Page Correction --------------------------------------------------------------------- - Some arcane spellings retained where verified as correct for the time of publication or quote, such as 'musquitoes', 'plaintain', 'mettals', 'felspar', etc. - Italian quotations sometimes include phrases such as "sull' Etna" or "dell' Asia". There should be no space after the apostrophes but spaces are often present. This may have been done to better space the text during justification. Such errors have not been corrected. - The document is inconsistent in the use of commas where quoting numbers of over 1,000; sometimes they are used and sometimes they are not used. These inconsistencies remain. ix Added '.' at end of 'Silvestri' in text block to maintain style of other entries. x Added '.' at end of 'Eruptions' in text block to maintain style of other entries. x Added '.' after '1408' in text block to maintain style of other entries. xi Added '.' after 'microscope' in text block to maintain style of other entries. 4 Corrected 'ength' to 'length'. 12 Corrected 't'jncedie' to 't'incedie'.
