His writing on the subject is considered a an authoritative set of rules.There are six editions from the presses of Zolkiews, four of which are found in the Gross Family Collection, bound in one volume. Weil's composition is often printed with commentaries. In this book the commentary is named Imri Tov. In this edition is a full page woodcut with an illustration of the lungs.
