The Monthly Review 53: 506 (Dec 1775)

X. The lovers of agriculture, and rural improvement, will find in the following work several things worthy of their attention—Examen de la Houillé, considerée comme engrais des terres, i. e. An Inquiry into the Properties of Charcoal, considered as Manure for fattening Land, by Mr. Raulin, M. D. King's Councilor and Physician, Royal Censor, F. R. S. and member of many academies. The ingenious Naturalist proposes considering; the effects of charcoal (which in many places of France, and the Low Countries, has been substituted as manure, in the place of turf-ashes) on vegetable ground, on the vegetables it produces, and upon the animals that feed upon its productions. These effects he considers as pernicious, or, at least, liable to suspicion; and this he concludes from the vitriolic, ferruginous, arsenical, and inflammable principles of the charcoal, and more especially from the vitriolic acid from which no kind of charcoal is exempt. For the detail of his arguments and illustrations, the Reader must have recourse to the work itself, which is composed with modesty, and discovers in the Author a rich fund of observation and experience.
