Museums is devoted to various groups of Malay 
aboriginal tribes, Mr. C. B. Kloss communicating a 
number of measurements and photographs of Bidu- 
anda (Mantra) of the Ulu Kenaboi, Jelebu, while Mr. 
J. H. Evans furnishes notes on the same tribe, as well 
as others relating to the natives of Lenggong, Upper 
Perak, and yet others on those of the Ulu Langat, 
Selangor. The Lenggong aborigines, although de- 
rived from a Negrito stock, speak a Sakai dialect, 
like the pure (Negrito) Semang of Grit, from which, 
however, they differ by their lighter colour. Like 
many of the other native tribes, they object, however, 
to be called either Semang or Sakai, the reason for 
this being that both these names are commonly used 
bv ‘he Malays as terms of reproach. The people of 
the Ulu Langat and Ulu Kenaboi, who are all of one 
race, are more or less pure-bred Sakai. 
In the issue of L’Anthropologie. for November- 
December, 1913, Mr. O. G. S. Crawford discusses 
the question of prehistoric trade between England 
and France. He directs attention to the discovery in 
southern England of certain stone celts, vases, and 
bronze palstaves of Continental types. These seem to 
have reached this country from the Cotentin penin- 
sula, in which prehistoric remains, especially hoards, 
are abundant. In support of these views he further 
considers the position of sites in this country sacred 
to the worship of St. Catherine. These lie in the 
western half of our south coast, but are wanting in 
the eastern half.. He suggests that her wheel is a 
symbol of light connected with a Gaulish divinity, 
known as Lhud in Britain, and Nuada in Ireland. 
The cult of St. Catherine, not known in England 
before the Norman Conquest, is believed to have 
arisen in sites sacred to her predecessor, the olden 
Gaulish deity. 
Ar a recent meeting of the Prehistoric Society of 
East Anglia, Mr. J. Reid Moir announced the dis- 
covery of a flint workshop floor in Ivry Street, St. Albans. 
An excavation for building purposes disclosed one 
foot of surface soil and two feet of fine stoneless sand. 
Then came the prehistoric stratum, containing flint 
cores and flakes, calcined flints, fragments of pottery, 
quartzite pebbles used as hammer-stones, and animal 
bones, some of which had been cut through, and, for 
some purpose, incised. Under this stratum lay fine 
sand to an unknown depth. Most of the flints were 
in the form of long flakes, patinated of a light blue 
colour. One had been trimmed for use as a scraper, 
and though it is difficult to attribute these specimens 
to any particular culture, Mr. Moir, judging from the 
length of the flakes, is inclined to assign them to the 
Magdalenian period. The bones found were those of 
a small sheep, teeth of an ox, and a tibia, probably 
that of a red deer. It is curious that another ‘‘find”’ 
of flints recently discovered at Ipswich is assigned to 
the Aurignacian period. If this attribution be 
accepted, we find remains of two Paleolithic periods 
within the confines of this town. 
In Meddelelser fra Kommissionen for Havunder- 
sogelser, Fiskeri, Bd. iv., we have two papers dealing 
with the biology of the plaice. The first of these is 
NO. 2320, VOL. 93] 
NATURE 
169 
by Dr.-A. C. Johansen, on the immigration of plaice 
to the coastal grounds and fiords on the west coast of 
Jutland, and contains some interesting data on’ the 
changes in frequency of young plaice from one year 
to another in the shore zone. The second paper is by 
B. Saemundsson, on marking experiments carried out 
in the neighbourhood of Iceland. These experiments 
yield some results of interest, though they are not 
altogether satisfactory on account of the small num- 
bers of fish dealt with. It is interesting to note that 
by far the largest number of recaptures were made 
by English trawlers from Grimsby and Hull. In the 
same volume there is a useful report by P. L. Kramp 
on fish-eggs and larve collected in 1909 in the Lange- 
lands Belt. 
In the March number of the Journal of Economic 
Biology (of which we notice that Mr. W. E. Collinge 
is now sole editor) Mr. A. A. Girault, of the Univer- 
sity of Illinois, completes his ‘‘ Preliminary Studies on 
the Biology of the Bed-bug (Cimex lectularius),” 
giving details of successive pairings and generations 
with statistics as to the periods of feeding and the 
numbers of eggs laid by the females under observa- 
tion. In summarising the reactions of bed-bugs to 
various stimuli, Mr. Girault states that the insect’s 
usual behaviour of shunning light may be abandoned 
under the stronger stimulus of hunger. ‘‘ Bed-bugs 
will visit a host in daylight or in bright artificial 
lights when hungry . . . as soon as the food-stimulus 
is neutralised by engorgement, however, the negative- 
ness to light becomes dominant again, and the insect 
runs off to hide itself.”’ 
Tue February issue of the Bulletin of Entomological 
Research contains, as usual, systematic papers of.con- 
siderable interest. Mr. F. V. Theobald writes on 
African Aphididz, and is able to record ‘‘ only thirty- 
five species for the whole African continent, about the 
number one can collect in a single afternoon in one’s 
own garden in England,’’ and several of these have 
clearly been introduced with nursery stock from 
Europe. Prof. R. Newstead describes new Coccide, 
and Mr. E. E..Austen new Tabanidz, both papers 
being. well illustrated. Of considerable interest is Mr. 
R. B. Woosnam’s report on a search for Glossina 
(Tsetse-flies) on the Amala River in the southern 
Masai. Reserve, of which he is game-warden. In a 
definitely restricted area along the river and its tribu- 
taries at more than 5000 ft. altitude he found a 
Western species, G. fusca, hitherto unknown in the 
East African Protectorate. The cattle, sheep, and 
goats of the Masai suffer very little from tsetse-borne 
disease, either because the people manage to avoid 
the fly-belt when moving their stock, or because only 
a very small proportion of the flies are infective. 
By publishing reports for two successive years in a 
single cover, the Felsted School Scientific Society is 
enabled to reproduce some of the prize photographs 
taken by its members, the report for 1912-13 conse- 
quently presenting a more than usually attractive 
appearance. Particular interest attaches to the photo- 
graphs of a young cuckoo and its foster-parent, a 
whitethroat.
