A. D. Waller have been re-elected as representatives 
of the faculty of science. 
A course of four lectures on the gases of the blood 
will be given in the Physiological Laboratory, King’s 
College, Strand, W.C., by Prof. T. G. Brodie, at 
4.30 p-m., on May 31, and June 2, 7, and 9. The 
lectures, which will be illustrated by experiments, are 
addressed to advanced students of the University and 
others interested in the subject. Admission will be 
free, without ticket. 

In recognition of his services to technical education, 
Sir Philip Magnus will be presented with an address 
and Lady Magnus with a piece of plate by the Asso- 
ciation of Technical Institutions on Wednesday next, 
June 2. Mr. J. H. Reynolds, ex-president, will pre- 
sent the address, and Sir William Mather, the first 
president, will make the presentation to Lady Magnus. 
Sir Alfred Keogh, K.C.B., will preside. 
Ir is announced in the issue of Science for May 14 
that the Rensselaer Polytechnic Institute has received 
two substantial gifts recently. Mrs. Russell Sage 
has given 20,o0ol., and Mr. A, T. White, of Broolx- 
lyn, 10,0001. From the same source we learn that a 
trust fund of roool., to be known as the ‘‘ Edward 
Tuckerman Fund,” designed to increase the interest 
in the study of botany among the students of Amherst 
College, has been bequeathed to the college by the 
late Mrs. S. E. S. Tuckerman, wife of the late Prof. 
E. Tuckerman. 
THE governing body of the Manchester Municipal 
School of Technology (University of Manchester) is 
offering not more than ten research scholarships in 
technology during the session 1915-16 at the Man- 
chester School of Technology—one of the value of 8ol., 
three of the value of 75/., and six of the value of sol., 
all with fees remitted. Research may be undertaken 
in mechanical, electrical, or sanitary engineering; in 
any of seven branches of applied chemistry; and in 
textile industries. The scholarships are open to 
graduates of any university in the British Empire, 
and to other persons possessing special qualifications 
for research. Holders of the scholarships will be 
expected to devote the whole of their time to the 
prosecution of the research upon which they are 
engaged. The scholarships may be renewed for a 
second year on the recommendation of the Board of 
Studies. Forms of application and all information 
may be obtained, by letter only, addressed to the 
registrar, School of Technology, Manchester, and all 
applications must be received on or before June 21. 
SOCIETIES AND ACADEMIES. 
LONDON. 
Zoological Society, April 27.—Prof. E. A. Minchin, 
vice-president, in the chair.—Mrs. R. Haig Thomas: 
White-collar Mendelising in hybrid pheasants. The 
paper was based on an examination of the relative 
numbers of dark-necked and ringed male pheasants 
shot during two seasons. The data collected were 
interpreted as providing evidence of the continual 
Mendelising which occurred in the collar of hybrid 
birds.—E. G. Boulenger; Two new species of tree- 
frogs from Sierra Leone.—E. Heron-Allen and A. 
Earland: Foraminifera of the Kerimba Archipelago, 
Portuguese East Africa. Part ii. The contents of 
this part were chiefly systematic, more than 470 species 
and varieties being dealt with, of which thirty-two are 
new to science. 
May 11.—Dr. A. Smith Woodward, vice-president, 
in the chair.—Miss E. A. Fraser: The head-cavities 
and development of the eye-muscles in Trichosurus 
NO. 2378, VOL. 95| 


| vulpecula, with notes on some other Marsupials. 
The 
usual eye-muscles, including a _ well-developed m. 
retractor bulbi, are present in the Marsupialia. A 
large premandibular head-cavity, representing the 
first somite of the head, is found in all the Diproto- 
dontia, and appears to be either absent or of very 
small size in the Polyprotodontia.—Dr. R. Broom ; 
(1) The Organ of Jacobson and its relations in the 
“ Insectivora.’’—Part ii., Talpa, Centetes, and Chryso- 
chloris. In Part i. it was shown that Tupaia and 
Macroscelides and their allies must be separated from 
the typical Insectivores, such as Erinaceus and Gym- 
nura, to form a very distinct and not nearly related 
order—the Menotyphla. In Part ii. it is shown that 
Chrysochloris has no near relationship with either the 
Insectivora or the Menotyphla, and must be made 
the type of a distinct order, the Chrysochloridea. 
Centetes, which has hitherto been regarded as allied 
to Chrysochloris, is more nearly related to Erinaceus, 
though it differs from it in many points, and may later 
have been separated from it. Talpa shows many affinities 
with Erinaceus and a number of differences the value 
of which is at present not apparent. (2) The Anomo- 
dont genera, Pristerodon and Tropidostoma.  Pris- 
terodon, described by Huxley in 1868, is a very near 
ally of Dicynodon, differing mainly in having a series 
of molars which are smooth in front and have a series 
of denticulations behind. The males are tusked, the 
females without tusks. Oudenodon raniceps of Owen 
is a species of Pristerodon; while Opisthoctenodon 
agilis, Broom, and probably also Opisthoct-nodon 
brachyops, Broom, are other species of Pristerodon. 
In 1889 Seeley described two occiputs under the names 
Dicynodon microtrema and Dicynodon (Tropidostoma) 
dunni. As pointed out by Lydekker, these belong to 
the one species, D. microtrema, and other specimens 
in the British Museum show that it differs from 
Dicynodon in the structure of the parietal region and 
in having molars very similar to those of Pristerodon, 
but fewer in number. This species is therefore placed 
in a distinct genus, for which the name Tropidostoma 
must be accepted.—Mrs. H. L. M. Pixell-Goodrich : 
Minchinia: a Haplosporidian. This papers deals with 
the life-history of Minchinia chitonis (Lankester), a 
protozoan parasite of the mollusc Chiton. Hitherto 
this parasite has been considered to belong to the 
Coecidia, but convincing evidence is here brought for- 
ward to show that it is a Haplosporidian. An account 
is given of the multiplication in’ the host by plasmo- 
tomy and sporogony, and a detailed description of the 
development of the very characteristic spores. 
Linnean Society, May 6.—Prof E. B. Poulton, 
president, in the chair.—W. Percival Westell: Some 
bird problems. The author discussed anomalies of 
habit and structure in the order of the list recently 
issued by the British Ornithologists’ Union, and asked 
for help in attempting to clear up some of the facts 
narrated.—Dr. Sarah M. Baker and Miss Maude H. 
Bohling : The brown seaweeds of the salt marsh.—II. 
Their classification, morphology, and ecology. Five 
of the species of Fucoideze common in Britain as in- 
habitants of rocky shores are represented by peculiar 
varieties on the salt marsh. Evidence is brought for- 
ward to show that these forms, although they differ 
widely in their morphology from their rock ancestors, 
‘are to be regarded as adaptational varieties or ‘‘ecads"’ 
in the terminology of Clements. Two general methods 
have been used to study the correlation between the 
morphological peculiarities of the marsh Fucoids and 
the new chemical and physical conditions of their 
environment. The first is to study the distribution of 
natural varieties of one species, and the second to 
examine in detail exceptional cases. These methods 
| have led to the conclusions that dwarf habit is mainly
