is prehaps due in large measure to the hard fate of the party sent 
there from Japan, who lost sixteen of their number during and after 
a violent storm which destroyed their rough houses and al! their 
provisions. 
The island is located northeast of Guam and somewhat north of 
a right line from Guam to the Hawaii islands and it may serve as a 
convenient halfway place for a cable line crossing the Pacific. It 
seems to be a typical coral reef island, but "is not far from a center 
of volcanic activity." It is uninhabited. Its size is about 740 acres. 
Its greatest hight is less than 100 feet and its basis is coral rock. 
Round its shores are six successive beach lines, which denote gradual 
elevation. The surface of the interior is generally quite level. Its 
shape is approximately that of an equilateral triangle with rotmdcd 
points. It is heavily wooded with cocoanut palm, some of the 
trees of which reach the hight of sixty feet, and with a few other 
indigenous species, of which Mr. Biyau reports nine. x. h. w.

Doctor Lorenz describes in th-'s paper, which is preliminary to a 
more extended essay with fuller descriptions and figures, some inter- 
esting forms of Cambrian Algae which he has found in a limestone 
of Schantung in northern China. 
From the rows of pores which he found on the sJender st;ms and 
the dichotomous branching of the tangled branches, etc., he infers that 
these fossils should be referred to the family of Siphonese among the 
Algae. They consist of thickish stems which branch on all sides into 
a tangled mat of fine thread, dichotomously divided 
Dr. Lorenz classifies these forms under the family name Ascomaceae, 
and he distinguishes two genera, cne represented by Ascoma plancro- 
porata n.sp., and MitscJierlichia chinensis. Fuller descriptions of these 
will appear in the magazine of the German Geological Society.
