and which, when injected, die. Concerning the place of the East Coast 
fever parasite in protozoology, he thinks the proposition justifiable to 
separate it from Piroplasma, and to substitute a new generic name 
" Theileria,'' as suggested by Better court. 
Ordinary Monthly Meeting. 
July 20, 1910. 
The President, S. S. Hough, Esq., F.E.S., in the Chair. 
The President announced that Eev. E. Goetz and H. G. Fourcade 
were recommended to the Society for election as Ordinary Fellows; and 
that they have put in nomination for election as Honorary Fellow, 
Sir Walter Hely-Hutchinson. 
Miss Bleek, Messrs. P. J. du Toit, and Dr. F. Engelenburg were 
nominated for Ordinary Membership. 
Factorizable Continuants," by Thomas Muir, LL.D. A short paper 
with the above title was presented to the Society more than six years ago, 
and appears in the Transactions, vol. xv., pp. 29-33. Attention has now 
to be drawn to the fact that the fundamental theorem of this paper has by 
some oversight just been published as a fresh discovery of Professor 
Metzler's in the British Association Eeport (Winnipeg Meeting), p. 390. 
The identity of the two results is seen on changing the letters n, a, b, c of 
the earlier paper into 7i + l, r, «a, a(/(3-a). 
" The Effect of the Electric Discharge on Water Vapour," by E. Jacot. 
Experiments leading to results not in agreement with those of M. Henry 
[Journal de Physique, Jan., 1909, pp. 33-38), viz. : that cathode rays are 
produced in vacuum tubes containing water vapour at pressures higher 
than is the case in tubes containing air. The electric discharge brings about 
reduction of the vapour. In tubes containing metallic electrodes, the 
reduction, if started by the passage of a discharge, will even proceed quite 
independently of the discharge. In electrodeless tubes the final steady 
state of pressure of electrolytic gas depends on the pressure under which 
the water vapour is initially admitted, and is affected by the presence of 
colouration on the glass due to chemical action by cathode rays. 
Note on " Verneuk Pan," by A. W. Kogers, Sc.D. Verneuk Pan is a 
flat surface cut in shale and partly covered with sandy mud which forms 
a thin layer only. It is a striking example, being over 100 square miles in 
area, of numerous pans on the Dwyka formation in the north of the 
Colony. It has an outlet over a bar of hard dolerite. The formation of 
this and other pans which lie in the course of streams was probably due in
