M. Chevalier proved, from documents, that the assertion made on a former
evening, that tobacco was a preservative against cholera, was erroneous.
He stated that twenty-seven mechanics employed in the tobacco
manufactories had died of the disease.--Ibid.

_Prussic Acid a Poison to Vegetables._

The sensitive plant, when exposed to the vapour of prussic acid,
instantly closes its leaves. The same plant, as well as other tender
plants, such as the garden pea and kidney bean, when subject to the
influence of this acid, quickly wither and die, and the laurel-water has
the same effect upon them. It appears also that plants which naturally
contain the acid, such as the cherry-laurel and almond tree, are not
less susceptible of its poisonous action than others. Seeds, steeped for
some time in the acid, lose their power of germination.--Ibid.
