from the sampler is placed in the apparatus through a 

 lateral orifice. As soon as the solid cone revolves, it 

 is, by a well-combined lever, P, worked by hand, forced 

 against the outer cone, the lower part of which is a 

 funnel-shaped hopper, H, connecting with the flask, F, 

 having the same number and serial divisions as the 

 sample being crushed. In connection with the inte- 

 rior of the machine is a rubber appliance, R, its capac- 

 ity being 80 c. c, filled with water; by pressing it the 

 water is forced between the inner and outer cones and

There are special frames or baskets to hold twenty 

 flasks, each compartment of which is numbered. The 

 flasks are carried to a table where 1.5 c. c. of subacetate
