scattered through the clay. The Arkansas bauxite occurs, as 

 stated by Prof. Branner, in the Tertiary in the neighborhood of 

 eruptive syenite; it is pisolitic in structure, and varies somewhat 

 widely in color and composition. A series of analyses from the 

 different localities is also given (pp. 152-154). 



5. Mineralogie de la France et ses Colonies, A. Lacroix. 

 Tome premier (Ire partie). 304 pp. 8vo. Paris, 1893. (Baudry 

 et Cie.). — This is a work of much value, giving not only the results 

 of earlier observations, but also the many original observations, 

 especially on the physical side, of the indefatigable author. 

 Minute detail in regard to special mineral localities is much 

 needed, but can be given only in a work like this, which is de- 

 voted to a limited field. 



6. So dalite- syenite from. Montana. — In the paper upon this 

 subject by Lindgren and Melville, in the April number, the 

 table giving the composition of albite and orthoclase near the top 

 of p. 296 is stated incorrectly. It was intended to read as follows: 



Albite. Orthoclase.

V. A Summary of Progress in Mineralogy and Petrography 

 in 1892. — Professor W. S. Baylet's excellent notes, published in 

 the monthly numbers of the American Naturalist, have been 

 collected in pamphlet form, as in former years, and thus give a 

 very convenient summary of the work done in the sciences named 

 through the year. A topical index is added at the end. 



8. A large Australian Meteorite. — It is stated that an enor- 

 mous meteorite, weighing nearly one ton, from western Australia, 

 has been received by Mr. J. R. Gregory, of Charlotte St., Fitzroy 

 square. It is 4 feet 2 inches long by 2 feet 3 inches wide, and 2 

 feet 6 inches thick. — Knowledge, May 1st, 1893. 



III. Botany. 



1. Plants of Orizaba. — We have to note the issue of a posthu- 

 mous work by the late Mr. Seaton, assistant Curator of the Gray 

 Herberium of Harvard University. It comprises descriptions of 

 his collections made during a journey to Mexico by the author. 

 It is published in the Proceedings of the American Academy, 

 Boston. g. L. G. 



2. Die natUrlichen Pflanzenfamilien. — The eighty-fourth in- 

 stallment of this work, to which we have made frequent reference, 

 is the last one at hand. The publisher, Wilhelm Engelmann, of 

 Leipsic, has spared no pains to maintain from the first, a very 

 high standard of typography and illustration. It will be remem- 

 bered that its earliest editor, Eichler, died not long after the 

 work was well in hand. It is now our sad duty to announce that
