Transcriber's notes:

(1) Numbers following letters (without space) like C2 were originally
printed in subscript. When letters are subscripted, they are
preceded by an underscore, like C_n.

(2) Characters following a carat (^) were originally printed in
superscript.

(3) Letters topped by Macron are represented as [=x].

(4) [oo] stands for infinity; [int] for integral; [alpha], [beta], etc.
for greek letters.

(5) The following typographical errors have been corrected:

Page 871: "an equation which is very useful, because it enables us,
if we know the distribution." 'because' amended from 'becaus'.

Page 890: "The colour of the luminosity due to positive rays is not
in general the same as that due to anode rays." 'positive' amended
from 'postive'.

Page 890: "Anode Rays.--Gehrcke and Reichenhein (Ann. der Phys. 25,
p. 861) have found that when the anode consists of a mixture of
sodium and lithium chloride." 'mixture' amended from 'mixure'.

resistivity, may be defined as a quality of a substance in virt
