The March-April 1971 issue of The A.P.R.O. Bulletin featured my speculative ultrasound piece, shown here. Please note that the page with a color background is not readable when enlarged, but the article's three pages, displayed separately, are -- as is Coral Lorenzen's very kind letter regarding the article prior to its publication. I apologize for working from old faded photocopies of the article because, in keeping with my "excellent" archival system, the actual issue and extras thereof are not available at this time. Sock drawer gremlin struck again, no doubt, expanding its influence amd territory.
