Tue following are among the lecture arrangements ‘hear of any interesting relics which may be found, 
at the Royal Institution, before Easter :—Prof. H. H. 
Turner, a course of experimentally illustrated lectures 
en a voyage in space, adapted to a juvenile auditory, 
to begin on December 27; Prof. W. Bateson, six 
lectures on animals and plants under domestication ; 
Sir John H. Biles, three lectures on modern ship- 
building; Mr. A. H. Smith, two lectures on landscape 
and natural objects in classical art; Dr. W. 
McDougall, two lectures on the mind of savage man; 
Sir Thomas H. Holland, two lectures on types and 
causes of earth-crust folds; Prof. C. F. Jenkin, three 
lectures on heat and cold; Dr. C. W. Saleeby, two 
lectures on the progress of eugenics; Dr. J. A. 
Harker, two lectures on the electric emissivity of 
matter; and Sir J. J. Thomson, six lectures on recent 
discoveries in physical science. The Friday evening 
meetings will commence on January 23, when Sir 
James Dewar will deliver a discourse on the coming- 
of-age of the vacuum flask. Succeeding discourses 
will probably be given by Mr. H. Wickham Steed, 
Dr. H. S. Hele Shaw, Prof. J. Norman Collie, Prof. 
W. A. Bone, Sir Walter R. Lawrence, Bart., the 
Right Hon. Lord Rayleigh, Prof. J. A. Fleming, Sir 
J. J. Thomson, Prof. A. Keith, and other gentlemen. 
Wirn the ordinary issue of The Times on Monday, 
December 1, appeared a special Fuel Supplement of 
sixty pages, in which the various aspects of the whole 
subject of fuel are dealt with. The appearance of 
this supplement to our leading daily journal and the 
general trend of all the articles, is evidence that the 
immense importance of the future supplies of fuel 
must be brought home to the public. Many perhaps 
still fail to realise the rapid depletion of our resources 
which is taking place daily, and the necessity for 
economy in production and economy in application. 
The first step to economy is wider knowledge, and 
whether for the lay reader (if there is such a person 
in this connection), or for the fuel expert, the series 
of articles is admirably adapted to give a general and 
sufficiently detailed account of the whole question. 
The various forms of fuel are described from the 
economic point of view: their production, distribution, 
properties, and the best methods of utilisation detail21. 
Such minor issues as smoke prevention, safety in coal 
mines, the scientific purchase of coal, and other com- 
plementary subjects are dealt with adequately. Nor 
is the future overlooked, when man will have to manu- 
facture his fuel from materials obtainable from exist- 
ing natural sources; and the claims of alcohol, which 
up to the present is but a very minor fuel, are dis- 
cussed at some length. People more particularly in- 
terested in fuel and its commercial application will 
most certainly welcome the appearance of the supple- 
ment, and for others who take an intelligent interest 
in a subject of such general and economical import- 
ance, it furnishes a comprehensive account of the 
whole question. 
Mr. J. Reip Morr, of Ipswich, has forwarded a 
typed letter and printed notices asking for careful 
treatment of ancient remains, to all the brickfields 
and other places in Suffolk where continual excava- 
tions are in progress. By this means he hopes to 
NO. 2301, VOL. 92] 
and for want of knowledge be overlooked or thrown 
away as being of no value. 
In a letter published in Nature of November 13, 
Prof. D. Waterston referred to some excellent radio- 
grams of the Piltdown mandible, and that of a chim- 
panzee which appeared in an October issue of The 
British Journal of Dental Science. There was an 
article upon the radiograms in the same issue, but 
Prof. Waterston was concerned only with his inter- 
pretation of the radiograms themselves. Mr. A. S. 
Underwood, the author of the article, writes to say 
he considers it misleading to state ‘‘that the molar 
teeth in the fragment not only approach the ape form, 
but are in some respects identical. These two molar 
teeth are absolutely human, the difference between 
them and those of the anthropoids in the arrangement 
of the enamel alone being quite unmistakable.” Any 
fresh evidence bearing upon the problem of the man- 
dible is of importance, and it is to be hoped that Mr. 
Underwood will publish at an early date, with illus- 
trations, the evidence he has obtained of ‘‘ unmistalk- 
able’’ characters in the arrangement of the enamel. 
AccorDING to the report for 1912, the authorities 
of the Rhodesia Museum, Bulawayo, are considering 
a scheme for the erection of a new west wing to the 
building, at an estimated cost of about 1400]. The 
curator reports that as much progress as could reason- 
ably be expected, when the funds at his disposal are 
taken into consideration, has been made in the de- 
velopment of the museum during the year under 
review. 
WE have received No. 39 of Dr. Schulze’s Das 
Tierreich, a fasciculus of 210 pages, devoted to that 
group of mialacostracous crustaceans known as 
Cumacea or Sympoda. The author is the Rev. 
T. R. R. Stebbing, who has already contributed to 
this work the memoir on the gammarid amphipods 
(No. 21), and who, as in that fasciculus, writes in 
English. In deference to the usage in the rest of the 
work, Mr. Stebbing surrenders his favourite practice 
of treating all generic names as masculine, and on 
similar grounds he retains the older name Cumacea 
for the group in place of Sympoda. The objection to- 
the use of the former is based on the cancelling of the 
generic term Cuma; but although this bars the 
employment of the family name Cumaide, it does not, 
in our opinion, entail the abolition of the ordinal 
designation. On the other hand, it is a pity that 
some objection could not have led to the abolition of 
such a name as ‘‘ Vaunthompsoniide.”’ The work is 
worthy of the high reputation of its author as a 
specialist in the group of animals with which it deals. 
We have received a prospectus of an interesting 
publication to be issued by the naturalists of the 
Biological Station in Heligoland. The proposal is to 
issue a series of plates of instantaneous photographs 
illustrating the living marine animals and plants of 
the North Sea. The specimen proof that has been 
forwarded with the prospectus is an extremely beau- 
tiful photograph of the jelly-fish, Cyanea lamarcki, 
showing the numerous delicate tentacles in their
