Transcriber Note

Although some hyphenation standardization has been employed, other unique spelling and grammatic constructs have been left as in the original printed version. On page 188, the odd fraction of 87 divided by 1 was left as printed In addition to obvious typographical corrections, the following were made:

Page(s) Change
134 “proxility” changed to “prolixity”
135-143 Best judgement used in the table where numbers not clearly
    decipherable in the best images available.
142 BISMUTH, with Antimony starts with 10004 all others start
    with 10000. The “4” was assumed to be a typo and was changed to “10000”.
143 Shows 10,0000. the last “0” assumed typo and removed.
167 Twice shows a fraction of “16/11 of gold”. Although this may be
    a typo for “10/11 of gold” it was left unchanged.
248 “aoules” changed to “aoutes”.
