Footnotes, originally at the bottoms of pages, have been collected and repositioned just before the Index. Page 59: “95 × 1·623 = 154·185” was misprinted as “95 + 1·623 = 154·185” and has been corrected here. The Table of Contents does not list the “Phenomena of Heat” chapter, which begins on page 185; nor the Index, which begins on page 242. Page 95: “adjustible” was printed that way. Page 151: Missing closing quotation mark added after “rapidly evaporate in space.” It may belong elsewhere. Page 221: Missing closing quotation mark not added for phrase beginning “it is a fine invention”. End of the Project Gutenberg EBook of Curiosities of Science, Past and Present, by John Timbs
