PEOCEEDINGS or THE 



cytology. It will be argued that it is impossible, at present, to 

 frame a scheme which will include all the known facts, without 

 making both sexes " heterogaraetic," and consequently assuming 

 that some form of selective fertilization must occur. 



Evidence in favour of the occurrence of something tantamount 

 to selective fertilization will be produced in the case of hybrid 

 pheasants, where the preponderance of males over females cannot 

 be accounted for by a selective death-rate occurring at any but an 

 •exceedingly early period of development. 



The discussion was continued by the President, Mr. L. Don- 

 oaster (visitor). Prof. W. Bateson, F.E.S., Mr. F. H. A. Marshall, 

 Mr. J. T. Cunningham, Prof. E. W. MacBride, E.E.S. (the last 

 three being visitors), Prof. E. A. Minchin, F.R.S., Dr. W. T. 

 Caiman, and Prof. G. C. Bourne, F.E.S., Sec.L.S., the author

April 3rd, 1913. 



Prof. J. Stanley G-AEDiisrER, M.A., F.E.S. , Vice-President, 

 in the Chair. 



The Minutes of the General Meeting of the 6th March, 1913, 

 •were read and confirmed. 



Mr. James Ebenezer Black was admitted a Fellow. 



Miss Grace Bigby, B.Sc. (Lond.), was elected a Fellow. 



Mr. Eobert Paulson, F.E.M.S., was proposed as a Fellow. 



The Vice-President in the Chair remarked that it was some- 

 times pleasant to break away from formal routine, as in the case 

 of one who had been a Fellow since 1868 and a Secretary since 

 1880; he therefore suggested that all present should join in 

 wishing Dr. Jackson many happy returns of this, his birthday, 

 long life, and continued health. 



The General Secretary, in acknowledging this suggestion and 

 its cordial adoption by the meeting, said that the motion had taken 

 him by surprise, so that he was not prepared adequately to express 

 his thanks and pleasure ; he was glad to recall that by the favour 

 ■of the Fellows he had been continued in his ofiice for a longer 

 period than any of his predecessors, and having devoted many of 

 his best years to the service of the Society, — a service in which he 

 delighted — he hoped still to be able during the remainder of his 

 official life to advance the welfare of the Linnean Society of 

 London.
