«TRANSCRIBER’S NOTE»

Original spelling and grammar are generally retained, with some exceptions noted below. Original page numbers look like this: {36}. Original italics look like this. Scanned page images of the original book are available from archive.org, search for henleystwentieth00hiscrich. Illustrations have been moved from within paragraphs to nearby locations between paragraphs. The transcriber produced the cover image, and hereby places it in the public domain. Large curly brackets “{}” intended to combine information over more than one line of text have been removed, replaced by appropriate text to retain the original meaning. Subscripts are in this simple text edition indicated by the form “〈..〉”, as in “C〈12〉H〈22〉O〈11〉”. Original small caps have been converted to uppercase.
