FOOTNOTES:[22]The figures in this plate are magnified 35 diameters.Fig. 1. Lava ofb.c.396. The upper half of the drawing is occupied by a crystal of plagioclastic felspar showing twin lamellation and faint zonal markings, and with numerous irregular dark-brown inclosures of glass, probably containing magnetite dust and matter similar to that of the groundmass of the rock which consists of felspar microliths, granules of olivine, and augite crystals, grains of magnetite, and apparently a little interstitial glass. A crystal of augite is shown near the bottom of the drawing.Fig. 2. Lava ofa.d.1689. On the right hand side part of a plagioclase crystal with inclosures similar to that in the preceding figure. In the centre a small crystal of plagioclase. Groundmass similar to that of Fig. 1, but showing a somewhat definite arrangement of the small felspar crystals, indicative of fluxion.[23]"Mikroskopische Beschaffenheit der Mineralien und Gesteine." Leipzig, 1873; p. 480.[24]"Mikroskopische Physiographie der Massigen Gesteine. Stuttgart, 1877; p. 547.

TRANSCRIBERS NOTES: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.Addition of full-stops where omitted within text outlining chapter highlights; page ix after 'Silvestri', page x after 'Eruptions' and '1408', page xi after 'microscope', page 79 after '812'.Corrected 'ength' to 'length' on page 4.Corrected 't'jncedie' to 't'incedie' on page 12; its leading e has a tilde symbol over it but this has been omitted. Similarly, treblement has been transcribed without a tilde symbol over its leading e.Transcribed 'Guiseppe' as 'Giuseppe' on pages 17 and 144 since this is a more usual form.Added missing endquotes to quotation by Professor Jukes on page 27.Inserted full-stop after '(S.W.)', page 29, to end sentence.Corrected 'f' to 'of' on final line of page 33.Corrected 'of-course' to 'of course', page 42.Corrected 'unusally' to 'unusually', page 44.Corrected 'subsequenly' to 'subsequently', page 59.Corrected 'athough' to 'although', page 64.Numbered list of eruptions repeats item 5, then jumps to seven on page 82. Corrected to numeric order.'In the 1329' corrected to 'In the year 1329', page 85.'the time analcite' corrected to 'the term analcite', page 127.Corrected 'magnitite' to 'magnetite', page 140.Corrected 'Miscroscopic' to 'Microscopic', page 145.
