IMR. W. CASSIE ON THE EFFECT OF TEMPERATURE ON 
II. Liquids. 
The apparatus for liquids consisted essentially of a quadrant electrometer immersed 
in the liquid. 
The heating was done by a water bath; and on account of the highly inflammable 
character of some of the liquids experimented upon, the water was heated in a 
separate vessel at a distance, from the top and bottom of which pipes went to a and d 
in flg. 7. The hot water was pumped through in the direction dch a. 
The provision for the insulation was on a similar principle to that adopted in the 
case of solids. Each quadrant was supported by a long stiff rod, the upper part of 
which was fixed in a varnished glass tube. These four glass tubes were separately
