Mr. W. A. Lewis read a paper " On Dr. Hagen's treatment of Atropos 

 pulsatoria and Termes fatidicum," in answer to Mr. Dunning's remarks at 

 tbe previous meeting. 



Mr. Lewis explained tbat be bad made no error of tbe kind Mr. Dunning 

 supposed, and tbat be and Mr. Dunning were at difference not upon facts, 

 but upon the importance attacbed to them; Mr. Dunning had written in 

 tbe language of apology only the same things which Mr. Lewis had written 

 in the language of fault-finding. 



Mr. Lewis said that the difference concerning Atropos pulsatoria was 

 entirely one of words, and continued : —

 transferred to an insect of the genus Clothilla, while in 1861 it had repre- 

 sented an insect of the genus Atropos. Granted at once ; and therefore 

 the Atropos of 1861 is the Clothilla of 1865, which is the proposition 

 Mr. Dmining disputes. The very same 'pulsatoria, Linne,' was in 186J 

 described as an Atropos, and was in 1865 described as a Clothilla, and 

 Mr. Dunning establishes to his satisfaction that the later description is 

 correct. For the purposes of this argument, I will agree with him. What 

 if it is? That concession leaves the facts unaltered, and only makes the 

 indefinite definite in that it fixes the error as having been in 1801, whereas
