8 PROCEEDINGS OF THE 



The specimen in transverse section of an area of 20 x 35 cm. 

 shows a uniform structure of most beautifully petrified tissue, 

 which appears to be quite unlike any known fossil. Micro- 

 photographs were exhibited showing the details of the tissues, 

 which, in many respects, are like a giant phloem. The name 

 Vectia luccomhensis is proposed, and the exhibitor asked for 

 suggestions as to its affinity. 



Dr. D. H. Scott, Sec.R.S., F.L.S., and Prof. Margaret Benson, 

 F.L.S., having spoken, the exhibitor replied. 



Dr. H. Deinkwater, T.L.S., gave a lantern-demonstration 

 of " Brachydactyly as au example of Mendelian Inheritance." 

 Some wax models, and a large number of photographs, radio- 

 graphs, and 69 lantern-slides were exhibited. (Abstract, see 

 p. 40.) 



The Eev. T. R. E. Stebbing and Mr. W. S. Eowntree, F.L.S., 

 contributed some additional observations, and the author replied. 



February 18th, 1915. 

 Prof. E. B. PouLXoy, F.E.S., President, in the Chair. 



The Minutes of the General Meeting of the 4th February, 

 1915, were read and confirmed. 



Mr. James Melville Macoun, C.M.G., was elected a Fellow. 



The President announced that the Council had decided to hold 

 the remaining six General Meetings of the present session at 

 five o'clock in the afternoon. 



The General Secretary read a letter from His Excellency 

 Count AVrangel, enclosing a photograph of a memorial recently 

 erected by the Eoyal Academy of Sciences, Stockholm, in the 

 Swedish Cemetery at Woking (Brookwood), consisting of a head- 

 stone of Swedish granite, inscribed " Kungliga Vetenskapsaka- 

 demien reste virden 1914. Daniel Solander * 1733 tl782." 

 Allusion was made to the striking portrait of Solander by John 

 Zoffany in the possession of the Society, 



A cordial vote of thanks was passed to the Swedish Minister 

 for this very acceptable gift. 



Mr. Harold Wager, F.E.S., F.L.S., then gave an account of 

 his recent researches upon "The action of Light upon Chlorophyll," 

 illustrating his remarks with lantern-slides, many being auto- 

 chromes. He stated that the chemical changes produced by light 

 on the green leaf, sugar and starch being evolved from carbon 

 dioxide and water, are still obscure.
