This little brochure gives in an interesting and practical manner a résumé of the most accredited views on the subject—in which the French writers, however, preponderate. In classification the author follows Vaulair and divides all neuralgias into idiopathic and symptomatic, assigning to the former group much the larger number, though intimating that advancing knowledge will curtail it. Perhaps a frank acknowledgment of inability to explain the true relations of many neuralgic pains would be more desirable than the misleading designation of " idiopathic." Treatment receives many pages and is necessarily polypharmacal. In an appendix of thirty-six pages all the more prominent drugs that are valued in the management of the various neuralgias are considered seriatim.
