Mr. Sidebotham explained how, by the use of coloured glass before Ihe lens, the 

 colour of the insect might be neutralized, as in the case of yellow a light blue glass 

 would give green, which colour enabled the photographer to work successfully. 



The President explained how, wiih a half-plate lens, he had succeeded in obtaining 

 the natural size negative of the insect before the meeting. After sundry attempts 

 which all produced reduced figures of the insect, he determined to try what a much 

 greater elongation of the camera would do, and immediately made a long box without 

 ends, fixing the lens end of the camera in one end of it, and drawing the back part 

 out; he got a full-sized figure without further trouble. 



Mf. Sidebotham called the attention of the meeting to a series of carefully 

 executed diagrams on the table of the plumules and scales of Pieridse, made by him- 

 self to illuslrate a paper by his friend Mr. Walsou, aad observed that in no case had 

 they found any plumules upon female specimens. 



An interesting conversation ensued, in which Mr. Sidebotham gave much valuable 

 information. ' 



The President distributed a number of copies of his " Coleopteia of the District 

 around Liverpool. Section I. Geodephaga. 1861."
