ACADEMY OF Sctence, St. Louis. — April 3d. Professor Potter, 
Chairman of the Committee on Mound Exploration, made a partial re- 
port, as follows: The committee have examined and made a survey of 
five groups of mounds. Two hundred specimens of pottery have been 
obtained, of which one hundred and twenty-six are quite perfect, the 
remaining specimens being in a fair condition, and may be wholly or in 
part restored. The collection also embraces the skulls of twenty indi- 
Viduals, of which number one is complete, seven nearly so, the remain- 
ing twelve being in fragments of sufficient size to be of value. They 
have also obtained the leg and arm bones, and in some cases the verte-

collection of pottery taken from the burial grounds of an ancient tribe of 
eruvians, The graves from which the specimens were taken were in 
‘Very dry drift sand near the sea-beach. The graves are supposed to 
belong to a tribe that was conquered by the Incas fifty or sixty years 
before the advent of Pizarro in Peru. Many bones were found, being 
Preserved by the perfect dryness of the sand in which they were buried. 
The greater portion of these relics were found along the line of the 
Chimbote and Huaraz Railroad, latitude 7° S., and with few exceptions 
Yy represent what are supposed to have been drinking-vessels. In 
several of the specimens the handle, which is hollow, arches over the 
top of the vessel, the two branches of the tube uniting in a single ver- 
tical tube of several inches in length. The ornamentation, both in form 
and color, was in many cases very striking and expressive. A small
