§ XXVIII. Herbs and Medicinal Plants. (Plantes Potagères et Médicinales.)
Reading edition
I filled a bottle with mint (menthe poivrée) in branches and full of flowers. I stirred it with a stick to make the bottle hold a greater quantity of it. I corked it well, &c. and gave it a slight boiling in the water-bath. It was perfectly preserved.
The same may be done with all plants to be preserved in bunches. The operator will calculate the degree of heat which it will be necessary to give to the several subjects of his experiment.[O]
