At last Rosenbusch’ has replied to Michel Levy’s criticism of his 
classification of massive rocks. In this reply the author first corrects 
some misstatements made in Levy’s brochure, and then discusses the 
questions of priority which the French savant raises. After effect- 
ually disposing of these points Rosenbusch gives the reasons that led 
him to suggest the separation of massive rocks into the three classes, 
the plutonic, the volcanic, and the dyke rocks, and states that the 
recent work of all petrographers has strengthened his determination 
to hold to this classification. 
The granite, porphyry, schist and clastic rock boulders occurring in 
the various conglomerates aud breccias of the “ Flysch ” in Switzer- 
land have been thoroughly studied by Sarasin,” who recognizes among 
them many that are identical in substance with rocks in the Southern 
Alps. This fact leads him to suggest that the middle Alps were not 
elevated to anything like their present height at the time when the 
conglomerates and breccias were formed, but that there was then an 
unimpeded course from the Southern Alps to the northern side of the 
Northern Alpine ranges. 
In an article entitled The Geology of the Massive Rocks of the 
Island of Cyprus, Bergeat” describes with very little detail diabase, 
gabbro, wehrlite, serpentine, andesite, liparite, trachyte, and andesitic 
and liparitic tufas, all of which occur in some quantity on the Island. 
All are very much altered. 
In a block that fell from the walls of the Legbachthal, Oberpinz- 
gau, in the central Alps, Weinschenk” found a small dyke of much 
altered kersantite. On the contact of the dyke with the intruded 
biotite feldspar schist the latter is changed to an aggregate of epidote, 
quartz, feldspar and muscovite. 
ibsch” describes from Southern Paraguay a sandstone, a quartz 
porphyry and a nepheline-basalt. 
Josephinite, a New Nickel-Iron Alloy.—Josephinite™ occurs 
as magnetic pebbles in the placer gravel of a stream in Josephine and 
Jackson Counties, Oregon. The pebbles consist of a greenish-black 
siliceous substance intermingled with grayish-white areas of the alloy.
