To Duchenne de Boulogne we owe the description of "progressive locomotor ataxia" or tabes dorsalis, of syphilitic origin,           by lack ol motor coordination and usually accompanied by abolition of the reflexes and deep sensibility: see, "De I'ataxie locomolrice progressive," republished in De I'ataxie locomotrice progressive (Paris: Rignoux, 1859).
