‘a greater compass than the double bass, and can be performed 
upon with as much facility as the violincello ; and as its tone is 
much less powerful than that of the double bass, it will be found 
a most desirable acquisition in chamber concerts. The Society 
awarded its gold Isis medal to Mr. Barraud for this invention. 
Mr. G. Rhodes’s Warp Drier.—The warp is wound upon a 
sort of reel in a spiral manner, leaving spaces between each coil 
for the air to enter and dry the warp: it will be found very use- 
ful to woollen weavers, as it enables them to dry their warps in 
the house instead of exposing them at full length along the 
highways, &c. as usual. The Society voted its silver Isis medal 
and 10 gumeas to Mr. Rhodes for this invention. 
Mr. Donovan’s British Cured Herrings—Mr. Donovan havy- 
ing resided for a long time in Holland, and witnessed the methods 
used there in curing their celebrated herrings, was at the pains 
of repeatedly bringing over Dutch fishermen and curers to 
instruct the Highland fishermen in those processes, and has 
completely succeeded therein. The Society has awarded its 
premium of the gold medal, or 50 guineas, to Mr. Donovan for 
this laudable undertaking. 
Mr. Thomas Taylor’s Repeating Alarum.—This instrument 
has been found of great service in the Royal Observatory at 
Greenwich, in giving the astronomer timely warning of the 
passage of certain stars, &c. either by day or night, and thereby 
affording him opportunities of making observations which might 
otherwise be lost. The Society voted the sum of 15 guineas to 
Mr. Taylor for this invention. 
Mr. Richard Green’s Gauge, or Plough, for cutting Leather 
Straps, &c.—This instrument will be found useful, to saddlers, 
bridle cutters, harness makers, &c. as it performs its work with 
great accuracy and expedition, and the edge of the knife is never 
injured by coming into contact with the cutting board. The 
Society awarded its silver Isis medal to Mr. Green for this 
imvention. 
Mr. Wilham Feetham’s Chimney Sweeping Apparatus.—By 
‘the introduction of a door into the flue, as near the top of the 
@himney as convenient, with a pulley affixed to it, that part of 
the. chimney below the door may be conveniently swept by 
means of a line and brush, with an iron ball in a swivel affixed 
thereto; andthe part above the door may be cleaned by another 
brush attached to a flexible handle ; and in most cases without 
the use of climbing boys. The Society adjudged its silver 
medal to Mr. Feetham for this invention. 
Mr. Fayrer’s Clock.—This is an improvement on the three- 
' wheeled clocks recommended by Dr. Franklin and Mr. Fergu- 
son, by which they will go longer without winding up, and will 
continue in action whilst. winding. The Society voted its silver 
Isis medal to Mr. Fayrer for this invention.
