986 PROCEEDINGS OF THE SOCIETY. 



say tliat they were all modifications of the same structure, and that 

 nature had provided a number of corrugations for the purpose of 

 strengthening the scale, rather than plumules which would be of no 

 use whatever so far as they could see. 



The President inquired if Mr. Beck had observed all the markings 

 on the scales of Lepidoptera to be on the under surface of the scale ? 



Mr. Beck said he could not say that they were, but certainly they 

 were so in the Thysanurae. He had not tried the Lepidoptera, but 

 his impression was that they would be found the same.* 



The President suggested that the object of this structure might 

 be to prevent the scales from adhering together, since, looking at it 

 from an engineering point of view, there seemed to be far more of 

 these corrugations than were required for the purpose of strengthening 

 the scales. 



Mr. W. H. Gilburt read a paper " On the Morphology of Vegetable 

 Tissues," the subject being illustrated by drawings, some of which 

 were enlarged upon the blackboard (see p. 801). 



Mr. Stewart said he had listened to the paper with very great 

 interest, as it teemed with original and striking observations, and he 

 was sure that all present would agree that it dealt in a masterly 

 manner with a very important subject, that of how structure was 

 gradually built up. As Mr. Gilburt's views differed so much from 

 those hitherto held on the subject, he thought it would be very 

 desirable that some one should go over the ground again, so as to 

 verify the observations, in which case he would suggest that the cell 

 substance should be taken into consideration as well as the cell 

 outline. 



Dr. Stolterfoth's paper "On a new Species of the Genus Eu- 

 campia " was read by Mr. Stewart (see p. 835). 



Mr. Crisp reminded the Fellows that Mr. Bolton's living organ- 

 isms were always available at the Wednesday Evening Meetings, and 

 had recently been of the greatest interest, including the discoveries 

 that had been made during the vacation by Mr. Levick, Mr. Bolton, 

 and other members of the Birmingham Natural History and Micro- 

 scopical Society, consisting of Leptodora hyalina and Hyalodaphnia 

 Kahlbergensis (see p. 877), Aniircea longispina (see p. 879), and the 

 new genus of Khizopods — Litliamoeba discus, Lankester (see p. 900). 



The visit to this country of an illustrious Ex-officio Fellow of the 

 Society, Professor Haeckel, of Jena, was also referred to, which having 

 unfortunately been made during the recess, had rendered it impossible 

 to welcome him. 



Sec Note to the paper on p. 810.
