Dear All, As those who attended last summer's meeting of the North American Sundial Society know, I have done some research on the Margaret Mayall and R. Newton Mayall, authors of the well-known, Sundials: How To Know, Use, and Make Them, and their connections to sundials presently in Harvard's Collection of Historical Scientific Instruments. My research paper has not yet been published.
One of the manuscripts I have used was a typescript catalog of the Ernst Collection by the Mr. and Mrs. Mayall. The document is held at the Harvard College Observatory. It was recently digitized and is now available online. You can find it here: The Harold C. Ernst Collection of Portable Sundials Mayall, R. Newton Mayall, Margaret W. http://zenodo.org/record/8326 Best wishes, Sara Sara J. Schechner, Ph.D. David P.
