594 THE AMERICAN NATURALIST. [Vor. XXXIV. 
Mr. W. C. Mills, curator of the museum of the Ohio State Arche- 
ological and Historical Society, has prepared a report of the field 
work of the society for the year ending May 31, 1898, that has been 
published in Vol. VIII of the Annual Publications of the Society. 
The work consisted in the exploration of mounds and the addition 
of new data to the state archeological map. The explorations seem 
to have revealed little that is new, though the discovery of post 
molds in a mound in Knox County is worthy of note. These molds 
were in the form of a square twenty-seven feet on each side. In the 
center of the enclosure was a fire pit of yellow clay six feet in diame- 
ter. In another mound five headless skeletons were found promis- 
cuously heaped together. This recalls the discovery made at the 
Turner Mounds, a number of years ago, of sixteen skulls that had 
been buried together. 
In the Bulletin of the American Museum of Natural History, Vol. 
XIII, pp. 69-86, appears an article by Mr. A. L. Kroeber upon the 
“ Symbolism of the Arapaho Indians." It is very concisely written, 
and illustrated with 138 figures representing the symbols most com- 
monly employed. These range from a straight line (Fig. 24) to 
a silhouette of the human figure (Fig. 124). Mr. Kroeber con- 
cludes that the symbolic tendency prevails over the decorative in 
Arapaho art. 
In the American Anthropologist (N. S.), Vol. II, No. 2, is published 
a paper by Dr. J. R. Swanton upon the ** Morphology of the Chinook 
Verb " that should be of interest and value to students of the science 
of linguistics. It is an exhaustive study of the verb, prefaced by a 
general account of the other parts of speech in the Chinook language. 
This thesis was accepted at Harvard University as fulfilling the require- 
ments for the degree of Doctor of Philosophy. 
ZOOLOGY. 
A Zoégeographic Scheme for the Mid-Pacific.! — Some time ago 
(American Naturalist, No. 396, p. 975, December, 1899) we called 
attention to C. Hedley’s views on the former existence of an antarctic 
continent ; now, a recent paper has come into our hands on a sub- 
ject that is intimately connected with the question of the origin of 
the faunas of the Central Pacific Islands, Australia, and New Zealand.
