SCIENTIFIC COMMITTEE. 



January 5, 1904. 

 Dr. Masters, F.K.S., in the Chair, and twelve members present. 



Proposed Scientific Investigations at Wisley. — The following is the 

 substance of the reply received from the Council to the renewed com- 

 munication addressed to them by the Scientific Committee on this 

 subject : the Council appreciate the desirability of almost all that was 

 urged therein, and they hope that the day is not far distant when much 

 of it may be accomplished. They feel sure, however, that the Scientific 

 Committee will understand that all the desirable things cannot be carried 

 out simultaneously, and that financial considerations compel them to see 

 the New Hall finished and paid for and the Garden properly laid out 

 before embarking on new projects. 



The following reply was drafted and carried unanimously : — " The 

 Scientific Committee beg to thank the President and Council for their 

 reply to their communication, and to say that they are unanimous in 

 regarding the Council's suggestions to secure the establishment of the 

 Hall and of the Garden at Wisley as of primary importance ; they trust, 

 however, that the time may not be far distant before the Council may be 

 enabled to take the recommendations of the Scientific Committee into 

 consideration." 



Pear-shoots diseased. — Dr. Cooke, V.M.H., reported upon some 

 samples sent by Mrs. Cure, of Coombe, Oxon. They were attacked by 

 Cytospora in patches. This fungus would subsequently pass into the 

 Eutypella stage. The trees should be sprayed with Bordeaux mixture at 

 intervals, and if this was unsuccessful the places should be cut out and 

 burnt, and the wounds well protected with tar. 



The Codlin-moth. — Mr. Hooper raised the question as to whether the 

 grease bands, if kept on till the end of May, would catch the caterpillars 

 at that time. It was the opinion of Mr. Saunders that the caterpillars 

 would not have left the Apples in May. Mr. Massee, V.M.H., observed 

 that there is a spring brood in America, but he was not aware of its 

 existence in England, and recommended observations being made to 

 ascertain the fact. 



Camellia Leaf diseased. — Mr. Saunders, F.L.S., showed specimens 

 badly attacked by Pestalozzia Guepini, a fungus which damages the Tea 

 plant. It has been known for the last fifty years. Spraying would only 

 partially arrest it, as the fungus is below the epidermis. 



Orchids malformed. — Mr. Bidgood, Gateshead, sent some excellent 

 coloured photographs of Orchids, showing certain peculiarities : (1) An 

 Odontoglossum citrosmum had the basal flower of a raceme with two well- 

 formed columns, three labella, and eight other perianth segments. The 

 ovarian section had no ovary cells, but numerous clusters of fibro-vascular 

 cords, showing that it was a "multifold" flower, the cords of each
