M EXICO. 
This exhibit occupies a large space in the southwest cor- 
ner of the Mining building. The collections are arranged 
well in 2S eases of modern and excellent construction, and on 
separate pedestals. The cases are boxes of iron with glass 
sides, about seven feet wide and fourteen feet long, on feet 
which support them about one foot from the floor. .The 
shelves are of glass about ten feet long and twenty inches 
wide, and two and one-half feet between them. The ores, 
solutions, and products of the Hacienda del Progreso are 
very well displayed, except that the labels are not easily read 
and there is not enough information as to localities. Silver 
and copper from Michoacan de Ocampo. The second case on 
the south side is chiefly filled with clays and building stones. 
The third case is filled with minerals which unfortunately 
rest on their labels so that the latter cannot be read. In 
cases where the labels can be read they are in technical 
Spanish, not intelligible to the ordinary visitor. The fourth 
case shows argentiferous, plumbiferous and ferriferous 
ores from the El Carmen mine. The fifth case contains 
minerals of the heavy and light metals indiscriminately. The 
sixth case contains argentiferous ore from various mines and 
much associated zinc ore. Case No. 7 contains minerals of 
the heavy and light metals. Case No. 8 has a mixed assort- 
ment of minerals and building stones. Case No. 9 contains 
building stones and clays. Case No. 10 has coal from Mich- 
oacan de Ocampo. Case No. 11 contains mixed minerals and 
various grades of ores, but without explanation or descrip- 
tion. There is an elevated map of a district of Tetzicoco, 
Xochimilco and Chalco. Case No. 12 has minerals from 
Pachuca and other localities. This collection is value- 
less because the labels are displaced or covered. 
Case No. 13 has fine " exemplares minerales " of 
galena, malachite, etc., from unknown localities. Case 
No. 14 has galena and other ores from Durango and 
Chiapas. The copper minerals from the latter are especially 
fine; and handsome specimens of Mexican onyx. At the south- 
west end. illustrated topographical and other maps oftheCan- 
delaria mine, the metals produced from its ores and fifteen 
photographs. Case No. 16 has a collection of fossils, miner-
