Inconsistencies in spelling (e.g., D'Arboval/D'Arborval) and hyphenation (e.g., postmortem/post-mortem) have been resolved in all cases where it was possible to divine the author's intent with a reasonable degree of certainty. The occasional error which could not be resolved was marked [sic]. Italicized letters and words are enclosed by _underscores_. Subscripts are represented by an underscore and curly braces: _{2} (for example, SiO_{2}). Ligatures which cannot be reproduced in the Latin-1 character set are enclosed in [brackets] (for example, C[oe]nurus). * * * * * [Extract from "An act making appropriations for the Department of Agriculture for the fiscal year ending June 30, 1924, and for other purposes," approved February 26, 1923.
