Prof. Ehrenberg on Microscopic Life 
II. Oceanic materials from M. Schayer. 
M. Schayer, of Berlin, who for fifteen years was superintendent 
of English slieep-folds at Woolnorth in Van Diemen’s Land, 
has, in answer to a request sent to him in the year 1842 by the 
author, collected materials unquestionably rich in microscopic 
animals; he also collected water taken from the ocean in different 
regions on his return in 1843, and brought with him to Berlin 
four bottles holding from a quarter to half a pint. The author 
had wished that water had been drawn up at a distance from the 
coast in accurately known places, in order to become acquainted 
in some measure with the usual amount of microscopic life of the 
ocean. 
The four well-preserved sealed bottles which have arrived in 
Berlin were shown to the Academy by the author, and the water 
is still quite clear and transparent, having only a few flakes at 
the bottom, which render it turbid when shaken, but soon sub¬ 
side again to the bottom, and the former transparency is restored. 
When opened, a slight but yet evident trace of sulphuretted 
hydrogen was perceptible. 
The microscopic investigation has given the following results : 
1. Water from the south of Cape Horn on the high sea under 
57° S. lat., 70° W. long., contained— 
SILICEOUS POLYGASTRICA. 
1. Fragilaria yranulata . 3. Lithostylidium Serra. 
2. Hemiaulus obtusus. 
2. Water from the region of the Brazilian coast, near Rio de 
Janeiro, on the high sea, in 23° S. lat., 28° W. long.
