Throughout Khorassan the air is usually very little charged 
with vapors and its average hygrometrical state varies between 
20 and 80 per cent. At Schakhroud, Mr. Lentz found only 17 
cent of moisture in the atmosphere, and in the desert near 
irman, only 14 per cent.” 
SCHLAGINTWEIT’S ErHNOGRAPHICAL CoLLEcTIONS.—Mr. Joh. 
Ambr. Barth, of Leipsic, has offered for sale a large collection 
of plaster-casts taken from the heads, hands and feet of individ- 
uals in the different castes and tribes of India, and has published 
acarefully prepared catalogue of the series. We make the fol- 
lowing extract from his announcement: 
“Messrs. Hermann, Adolphe and Robert de Schlagintweit, 
the enterprising travelers in India and High-Asia, having, since 
the year 1854, had charge of a scientific mission from the India 
ouse, have been enabled during their travels, in addition to 
their researches jn physical geography and geology, to devote 
much of their time to ethnology. 
“The various countries through which they passed, some of 
which have hitherto been but little explored, and others never 
Teached by Europeans, afforded peculiarly advantageous oppor- 
tunities for pursuing their ethnological researches. : 
“Besides measurements and photographs, they, in collecting 
their materials, made also casts of the features of living persons 
taken in plaster of Paris; 275 casts of faces were thus made, 
and 37 of hands and feet. : : 
. the moulds have been reproduced by galvanoplastic depos- 
1s of copper, which gives without the least contraction the most 
minute irregularities of the skin with great perfection. This 
Series however was found not sufficiently strong, and the 
attempts which have been made to produce the heads in as great 
Perfection as possible, have led to a different method, consisting 
ee strong metallic casts of zinc the basis, coated with a 
Fre Plastic depesit of copper, varied in color according to the 
t degrees of color of the native tribes. To exclude as 
Perfectly as possible the change of the tints by the gradual 
be ation of the copper, a thin stratum of colorless varnish has 
“te most carefully over the heads. ; 
._ +0gether with these casts, measurements of the various pro- 
ons of the skull and the body have been taken, which will
