344 THE JOURNAL OF BOTANY 
dealt with the numerous ancient and modern efforts at fungus 
reproduction from the artist’s standpoint: a selection from the 
president's large bolbastion of water-colour paintings of the larger 
ungi was on rps es during the week. Mr. J. Ramsbottom 
read two paper Thursday evening: ‘“ Notes on the History of 
the Olassification of the Phycomycetes” and “Colour Standards.” 
The ee evening Mr. A. D. Cotton showed some interesting 
coloured lantern slides of Clavarie, ia Mr. H. W. Wakefield a 
fine series of lantern slides of the common fungi. Mr. 
E. W. Swanton, of the Haslemere Educational Museum, was

British Mycological Society as a subject for discussion “i ee 
conference of delegates at the British Association. Mr. 
. Ramsbottom read a paper in which the acta attempts to 
provide colour wate were — <a and the 
wing were made :— t schemes which

to come into general use: a primary scheme of about two 
hundred colours would seem are for naturalists except in 
such branches as horticulture, mycology, and ornithology. A fair 
sized, even sample of colour should be provided, anid these should

by modern physical and chemical methods. The colours should 
be named, and where possible — to common natural objects. 
A few hints should be given as to the best way of comparing 
colours, having regard to texture of surface and optical illusions. 
ye a tele rt would be very ie pean and would be practical.

each of the colours of the primary scheme. The discussion 
which followed the paper concerned itself principally with 
the “oa means by which such a scheme could be practically
