    Patrick Drummond, A Master Extra, in Chancery. Silvestri s Improvements in Preserving Animal and Vegetable-Substances, into a convenient vessel, either of glass or earthenware, and capable of receiv¬ ing the leaf, flower, or grass I wish to preserve from decay, a layer of the above described preparation; on that bed I lay the leaf, flower, or grass, which I cover softly and with care with a bed of the said preparation, introducing at the same time, with a spatula or other convenient instrument, into the internal 5 parts of the plant as much as possible of the said preparation. I place after¬ wards the vessel upon some sand lightly heated to help the complete dissua- tion, taking care to keep the sand in the same degree of temperature during five or six days, a time quite sufficient to perform the operation. I take from the vessel the plant, shake it lightly, and then, with small iron pinchers, or any lo such like instrument, I replace in their natural position any part of the plant which the operation or the laying might have put out of order. And having now described the nature of my said Invention, and the manner of carrying the same into effect, I declare that what I claim as my Invention is the introduction into the cavities of organic matter hard substances by means 15 of liquids, and the mode in which the same is to be introduced. 2nd.
