it is a problem of no little difficulty for both the ‘‘ perruquier ” 
and the antiquary. But, on the other hand, if it is to be approached 
at all, we do not see that its solution will be successfully attained by a 
refuge to or an introduction of such similies as are taken from Aztec 
paintings, The two nations differ essentially in their mode of delinea- 
tion, and still more in that of moulding, carving, and sculpturing. 
Therefore, in our conception, the true similes for the interpretation of 
the Zapotecan head-dresses ought to be sought by Dr. Seler in the 
cognati tablets, katanes or steles of Palenque and Copan,—

GEOGRAPHY AND TRAVELS. 
The Sierra Madre Expedition.—News has been received from 
the scientific expedition which Dr. Carl I.umholtz is now conducting 
in the wilds of the Sierra Madre and Northern Mexico. 
The expedition started from Bisbee, Arizona, in the early part of 
September, and, entering Mexico, traveled southward through the 
State of Sonora, with the intention of crossing the Sierra in the direc-

westerly direction, covering some 300 miles of territory. From 
Granados the ascent began, and continued steadily until, on December 
2d, the western slopes of the Sierra Madre were reached at Nacory, 
when a northeasterly direction was taken, 
Three mountain ranges had to be scaled, the highest some 9,000 feet

sion upon the minds of the travelers, who took hundreds of photo- 
graphs. _ The weather was very cold. There was snow on the mountain 
tops, and men and beasts suffered severely in many ways. One man, 
a guide, whose health was already impaired, succumbed under the 
strain, and his death was a serious loss to the explorers, as he knew of 
ruined pueblos to which he had pledged himself to lead them. Several
