154 Crossland : The Study of Fungi in Yorkshire, 



(2) . On Nuclear Division in the Hymenomycetes. (Ann. 



Bot., 1893). 



[Discovery that nuclear structure and mode of division 

 — Chromosomes and spindle figure — are the same as in 

 the higher plants. The fusion of two nuclei in the basi- 

 dium is also here described and figured for the first time]. 



(3) . On the presence of Centrospheres in the Fungi. (Ann. 



Bot., 1894). 



[Further observations in Nuclear structure and division 

 with description of division centres which play an impor- 

 tant part in nuclear division in some plants]. 



(4) . On the structure and reproduction of Cystopus eandidus, 



(Ann. Bot., 1896). 



[Contains an account of structure of nuclei, of division 

 and sexual nuclear fusion in this fungus]. 



(5) . The Nucleus of the Yeast plant. (Ann. Bot., 1899). 



(6) . The Sexuality of the Fungi. (Ann. Bot., 1899). 



[An account of the researches on this subject, with a 

 critical review of some explanations put forward by 

 ^ Dangeard and others.] 



(7) . On the Fertilization of Peronospora parasitica. 



Papers also on the Life History and Sexuality of 

 Polyphagus Euglence, have also been read before Section K. 

 of the British Association, and at the Union Fungus Forays. 



Mr. Wager has occupied several important posts in con- 

 nection with the British Association, among them being Presi- 

 dent of Section K at the South African Meeting. He was for 

 some time President of the Leeds Naturalists' Club ; Chairman 

 of the Botanical Section Y.N.U., Examiner in Botany in the 

 University of Cambridge, Victoria (Manchester, Liverpool, 

 Leeds), and Durham. Some time Lecturer in Botany in the 

 Yorkshire College — now Leeds University, etc., etc. 



The economic aspect has forced itself upon the attention 

 of Botany professors and others interested. The potato 

 epidemic which broke out in the forties, set investigators on 

 the track of the cause of these destructive plant diseases. The 

 life-histories of many parasitic fungi which prey upon farm, 

 orchard, and garden produce, have since been investigated 

 with a view to reduce their ravages. 



Dr. W. G. Smith, Leeds University, informs us that the 

 Agricultural Department connected with the University has 

 carried on experiments in this direction since 1898. Among
