Prof. Marsh describes the lar~"st
land animal yet known to have exit
ed on this globe. It's name is At'4ntt-
SGt1'us inlDl03US. The thigh bone 81
this animal is over eight feet long,
with thickness at one end Of TWEEN
ty-fvc inches. A comparison OF this
bone with the femur Of the crocodile
would indicate that the fossil sauian,
il Of similar proportions, must have
been one hundred and fifteen feet long.
That the reptile was one hundred aHI
fifteen feet long when alive IS most

Another electric lamp has been de-

number Of square carbon rods placed
radially upon disk of wood or ineJ;ti,
so that the inner ends of the carbon
rods form complete circle. There is
circular opening in the wooden
disk through which the light is seen
from beneath. The carbons are forced

Mr. H. N. Mosely, in recent lee
ture, maintained that at comparatively
small depths in the sea it is almost
certainly entirely dark so far as sum
light is concerned. Prof. Forel found
that in the Lake of Geneva, even at a
depth of only thirty tathoms, photo
graphic paper was entirely Enacted
upon after protracted exposure. We
can hardly believe, Mr.. Mosely says,
that the red, green OF yellow rays can
penetrate sea-Water much further
