effacement

[ifās′mənt]
Etymology: Fr, effacer, to erase
the shortening of the vaginal portion of the cervix and thinning of its walls as it is stretched and dilated by the fetus during labor. When the cervix is fully effaced, the constrictive neck of the uterus is obliterated; the cervix is then continuous with the lower uterine segment. The extent of effacement, determined by vaginal examination, is expressed as a percentage of full effacement. See also birth, cervix, dilation, station.

Maclean's work is a constant reference for most, if not all, of the contributors But perhaps the book's own most telling performance is the introduction, unsigned but presumably written by the three editors This self effacement, along with a number of other elements, such as the apposite use of the exclamation mark or the final analysis of Quintilian's poignant tribute to his son, is one of the reasons why, not with standing its declared desire to eulogize the work rather than to purge the pain of the person's passing, the introduction succeeds in convoying at least to this reviewer--a stark sense of grief at Maclean's loss.
