THE programme of the annual conference of the 
Child-Study Society, to be held in the University of 
London on May 9-11 inclusive, is now available. 
The subject arranged for discussion is the health of 
the child in relation to its mental and physical 
development. The presidential address will be 
delivered on May c by Sir James Crichton Browne, 
F.R.S. Among papers to be read at the conference 
may be mentioned :—The influence of defects of hear- 
ing in relation to the mental and physical development 
of the child, by Dr. J. Kerr Love; the influence of 
sick nursing. In August the courses will be con- 
cerned with practical mathematics and mechanics, 
handrailing, metal work, and rural science. Though 
most of the courses will be held in Dublin, some 
have been arranged for other important centres. 
Teachers desiring to take advantage of these courses 
must fill up and return the appropriate form of 
| application so as to reach the oflices of the depart- 
ment, Upper Merrion Street, Dublin, not later than 
April 30. 
ATTENTION was directed, in our issue of April 4 
(vol. Ixxxix., p. 129) to the opening to-morrow of the 
spinning section of the textile department of the 
University of Leeds by the Master of the Cloth- 
workers’ Company. The new extension is intended 
to afford facilities for instruction in the principles 
and theory of the manufacture of worsted yarns on 
the Continental system. To secure the most suitable 
equipment for this branch of technological teaching, 
textile institutes, spinning works, and conditioning 
laboratories in Belgium, France, Germany, and 
Switzerland were inspected, and a full inquiry was 
made as to the commercial value and technical nature 
of this system of worsted yarn construction. The 
extension has been designed by Mr. Paul Waterhouse, 
and erected‘at a cost of 5oool., making a total amount 
for technical education in the textile industries and 
dyeing departments of the Leeds University.

distinctive peculiarities of this species, which, on 
account of its great scarcity, had never been satis- 
factorily classified since it was described by G. Cuvier 
in 1825 from a coloured illustration of a specimen 
living at that time in the Barrackpoor Menagerie.— 
F. E. Beddard: Species of tapeworms of the genus 
Inermicapsifer obtained from the hyrax, with notes 
on the genera Zschokkeella and Thysanotenia. An 
account of the structure and characters of the species 
was given, together with the description of a new 
genus and two new species.—Dr. Bashford Dean:

contained some further observations made by the 
author in June, 1911, supplementary to his previous 
communication published in 1906, and dealt with the 
coloration, size, and age of the specimens. Détails 
of the rate of growth of this species were also given, 
with notes on their method of breathing, their food,
