The first original British work on podiatry, with several illustrations, one hand-colored. Disappointed at being refused a medical degree, Lion, a German Jewish émigré, wrote this book, taking the unusual step of having his name published in both English and Hebrew characters on the title page. “His odd and arrogant writing led to the book being generally derided by the lay and professional press. In fact it is first class and was based completely on his personal experiences and observations. Stripped of its padding it can be seen to be a great improvement on Laforest’s book…. The greatest praise we can give to Lion’s book is to say that every chiropodial writer since has used and borrowed from Upon Spinæ Pedum” (Dagnall, “The history of chiropodial literature,” Journal of the Society of Chiropodists, 20, 1965).
