APA. = American Philological Association.
Trans. APA. = Transactions of the APA.—The "Trans. for" 1869 and 1870 form vol. 1. The "Trans. for" 1871 form vol. 2, and so on (1895 = vol. 26).
Proc. APA. = Proceedings of the APA.—These (like the PAOS.) were long issued doubly: first separately, soon after the meeting; and then afterwards, with the Transactions, to which they formed a separately paged supplement, or appendix.
The annual meeting is held in the summer. The Proceedings were sometimes issued before the succeeding New Year's Day and sometimes after. Hence I was sometimes uncertain whether a given Proceedings paper should be entered under the year of the meeting or under the following year.
AJP. = American Journal of Philology. Edited by Basil L. Gildersleeve, Professor of Greek in the Johns Hopkins University. Baltimore. Vol. 1, 1880; etc.
O&LS. = Oriental and linguistic studies: First series and Second series (= Nos. 161 and 181, below, where the contents are given).
For the sake of some foreign scholars, it may be mentioned that The Nation, The Independent, and The Critic are weekly journals, so named, and published in New York City.
