which may be obtained from coal. The AustraHan Commission pre- 

 sented 6 1 specimens illustrating many important ores of Australia. 

 Many of the specimens are of large size, and the whole accession aggre- 

 gated several hundred pounds in weight. An important feature was 

 a full series of ores and concentrates of lead and zinc from the Broken 

 Hill district. There are also gold ores, tin and copper ores from many 

 localities, and a number of miscellaneous specimens. They are all of 

 excellent quality and will add much to the representation of Australian 

 ores in the Museum. The Bolivian Commission presented 80 specimens 

 consisting chiefly of ores of tin from various mines of Bolivia. A large 

 number of these specimens illustrate ores of remarkable richness. 

 Although Bolivia is one of the world's most important sovirces of tin, 

 the Musetun had previously no representation of its tin ores, so that 

 the accession is especially welcome. Ores of bismuth, molybdenimi 

 and copper were also included in the series received. Among the copper 

 ores, some remarkable arborescent aggregates of native copper are of 

 special interest. The Chinese Commission gave a series of ores number- 

 ing 291 specimens, chiefly from the Province of Honan, China. These 

 include specimens of gold ore, sulphur, silver ore, asbestos, copper ore, 

 stream tin, manganese ore, antimony ore, fluorite, coke, and coal. 

 Specimens of lead, zinc, and iron m^de from these ores were also included. 

 There were also a number of specimens of mineralogical interest, such 

 as two specimens of crystallized cinnabar, a large one of calcite and a 

 nimiber of crystallized smoky quartzes. All of this material is entirely 

 new to the collections, no specimens from this part of China having 

 been previously possessed in the Department. The Commission also 

 presented a model of a large lead mining, milling, and dressing 

 works at Shui kao Shan, Province of Hunan, China. This model is 

 about 13 feet square and represents on a scale of i to 135 the topog- 

 raphy of the region where the lead mines are located and the various 

 buildings, derricks, pits, and tracks by means of which the activities 

 of the mines are carried on. The model has been prepared with care 

 and accuracy and has geographic as well as economic interest. The 

 Greek Commission presented 315 specimens of ores which represent all 

 the important mineral products of Greece except the marbles. They 

 include specimens of zinc, lead, silver, iron, manganese, nickel, copper 

 and chrome ores together with specimens of emery and magnesite. 

 There are also specimens of lead and base bullion made from the ores, 

 and of emery powders, calcined magnesite, magnesite cement and 

 magnesite fire brick. The specimens are of large size and well adapted 

 for museum display. The large blocks of Greek emery are especially 

 satisfactory, as the Museum has hitherto been imable to seoire display
