. Wills ;
