The illustrationof the areo-pycno meter shows that it differs in construction from theordinary hydrometer chiefly in having a glass bulb, C, placed betweenthe loaded bulb, F, and the expanded portion, B, of the stem; the bulbc is provided with a stopcock, d, and into it is poured the fluid to betested ; the small glass knob, E, serves to balance the instrument whenimmersed in water, which should be at ° C.
