Lettre écrite à Monsieur le Chevalier Guillaume de Waidegrave …contenant une dissertation physique sur la continuité de plusieurs os, à l’occasion d’une fabrique surprenante d’un tronc de squelette humain, où les vertebres, les côtes, l’os sacrum, & les os des iles, qui naturellement sont distincts & separés, ne font qu’un seul os continu & inseparable.

First description of ankylosing spondylitis. The British Museum copy of the title page of this work has been mutilated, apparently deliberately, in two places; the author’s surname may originally have appeared as “O’Connor”, and the last part of the date has been cut away and appears as MDCXCI; other authorities give 1693 as date. The copy presented to the Royal Society of London is also mutilated to read “Connor”. Connor graduated MD in Reims in 1693. Partial translation by Baruch S. and Jean L. Blumberg, "Bernard Connor (1666-1698) and his contribution to the pathology of ankylosing spondylitis," J. Hist. Med., 1958, 13, 349-66.
