with a funnel. Gyzander, (Ibid., Vol. lx. p. 167) abolished the 

 funnel altogether, substituting a wire support which he suspended 

 from a hook. An improvement upon this I exhibited to the 

 members of the Royal Society whereby the suspension is done 

 away with, and the filter made to stand on a table or over a 

 common beaker. The improvement consists first in making the 

 apparatus entirely of glass rod so that nitro-hydrochloric acid may 

 be used, and in shortening one of the suspensory arms so as to 

 allow of the better approach of the jet from a wash-bottle ; and 

 thirdly in fitting one of the arms to a clamp instead of suspending 

 it from a hook as proposed by Gyzander. By the use of this con- 

 trivance the speed of filtration may be hastened four or five fold, 

 and there is not much difficulty in making them.
