In an article in the Neues Jahrbuch Bauer’ gives a German trans: 
scription of his article’ on the rocks associated with the jadeite of 
Turmaw, Burmah. 
‘Schroeder vander Kolk" describes ‘peelly a series of rocks collected 
by Martin in the Moluccas. In the southern part of Amboina the 
rocks are mainly granite and peridotite, while in the larger northern 
part they consist of modern volcanics, as they do also on the other 
islands studied. These rocks are principally dacites and liparites, but 
on one island andesites occur. oth the dacites and the granite con- 
tain cordierite. The dacites are pyroxene and biotite varieties. The 
andesites are pyroxenic; mica schists, breccias and limestones occur 
also on the islands. The residue left after treatment of the limestone 
with acid contains quartz, sanidine, plagioclase, biotite, amphibole, 
orthorhombic pyroxene, hematite, garnet, cordierite, sillimanite and 
pleonost. 
BOTANY.’ 
The Evolution of a Botanical Journal.’—In November of the 
present year the Botanical Gazette reaches its majority, by attaining 
theage of twenty-one years. It first appeared in November, 1875 under 
the name of the Botanical Bulletin, and consisted of four pages of short 
notes. It was edited by John M. Coulter, then professor of Natural . 
Sciences in Hanover College (Hanover, Indiana). In his introductory 
_ note the editor stated that the object of the new journal was “to afford 
a convenient and rapid means of communication among botanists. The 
context shows that it was started as a distinctly western journal, in- 
tended to supplement the work of eastern botanical publications. 
The first volume included notes by the editor, and Thomas C. Porter, 
Samuel Lockwood, G. C. Broadhead, M. S. Coulter, Mary E. Pulsifer 
Anes, J. T. Rothrock, H. C. Beardslee, Coe F. Austin, George Vasey, 
Alphonso Wood, Isaac Martindale, Elihu Hall, E. A. Rau, and others 
who have long since diappeared from the. botanical field. With the
