 method has been found quite satisfactory. Particulars were also 

 given of the methods employed when it was required to prepare

At the meeting of the Club held on November 6th, 1908, Pro- 

 fessor Minchin, M.A., President, in the Chair, the minutes of the 

 meeting held on October 2nd were read and confirmed. 



Messrs. Albert H. Quick, William M. Sharp, A. H. John, Max 

 Pink, J. M. Broad, and F. P. Winn -Sampson were balloted for, 

 and duly elected members of the Club. 



Donations of books were announced, and the thanks of the 

 Club voted to the donors. 



The President referred, with regret, to the death, on October

 complete collection of Australian Madreporaria at the Natural 

 History Museum, South Kensington, was formed by him while 

 engaged as fishery inspector to several of the Australian Colonies.

 and were named in 1843. Latterly, much attention had been 

 given to them, especially in regard to sleeping-sickness. Many, 

 but certainly not all, trypanosomes were lethal. The group was 

 entirely confined to the vertebrates. Nearly every known species 

 of vertebrate was the host of a trypanosome, but very many were 

 quite harmless — for example, those found in the blood of the London 

 sewer-rat, and others noticed in various fish, such as bream, pike, 

 tench, eels, etc., taken in the Norfolk Broads. Two distinct 

 genera are recognised — Tryj)anosoma and Trypanoplasma. Of 

 these, the first-named has but one fiagellum, and the second may
