[Transcriber's Note: An underscore character "_" is used around
text to signify italics in the _original_ text, as illustrated.
It also is used to signify a subscript, used frequently in technical
descriptions. For example _E_{C}_ would have been originally typeset
as a capital E followed by a smaller C subscript, and both would
have been in an italic typeface.]
