gratitude my great indebtedness to Professor 
Francis Tangl, director of the Royal Hun- 
garian Institute for Animal Physiology. The 
unusual generosity with which he placed at my 
disposal equipment and experience has alone 
made possible results which otherwise would 
have been quite beyond my reach.

THE AMERIGAN ASSOCIATION FOR THE 
ADVANCEMENT OF SCIENCE 
SECTION F 
MEETINGS of Section F were held on Wednesday, 
December 27, the forenoon session for the reading 
of papers and the afternoon in joint session with 
the American Psychological Association. The fol- 
lowing officers of the section were elected: 
Vice-president and Chairman for next meeting— 
Professor William A. Locy. 
Member of Council—Professor Edwin Linton. 
Member of Sectional Committee for five years— 
Professor A. M. Reese. : 
Member of General Committee—Professor T. W. 
Galloway. 
The following abstracts of papers have been 
received by the secretary of the section; 
REESE, ALBERT M.: Effect of Narcotics wpon the 
Development of Hen’s Egg. 
The paper is a preliminary account of the 
effect of certain reagents (alcohol, ether, chloro- 
form, chlorotone and magnesium chloride) upon 
the development of the hen’s egg. Alcohol was 
fatal in’ about 75 per cent. of the experiments; 
ether in about 35 per cent.; chloroform, chlorotone 
and magnesium chloride were almost universally 
fatal, though the fatalities in the last two cases 
were probably largely due to faulty technic. 
LINTON, EDWIN: (1) The Adult Stage of Dermo- 
cystis ctenolabri Stafford. (2) Trematode Spo- 
rocysts im an Annelid. (No abstracts of these 
papers received.) 
RowRER, C. W. G.: Observations on the Chestnut- 
worm. 
The chestnut-worm, or grub, is the larval stage 
of Balaninus caryatrypes, one of the Curculionide 
or nut-weevils, The ‘‘worm’’ winters in the earth, 
and issues forth in the spring as a small snout- 
beetle or weevil. A peck of chestnuts may con-

tain as many as 5,838 worms. One chestnut may 
contain four or even more. The female, in laying 
eggs, first bores a hole with her snout through 
the growing chestnut-burr and into the nut. She 
then drops an egg into this hole, and pushes it to 
the bottom of the hole with her snout. 
REED, H. D.: The Occurrence of Dermal Poison 
Glands in the Nematognathi. (No abstract re- 
ceived. ) 
SmirH, Hue M:.: Notice of a Remarkable New 
Family of Pediculate Fishes. 
Among the fishes collected by the Albatross 
during the 1907-1910 expedition to the Philippine 
Islands is a deep-water pediculate from the coast 
of Celebes, which becomes the type of a new spe- 
cies, genus and family. 
RoGers, Burton R.: A New Method of Preserving 
Anatomical Dissecting Material of Large Ant- 
mals. (No abstract received.) 
SmitH, MippLETON: The Bowhead. 
Description of the whale; of the primitive im- 
plements used in its capture; of the method of 
killing and ‘‘cutting in’’ as practised by the 
Eskimo; and of the uses of its products. 
CuarK, AUSTIN H.: A Biological Contribution to 
the Paleogeography of Australia. 
The old continent of Australia included the 
present Australia, with New Guinea and the Aru 
Islands to the north and Tasmania to the south. 
Timor, Timorlaut, the Ki Islands, Ceram, Gilolo 
and the islands further west, the islands north of 
New Guinea, New Britain, New Caledonia, Nor- 
folk Island, New Zealand and the islands further 
north and east have no relationship whatever with 
Australia, but form part of more or less: marked 
subdivisions of the East Indian region. 
The Australian coast line has subsided since the 
maturity of the true Australian crinoid fauna; 
this subsidence has been least on the southeast 
coast, the degree gradually increasing toward the 
west and with slightly greater rapidity toward the 
north; on the west coast there is a similar increase 
in the degree of submergence from the south to 
the north. The Australian crinoid fauna of to-day 
is in, the midst of. one of those faunal changes 
called by Cuvier a ‘‘cataclysm.’’ 
JOHNSON, M. E., and Torrry, H. B.: Control of 
Color Differentiation in Frog Tadpoles. 
Experiments have shown that the amount of 
melanin developed in.the skin of frog tadpoles 
‘varies with the kind rather than with the quantity 
of food. Among tadpoles growing at the same
