Revue d'histoire de la pharmacie - Année 1972 - Volume 60 - Numéro 212 - Pages 23-28Ancient apothecary weights are scarce in french museums and private collections. Misled by some coïncidences, a french metrologist wrote that a set of weights, property of the Toulouse Museum, was representing the medicinal pound used in France before the metric decimal system. The present author gives to these little monuments their true signification : weights for determine the specific weight of cereals. This method was introduced by the Dutch, in the 17th century. It consists of fulfilling a recipient whose volume is carefully calculated, and to weigh it. The weights are marked in such a fashion that, on reading the sum of their marks, one find exactly the weight of the unit of capacity : pounds per bushel, in Holland, kilogrammes per hectolitre in France. 6 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
