prudent investment for the future. The scale upon which the 
building has been carried out will be appreciated when it is 
explained that there is accommodation for 150 general elementary 
students, and for the higher grades in proportion. The con¬ 
venience of the site, close to the other scientific departments of the 
University, is of course quite evident, but we cannot help thinking 
that the Botanic Garden would have been found in the long run an 
even more appropriate spot. 
Externally the new school, is as pleasing to the eye as its 
interior arrangements are acceptable to the Botanical instinct. The 
Architect, Mr. W. C. Marshall, whilst conceding every scientific 
requirement has at the same time, with rare skill, produced a 
dignified and beautiful building worthy of the purpose it is to 
fulfil. 
It only remains to be said that many Botanists from all parts 
of the country were able to accept the hospitality of their 
Cambridge confreres and be present at the opening, and that they 
were delighted to see that Botany—-the Cinderella of the Sciences 
—had at last received at the hands of the University that recogni¬ 
tion which she has so long claimed. The very pleasant “house¬ 
warming” which followed the more formal ceremonial was the 
occasion for many hearty congratulations to Professor Marshall 
Ward and his Colleagues on the realisation of their aims, and of 
good wishes for the continued prosperity of the School.

A PROBABLE PARASITE OF STIGMARIAN ROOTLETS. 
By F. E. Weiss, D.Sc. 
[With Figs. 66 and 67.] 
S OME time ago I had noticed in a Stigmarian rootlet the for¬ 
mation inthe middle cortex of a certain amount of secondary 
tissue (see fig. 66, s.t.), which was apparently developed under the 
stimulus of some injury to the rootlet. The nature of this injury 
puzzled me a good deal and I was particularly at a loss to explain 
the presence of a curious enlarged cell (h.c.) which had forced its 
way to the surface through the outer cortex. I had consequently 
put the section on one side hoping that further specimens of a 
similar kind might enable me to clear up this difficulty. 
In the meantime a paper by F. W. Oliver has appeared in this
