“variation in development depending on the absence or 
presence of suitable stone for making arrow-points. 
The wooden point still survives, but only sporadically ; 
the stone point has disappeared, but the leaf-shaped 
iron point used by some of the Kavirondo, Nandi, and 
also found among the Tharaka, is undoubtedly a 
copy of the leaf-shaped stone arrow-head, of which 
good examples are now coming to light. 
Tue possibility of the existence of some hitherto 
unidentified animals in Central Africa is again raised 
in a communication by Mr. C. W. Hobley, published 
in part 6, vol. iii., of the Journal of the East Africa 
and Uganda Natural History Society. One of them 
is described as possessing ‘thick, reddish-brown hair, 
with a slight streak of white down the hindquarters, 
rather long from hock to foot, rather bigger than a 
hyena, with largish ears.’ Some naturalists are in- 
clined to identify it with the hairy ant-bear, 
Orycteropus; but most of those who have seen it are 
well acquainted with the ant-bear, and it is an almost 
unique phenomenon for an ant-bear to be seen abroad 
in daylight. The natives, again, have tales of a lake 
monster which the Baganda call Lukwata. Europeans 
have seen a strange beast swimming in the Napoleon 
Gulf, which was apparently not a crocodile. An 
American sportsman, E. B. Bronson, saw on the Gori 
River, Lake Victoria, a beast ‘“‘14 to 15 feet long, 
head as big as a lioness but shaped and marked as a 
leopard, two long white fangs sticking down straight 
out of his upper jaw, scaled like an armadillo, back 
broad as a hippo, spotted like a leopard, and a broad, 
fine tail; the imprints of its feet were as large as 
that of a hippo but clawed like a reptile.’’ Another 
monster has been seen by natives ‘‘as large as a 
man, sometimes going on four legs, sometimes on 
two, in general appearance like a huge baboon, and 
very fierce.’’ Naturalists will await with interest the 
discovery of specimens of these strange animals. 
Berore the publication, in The Philippine Journal of 
Science for April last, of Mr. H. O. Beyer’s paper on 
origin myths among the mountain peoples of the 
Philippines, no representative collection of Philippine 
myths had been made. Until recent years it was 
believed that all ancient records written in the 
syllabic alphabets which the Filipinos possessed at 
the time of the Spanish conquest had been lost; but 
two of these alphabets are now found in use by wild 
tribes of Palawan and Mindoro, and ancient manu- 
scripts written in the old Bisaya character have re- 
cently been discovered in a cave in the island of 
Negros. These still await publication. Mr. Beyer’s 
paper is based on oral tradition and gives a large 
collection of interesting legends, including an under- 
ground death-land, a story of the Atlas type, in which 
the world is supported by a post created by the chief 
deity and near which he dwells, and a remarkable 
flood myth current among the Central Ifugaos. It 
may be hoped that Mr. Beyer will continue his 
researches in the new folklore area. 
Mr. T. SueprparD, curator of the Municipal 
Museum, Hull, has issued a fourth edition of his 
catalogue of the collections under his charge. This 
is rendered necessary by the process of rearrange-

ment which followed important additions to the collec- 
tions, and the establishment of the new Wilberforce 
House Museum and the Pickering Museum of 
Fisheries and Shipping, which has done much to re- 
move the pressure on the original buildings. Wilber- 
force House, built for the Lister family, about the 
end of Queen Elizabeth’s reign, a beautiful olduresi- 
dence with numerous relics, was the birthplace of the 
philanthropist, William Wilberforce, born here in 1759, 
and has now become the repository of collections illus- 
trating his life, and of the general history of 
Kingston-upon-Hull. The Pickering Museum is 
largely devoted to collections illustrating the whaling, 
fishing, and shipping industries, the nucleus being 
the specimens collected by a public-spirited citizen, 
Mr. C. Pickering. Hull is to be congratulated on the 
activity displayed by its municipality and residents on 
the establishment of these museums, and the curator, 
Mr. T. Sheppard, on the valuable series of catalogues 
issued’ at a nominal price. 
Dr. W. S. Huntsr’s ‘‘The Delayed Reaction in 
Animals and Children,” affords an interesting con- 
tribution to the ‘Behavior Monograph Series.” A 
release box is employed leading to three different 
compartments, any one of which can be illuminated 
by the experimenter. The compartment which is 
illuminated can be opened and entered by the sub- 
ject, whereas the other compartments are closed. 
Food is obtained by entering the illuminated compart- 
ment. Rats, dogs, raccoons, and children were used 
as subjects. After a clear association had been estab- 
lished between the movements leading to food and the 
light which might appear in any one of the three boxes, 
experiments were begun in which the light was turned 
off before the subject had made the appropriate 
reaction. The research consisted in determining the 
maximal length of this delay-period which is com- 
patible with a correct response, and in ascertaining 
the psychological factors at work permitting of the 
correct response after the delay-period. The atithor 
lays stress on the importance of what he terms 
“sensory thought.” 
THE current number of The Psychological Review 
contains an important paper on association and inhi- 
bition, by Prof. J. F. Shepard and Mr. H. M. Fogel- 
songe, based on the learning of nonsense-syllables. 
In the first series of experiments these were learnt in 
pairs, and subsequently the subject was tested by being 
shown the first syllable of a pair either alone or in 
different combinations. These combinations of first 
syllables were either shown successively or simul- 
taneously. Where two first syllables were shown suc- 
cessively, the second was shown at such an interval 
that the association set up by the former was not . 
already completed in the subject. In a second series 
of experiments, three, instead of two, syllables were 
learnt together, and, in testing, the first two of the 
three syllables were shown simultaneously ; these might 
belong to the same or to different three-syllable groups. 
In other series of experiments two different syllables 
were each separately learnt in conjunction with one 
and the same syllable; the two syllables were subse- 
quently presented successively to the subject when 
tested. The resulting reproduction-times, as measured
