Part 21

In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world.

Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover.

TRANSCRIBER'S NOTES

With the exception of the typographical corrections listed below and some minor changes that may have been made in moving tables or illustrations so that they are rejoined, the text presented is that published in the original printed media. Also, the second instance of t-tests was changed to t-tests as the letter "t" is usually italicized by statisticians.

Emphasis Notation

Text = Italics

$Text$ = Bold

a_{b} = a with subscript b
