Transcriber's notes:
(1) Numbers following letters (without space) like C2 were originally
printed in subscript. Letter subscripts are preceded by an
underscore, like C_n.
(2) Characters following a carat (^) were printed in superscript.
(3) Side-notes were relocated to function as titles of their respective
paragraphs.
(4) Macrons and breves above letters and dots below letters were not
inserted.
(5) dP stands for the partial-derivative symbol, or curled 'd'.
(6) [oo] stands for the infinity symbol, and [int] for the integral
symbol.
(7) The following typographical errors have been corrected:
ARTICLE EKATERINOSLAV: "Nearly 40,000 persons find occupation in
factories, the most important being iron-works and agricultural
machinery works, though there are also tobacco ... " 'important'
amended from 'imporant'.
ARTICLE ELASTICITY: "The limits of perfect elasticity as regards
change of shape, on the other hand, are very low, if they exist at
all, for glasses and other hard, brittle solids; but a class of
metals including copper, brass, steel, and platinum are very
perfectly elastic as regards distortion, provided that the
distortion is not too great." Missing 'and' after 'steel'.
ARTICLE ELASTICITY: "The parts of the radii vectors within the
sphere ..." 'vectors' amended from 'vectores'.
ARTICLE ELBE: "Its total length is 725 m., of which 190 are in
Bohemia, 77 in the kingdom of Saxony, and 350 in Prussia, the
remaining 108 being in Hamburg and other states of Germany." 'Its'
amended from 'it'.
ARTICLE ELBE: "Finally, in 1870, 1,000,000 thalers were paid to
Mecklenburg and 85,000 thalers to Anhalt, which thereupon abandoned
all claims to levy tolls upon the Elbe shipping, and thus
navigation on the river became at last entirely free. 'Anhalt'
amended from 'Anhal'.
ARTICLE ELBE: "... after driving back at Lobositz the Austrian
forces which were hastening to their assistance; but only nine
months later he lost his reputation for "invincibility" by his
crushing defeat at Kolin ..." 'assistance' amended from
'asistance'.
ARTICLE ELECTRICITY: "De la Rive reviews the subject in his large
Treatise on Electricity and Magnetism, vol. ii. ch. iii. The writer
made a contribution to the discussion in 1874 ..." 'Magnetism'
amended from 'Magnestism'.
ARTICLE ELECTRICITY SUPPLY: "... or by means of overhead wires
within restricted areas, but the limitations proved uneconomical
and the installations were for the most part merged into larger
undertakings sanctioned by parliamentary powers." 'limitations'
amended from 'limitatons'.
ARTICLE ELECTROKINETICS: "A vector can most conveniently be
represented by a symbol such as a + ib, where a stands for any
length of a units measured horizontally and b for a length b units
measured vertically, and the symbol i is a sign of perpendicularity
..." 'symbol' amended from 'smybol'.
ARTICLE ELECTROSCOPE: "The collapse of the gold-leaf is observed
through an aperture in the case by a microscope, and the time taken
by the gold-leaf to fall over a certain distance is proportional to
the ionizing current, that is, to the intensity of the
radioactivity of the substance. 'microscope' amended from
'miscroscope'.
