generation.—Bathybius.—Panspermia.—The stand-points of
Richter, Ferdinand Cohn, and Lord Kelvin.—The radiation

EXPLANATION OF ABBREVIATIONS, ETC.
The temperatures are stated in degrees centigrade (° C.), either on the
Celsius scale, on which the freezing-point of water is 0°, or on the
absolute scale, whose zero lies 273 degrees below the freezing-point of
water, at -273° C. The equivalent temperatures on the Fahrenheit scale
(freezing-point of water 32° F.) are added in brackets (° F.).
1 metre (m.) = 10 decimetres (dm.) = 100 centimetres (cm.) = 1000
millimetres (mm.) = 3.28 ft.; 1 kilometre (km.) = 1000 metres (m.) =
0.62 miles; 1 mile = 1.6 kilometres (km.).
Light travels in vacuo at the rate of 300,000 km. (nearly 200,000
miles) per second.
