Dr. Stiles presented a report on the work of the 
Rockefeller Hookworm Commission, and in this con- 
nection noted the compilation of the nomenclature 
used throughout the world in connection with hook- 
worm disease. He also noted that the name 
Necator africanus given by Looss to a hookworm 
from the chimpanzee was preoccupied and that 
he had written to Looss asking him to change it. 
Dr. Stiles also presented the outline of a sym- 
posium on amebiasis, which is to be part of the 
program at the coming International Congress of 
Hygiene and Demography. 
Mr. Hall presented the following note: 
A Second Case of Multiceps multiceps im the 
Coyote. 
At the meeting of the society in April, 1911, the 
writer presented a note on a case of Multiceps 
multiceps in the coyote, Canis nebracensis. This 
was a case of infection by artificial feeding with 
cenurus, the coyote dying six days later of sep- 
ticemia. Fifty-two heads of M. multiceps were 
recovered from the intestine. I wish to record a 
similar case from a coyote in the same litter, fed 
at the same time. Death occurred 14 days after 
feeding, and in the writer’s absence the post- 
mortem was made by Dr. Graybill, who found 4 
heads of M. multiceps in the intestine. A com- 
parison of these heads with the 52 recovered from 
the first coyote shows that apparently they had 
not developed any more in 14 days than in 6 days. 
In this connection may be mentioned a note pre- 
sented before the society at the meeting in Jan- 
uary, 1911, in which a case was noted where a dog 
fed cenurus 82 days previously was found on 
postmortem to have 5 tapeworms, the largest 
having eggs with undeveloped onchospheres and the 
smallest being less than one half inch in length. 
These data indicate that this worm may at times 
develop very slowly. Leuckart (1886) has noted 
that of three dogs fed Cenurus, one was found to 
have over 100 completely developed tapeworms in 
about ten days; another had only heads of tape- 
worms after three weeks, with bands of segments 
an inch long attached to them in a few cases only, 
while the third failed to develop any tapeworms. 
The remainder of the evening was devoted to a

THE ACADEMY OF SCIENCE OF ST. LOUIS 
THE meeting of the Academy of Science of 
St. Louis was held at the Academy Building, 
Monday, February 19, 1912, at 8 P.M., President 
Engler in the chair. 
Dr. Charles H. Turner presented a paper on 
‘«Eixperimental Study of Color Vision and Pat- 
tern Vision of Bees.’’ The conclusion reached by 
experiments was that bees can distinguish, not 
only between colors, but also between color-pat- 
terns, and that this behavior is of value to them 
in recognizing plants that contain an abundant 
supply of honey. Hence, since bees can distin- 
guish colors and the fine details of color-pattern, 
there is nothing about the visual powers of bees 
that militates against the theory that the colors 
and the color-patterns of flowers are adaptations 
to insect visitors. The bees respond to these col- 
ors, not because they prefer one color to another; 
but, because, under certain conditions the color or 
color-pattern selected has acquired a utilitarian 
meaning—has come to be the sign of something 
worth a response. 
Although Plateau’s conclusions do not harmonize 
with the above statement, yet the actual facts 
observed by him are in perfect accord. 
Dr. H. M. Welpley spoke on ‘‘ Miniature Indian 
Baskets’? and exhibited two specimens made by 
the Pomo Indians which were viewed by means of 
simple microscopes. The foundation of the baskets 
is from the white leaf willow (Salix argyrophylla) 
and is sewed with California sedge (Carex bar- 
bare). The baskets are made in pattern black 
and white, the black being from the root of the 
California sedge. ‘The larger basket is .18 X .10 
inch, with the opening .06 inch across, and 
weighs one fourth grain. The smaller basket is 
.10 X .04 inch, with an opening .04 of an inch 
across, and weighs one twentieth grain. Both 
baskets are woven in the same manner as large 
baskets and carefully patterned. The Pomo In- 
dians, located in northern central California, are 
noted for their basketry, which is unrivaled in 
North America, for workmanship, beauty and 
variety of designs. The women are the weavers, 
but the smaller basket was made by a man who is 
one of the few men weavers among the Pomo 
Indians. GEorGE T. Moor,
