Central American antiquities. In all, over 400 

 graves were opened, and showed a typical 

 stone-age culture ; no weapon or cutting tool 

 of bronze, still less of iron, was found. But 

 though the majority of the graves were unin- 

 fluenced by European culture, proof was not 

 wanting that in two cases cemeteries at Orosi 

 and Mercedes were in use after the Europeans 

 had reached the New World. In a grave at 

 Orosi were found some mosaic glass beads, 

 clearly of Venetian origin, and in a grave at 

 Mercedes was a large bead of blue glass. 

 Another valuable contribution to the chronology 

 of the find is afforded by a clay bowl found at 

 Salvador, and bearing Maya hieroglyphs, which 

 probably denote the number of a year according 

 to their chronology, which unfortunately has 

 not yet been connected with that of the Old 

 World. 



Similar explorations were carried out in the 

 Guanacaste peninsula on the Pacific coast, and 

 on the islands in the bay of Nicoya, also at 

 Carrizal on the neighboring mainland. Dr. 

 Hartman then proceeded to Salvador, where for 

 nearly a year he dwelt in one of the largest 

 villages inhabited by the Pipilas, an Aztec 

 tribe, and devoted himself to the study of their 

 manners and customs, and religious ideas and 



made an anthropometric examination of 100 

 Aztec individuals, and took a number of photo- 

 graphs. 



In Guatemala Dr. Hartman visited the Indian 

 tribes, Cakchiquels, Zutujils, Quiches and Xincas, 

 as well as the Huavas on Cape Tehuantepec in 

 southern Mexico. His notes on the language of 

 the last two are of the greatest interest, inas- 

 much as there was previously no material for the 

 classification of their tongue. Here also may 

 be mentioned a test of the so-called nahuatlisms, 

 remains of the ancient Aztec language which 

 have been adopted in the Spanish now spoken 

 in those regions. 



Dr. Hartman returned to Sweden in October, 

 1899, bringing the valuable collections now ex- 

 hibited, which Mr. Sjogren, with great gen- 

 erosity, has handed over to the Ethnographic 

 Museum of the State. 



THE GROWTH OF CITIES. 

 A RECENT census bulletin contains reports on 

 the population of cities having 25,000 inhabi- 

 tants, or more, in 1900. There were 159 of 

 these cities which are placed in four groups ac- 

 cording to their size. The increase in popula- 

 tion from 1880 to 1900 is shown in the following 

 table :

 collection, also a collection of Indian antiquities

The cities of over 1,000,000 should, however, 

 be separated, Chicago having had an increase of 

 54.4 per cent, and Philadelphia of only 23.5.
