Owing to the great amount Of decom.
posed vegetable matter contained in
Brazilian waters, which causes rapid
deterioration Of thin steel, the hull
Of the new dispatch boat Guanabara,
built for the Brazilian Government, is
constructed entirely Of bronze. Against
this metal says Popular Mechanics, the
corrosive action of the Brazilian waters
has no effect, and, although more cost
~, both in material and construction,
the vessel is much lighter than IL built
Of steel or wood. The propeller shaft
ing and propeller are also Of bronze.
The brownish spots which appear in
old books are really due to the ravages
Of bacteria. says Popular Mechanics.
The tiny destroyer is especially fond Of
starchy material and its propagation is
promoted by damp. 1t has been we'll
understood that damp produced discol-
Grafton and decay, but the share Of the
microbe in the operation has not hith-
erto been suspected. Tiny fungus or
mold is responsible for gray and black
marks upon old papers. In spotting
the surface the fungus helps to break
Of its destruction.
R. Lydekker the English naturalist
calls attention to the observations Of
r. I. Pocock on the significance of the
close relationship of lions, tigers ant
leopards On lion cubs the pattern o
the markings is intermediate in char
acter between the stripes of the tige
' and the rosettes Of the leopard, but in
4 clines more toward the former. Eas
t African lions retain more or less dis
+ tinct traces Of these early marking
even when they reach maturity. A dis
|, tinct tiger-like feature Of the lion Gu
! is a white patch over the eye, whic
d disappears in the adult. Puma cub
a show a pattern quite unlike that of tn
e lion, tiger, leopard and jaguar.
At the recent meeting Of the Amer
q can Association for the Advancement
}: Of Science, in Chicago, attention wa
u called to the interesting fact that tn
work on the Panama Canal Is changin
biological conditions in Panama, an
that its completion will enable tn
~ fresh-water faunm Of the Atlantic al
- Pacific slopes to intermingle, Undoub
- eddy many marine animals will pal
from one ocean to the other. Thus
- permanent change Of conditions will
y, brought about, which may or may n
possess much practical Importance, b
it's scientific interest Is very great.
- view of these facts the association r
-. solved to urge upon Congrcss the nece
y, sity Of an immediate biological surv'
q Of the Panama Canal zone.
Ia The report that the Gulf Stream nc
Iis runs with greater speed than former
nd and its influence ON the time requir
va for the crossing Of the Atlantic, fl
~. nishes the theme for an article by
,o Brennecke in the German magaZil
n Umshau. DR.. Brennecke analyses
climatic and geographical reasons
the existence and continuance Of
Gulf Stream, and points out how t
raj change in the wind currents and
he density Of the atmosphere all affect
B. life and power Of the famous cure
Zip This is chiefly dependent. he points o
on the location and areas Of high a
low pressure over the sea. A series
Fl carefully made reports over a 10
period Of time by the German Mari
lot Observatorium seems to indicate IL
the Gulf Stream now moves more r,
tn Idly than formerly.
