dreams of the visualizing and symbolizing ty pes of individuals. Whether 
good visualizers are better dreamers, or whether their dreams are merely 
of a different character from those of symbolizers, remains to be seen. 
But certainly the question is well worth investigating. So far as I 
know, no attempt has yet been made to gather data bearing on this point.

Courtship of Grasshoppers.'’—Prof. E. B. Poulton has observed 
this process in two different genera of Acridiidæ. In the case of Pezo- 
tettiz pedestris the sombre brown male quietly awaits, without audi- 
ble stridulation, the appearance of a female, and jumps upon her 
unawares. At first she tries to escape, but after a little struggle sub- 
mits. Before pairing the male nibbles the female gently, and while 
holding her keeps moving his short legs up and down. This latter 
process Prof. Poulton regards as a vestige of true stridulation, and that 
it may still be of use in influencing the female in some way. 
In the case of Gomphocerus sibiricus the process is much more cere- 
monious, the males stretching out their four palpi, stridulating, and 
even patting the female. Apparently the habits are influenced by 
temperature, for certain phases of courtship could be studied most satis- 
factorily when the insects were first aroused to activity.—F. C. K 
ANTHROPOLOGY.’ 
Recent Pile Structures made by Seminole Indians in East 
Florida.—Mr. Henry G. Bryant, Secretary of the Geographical So- 
ciety of Philadelphia, informs me that he saw, in the latter part of 
March, 1896, several pile-built structures made by modern Seminole 
Indians rising above the water of a salt estuary of the New River in 
Dade Co., Florida. He, in company with Dr. Murray Jordan, had 
visited the Seminole settlement called Big City, situated on the east- 
ern side of the Everglades, within reach of the tide-water of New River, 
and above the site of old Fort Lauderdale, a region now made access- 
ible by railroad from Lake Worth to Miami. : 
Ascending the river in a small steamboat for some eight or ten miles 
above Fort Lauderdale, Mr. Bryant, with a local guide, had pro- 
ceeded in a flat-bottomed boat over a submerged meadow-like country 
to Big City, which he found to consist of six or eight rectangnlar huts
