wide bearing of the advance. In these latter years the 
old circumscribed course has blossomed like the rose: 
everywhere “zoology” has come to be supplemented by 
economic zoology, agricultural zoology, medical zoology, 
forest entomology, veterinary zoology, protozoology, helmin- 
thology and the like. Outside the Universities the same 
process is to be seen in the formation of associations of 
applied zoologists, and in the publication of reviews of 
economic entomology and journals of applied zoology. 
To the writer this new and close contact of zoology with 
human affairs seems to be the most striking and promising 
of recent developments of the science. Whether it originated 
with the zoologists themselves, or was impressed upon them 
by the force of public opinion, matters not, now that the tide 
is in full swing ; but this is certain, that the more the farmer, 
the veterinarian, the forester, the man of medicine demand 
of the science of animal life, the more will zoologists respond 
to an appeal which can only result in increased good to the 
race of man. 
A striking case of the intelligence of a Chacma Baboon 
was reported recently in these pages (p. 63); but Mr J. E. 
Harting writes to draw attention to even more wonderful 
instances related by Mr F. W. Fitzsimons in the first 
volume of his Natural Hestory of South Africa. Of these 
Mr Harting says the most remarkable is that of an individual 
captured when half-grown and trained to push his lame 
master in a trolley, to fetch and carry, to draw water, and 
even, under direction, to work the levers of the railway 
signals in his master’s charge. But to us it seems that 
directed and imitative energy stands on a different plane 
from the original efforts of an untaught mind. 
An appropriate memorial to the late W. Denison Roebuck 
appears in the Journal of Conchology in the form of a “ Census 
of British Land and Freshwater Mollusca” for which he was 
mainly responsible, Here, at a glance, the distribution of 
the 115 species “authenticated” from Scotland may be seen, 
and the lists, while giving evidence of much careful collecting,
