1. Analyses of Hocks, Laboratory of the IT. S. Geological 

 Survey, 1880 to 1899 ; F. W. Clarke. Bull. 168, U. S. Geol. 

 Surv., 1900, pp. 30S. This is a new edition of Bulletin 148 of the 

 Survey publications, containing a large number of new analyses, 

 chiefly executed by W. F. Hillebrand and H. N. Stokes. All 

 told, some 1,400 analyses of rocks, clay, soils, etc., are given. The 

 order of the analyses has been changed, the more important con- 

 stituents being given first, as is usual with many petrographers. 

 This makes the analyses much more convenient for use. As 

 before, the arrangement is geographical. The former chapter on 

 rock analysis by Hillebrand is omitted and it is stated that this, 

 in an enlarged form, will soon appear as a separate bulletin. One 

 cannot but be impressed by the enormous amount of painstaking, 

 careful and skillful work represented by these analyses, so com- 

 plete and so detailed. From no other source could such a mass of 

 similar analyses be gathered, and they doubtless represent the 

 most important work done in American chemical geology.

 8. The JBjurbole, Finland, Meteorite. — Portions of this meteor- 

 ite are now on exhibition in the Finland pavilion at the Paris 

 Exposition. The fall took place March 12, 1899. The mass, 

 which had a total weight of about 340 kilos, fell into the Gulf of 

 Finland, making a hole about nine yards in diameter in the ice 

 (which had a thickness of about 28 inches) and penetrating the 

 submarine clay to a depth of six yards. The removal of the mass 

 has been a matter of considerable difficulty and was accomplished 

 only in sections. The portions on exhibition at Paris are the 

 largest secured and weigh 83 and 22 kilos respectively. The 

 interior of the stone is gray with yellowish spots. The exterior 

 is covered with a black crust. Prof. Stanislas Meunier gives in a 

 recent issue of " Le Naturaliste " the results of a detailed study of 

 the meteorite. He describes it as friable in texture and in struc- 

 ture of the variety to which he applies the term oolitic. The 

 mineralogical composition is largely chrysolite and pyroxene, with 

 which are associated grains of nickel-iron, iron sulphide and 

 chromite. Sp. gr. = 3 '54. Chondrites varying in diameter from 

 •5 to 2'5 mm are easily separated. They are of several types, which 

 are fully figured. The most remarkable are those of a fibrous, 

 probably feldspathic, mineral often enclosed in a metallic shell, 

 and those containing porphyritic crystals of augite. The meteor- 

 ite is classed by Meunier as belonging to his Type 38, Montrejite. 

 The stones of Hessle, Aussun, Prairie Dog Creek and Searsmont 

 will be remembered to be other examples of this type.

 Obituary. 

 Professor G. H. F. Ulrich, F.G.S., Director of the School of 

 Mines of Otago University, Dunedin, New Zealand, died on May 

 26, at the age of seventy years. By his active investigations, 

 first in Victoria and later in New Zealand, he contributed much 

 to the knowledge of the Mineralogy and Geology of those 

 countries.
