Feb, 17— Edward Sang, Esq. V. P. in the^ Oiair. The follow- 

 ing communications were laid before the Society : — 



1. Model, Drawing, and Description of a new Nose-pipe for Fire- 

 engines ; having a contrivance by which, in a] moment, the water 

 may be thrown either in a column, as in the common jet, or spread 

 out in a sheet. By Mr Adam Hope, Jedburgh. 



The change from one kind of jet to the other is effected by means 

 of a cylinder, through which two apertures are cut, the one with a 

 round, the other with an elongated opening. The cylinder turns 

 in its place, so that either one or other opening can be used. It 

 was stated, however, that as, during the change, both apertures are 

 for a short time closed, the sudden stoppage of the current would 

 rend the pipes, while, by merely placing the thumb over the open- 

 ing of the common jet, the same effect can be obtained. 



2. Embossed Maps for the Blind; and specimens of printed 

 Music for their use, upon a new principle of notation, applicable 

 to music in general. By Mr James Gall, jun. 24. Niddry Street, 

 Edinburgh. 



The embossed maps, formed by pressing thick paper into cavi- 

 ties prepared in a piece of metal, exhibited the outlines of countries, 

 the courses of the rivers, and the ridges of mountains very distinctly, 

 and seemed to possess the strength requisite for insuring their per- 

 manence. The principle of the new notation of music is to em- 

 ploy numbers referring to the key-note of the tune in!>tead of the 

 live bars and the characters now in use. Mr Gall developed his 

 ideas'on this subject at considerable length, and laid great stress on 

 the saving of room which would result from the adoption of his 

 system, as well as on its greater perspicuity. 



3. Description of a new Process of Engraving in Relief on Cop- 

 per, called Metallic Ectypography. Invented by A. Dembour, en- 

 graver and lithographer, Metz. With Plates. Printed at Metz, 

 1835. Communicated by John Robison, Esq. Couns. Soc. Arts. 



4. A new mode of Heating a Batli, by means of a portable boiler.
