Letters representing mathematical variables are not marked as italic when this would impair clarity in expressions and equations. The lower and upper limits of definite integrals are indicated by curly brackets, e.g. ∫{0,π}...dθ represents a definite integral with values of θ ranging from 0 to π. The caret character ^ is used in the expression (17/16)^{3/2} to signify raising the fraction 17/16 to the power 3/2. Other exponents are represented using superscripted numerals, e.g. x². Italic text is denoted by _underscores_ and bold text by =equal signs=. Obvious punctuation and spelling errors and inconsistent hyphenation have been repaired. In ambiguous cases, the text has been left as it appears in the original book. End of the Project Gutenberg EBook of The Ether of Space, by Oliver Lodge
