37. Syphon.—An improvement on this instrument has 
been made in Paris, by M. Buntem, instrument-maker, 
quai Pelletier, No. 26, so as to save the necessity of suc-

below the bend of the syphon, a ball is blown, forming part

and put into motion by a handle or winch, resembling

the rapidity of its motion, and many other circumstances 3 
but when the paste is properly raised, the operator discovers 
it, by the hissing sound of the fixed air, as it rushes out of 
the machine. It never fails to work well, and requires at
