Reading edition
Dr. Bostock states that the best proportions for this coating are, one part of common pipe clay, to three parts of fine sand; which are to be well kneeded together, and reduced to such a state of tenacity, that the lute will readily adhere to the tube, and its different parts unite without forming a visible seam. “Observations on the different methods recommended for detecting minute portions of Arsenic, by J. Bostock, M.D.” Read before the Liverpool Medical Society, and published in the Edinburgh Med. and Surg. Journ. April, 1809.
