MDCCCXLIX (1849)M. Blanchet has described to the Paris Academy of Sciences, the serious consequences resulting from the process of Whitening Brussels Lace to the persons employed in it. In this process the carbonate of lead is used; and a large portion of it is carried into the atmoshphere, where it is inhaled, and thus produces a serious affection of the intestines. It is also very injurious to the sight and to the hearing. M. Leroy D'Etiolles submitted a new and improved lithotritic instrument.
