microbe, Kirstein proposes the following procedure: The sediment 
is transferred to a cup-shaped glass, well stirred with a glass rod 
and filtered ; then the residue is poured on a watch glass, some of 
the matter crushed between two slides, and treated in accordance 
with Ehrlich’s method. The result of this procedure was the find- 
ing of the bacilli in each of the preparations thus obtained.—The- 
rapeutic Gazette. 
GicANnTIc SEAWEEDS.—Some of the gigantic seaweeds have 
stems which exceed in length any of which terra firma can boast. 
Recently the ship “ Clever,” commanded by Capt. John Stone, ar- 
rived at Montevideo with a portion of a seaweed which had been 
picked up in the Atlantic near the equator. The sailors perceived 
an object floating on the surface some distance from the ship, and, 
manning a boat, they rowed to it, and ascertained that it was an 
alga of enormous size. On measuring it, it was found to have a 
length upward of fifteen hundred ‘feet. It has been identified by 
botanists as Macroceptis pyrifera. 
S. Barrons, writing to the English Mechanic, says that he finds 
that the price charged by the English workmen for the delicate and 
accurate brass work of a microscope is generally equal to the en- 
tire charge for the complete instrument abroad. If, however, the 
purchaser be contented to pay the tip-top prices of the best Eng- 
lish makers, he may be sure of obtaining an instrument which will 
fear no rival. The disparity in the prices of labor and food in 
England and the Continent accounts for the difference in the cost 
of a good of microscope.
