% Strength ofPFine and other Bottles. — M. Collardeau ha<i,WJi-^ 

 striicted a machine for the purpose of trying the strength of wine? 

 bottles. It has been presented to the Acaddmie des Sciences, ana 

 reported upon by MM. Hachette and D'Arcet. The bottle to be triefl"! 

 is held at the neck by means of a lever, having three branches, whicfc'

 nected by means of pipes, with a forcing-pump, the pipe having a" 

 cap furnished with leather, which is firmly held down by the appa-^ 

 ratus upon the mouth of the bottle ; the pressure upon the parts 

 here increases with the pressure of the water within the bottle. 

 Besides the pump, levers, and connecting pipe, there ia^alscLa mano-
