great pains he had taken in the matter. He felt sure that all 

 present must have felt that Mr, Wright was very heartily to be 

 congratulated upon the perfection to which he had brought the 

 instrument, and the great efficiency of it for the purposes of class 

 demonstration.

Mr. Hill on behalf of Messrs. Beck exhibited a new form 

 of compressorium, being an adaptation of Mr. Beck's original 

 reversible compressorium by Mr. Richard Davis. The construction 

 and application of this cell were explained by reference to a 

 coloured sectional diagram. 



The President thought this would be found a very useful form 

 of compressorium — a great point in its favour being that it was 

 not very heavy owing to the frame being made of ebonite. Its 

 construction made it very easy to manipulate, and it could be 

 used equally well with either side up. He noticed, however, that 

 the glass of one of the samples exhibited was already broken, 

 and asked if there was any means of preventing this from 

 happening when in use.
