Transcriber's Notes
Obvious typographical errors have been silently corrected. Variations in hyphenation have been standardised but all other spelling and punctuation remains unchanged.
The following corrections have been made:
From
[III.] 3Ca(PO3)2 + 10C = 10CO + Ca3(PO4)2 = P2
to
III. 3Ca(PO3)2 + 10C = 10CO + Ca3(PO4)2 + P4
From [3Ca](PO3)2 + 5Ca2 = Ca3(PO4)2 + 10CO + 4P.
to
3Ca(PO3)2 + 10C = Ca3(PO4)2 + 10CO + 4P.
