A collection of fruits is the indispensable complement of the herbarium. To render work easier it is as well to place it as near the latter as possible.

After well washing the freshly-gathered fruits in order to free them from foreign matter (care being taken during the operation not to rub them in such a way as to deprive them of certain important characters, such as colour, villosity, etc), they are put into jars containing alcohol and water. These fruits should carry a securely fastened parchment label, on which is written the number of the memorandum book. The lead pencil has the advantage over ink that the writing does not become effaced in alcohol; yet for greater safety, it is preferable* to form the numbers with a punch. A series of figures does not cost very dear, by reason of the security offered by the tickets that it permits of making.

If a person is travelling, and wishes to ship the fruits, he will -merely have to close the jars tightly with good corks, covered with a thick layer of bottle wax. Sealing wax dissolves in alcohol, and it is therefore very important to have corks that adjust themselves perfectly to the vessel if one wishes the corking not to be defective. The jars should be carefully packed to prevent breakage. They should be accompanied with a catalogue bearing notes from the memorandum book opposite the numbers.

When it is desired to arrange the fruits, it is often necessary to change the alcohol, which, in certain cases, rapidly darkens. The liquid should be changed several times, until it remains of sufficient limpidity.

A large number of systems have been devised for closing the jars. A cork stopper, when of good quality, has the advantage of being easy to insert and extract, and that is to be taken into consideration if it is necessary to examine the specimens often. At the museum are used jars with a lip, which are covered with glass discs, held by glaziers' putty. After the latter is dry, a piece of bladder is glued to the disc, and its edges are tied around the neck with a string. Finally, the whole is covered with thin tin foil. There is nothing further to do but to put a label on the jar bearing the name of the fruit, its origin, and the name of the collector. As the same number is carried by the specimen in the herbarium and the jar containing the fruit, it permits of easily bringing together these parts when it is desired to study them.

Dry fruits are simply put into glazed boxes or into bags or jars.

The classification of the collection of fruits should be done in the same order as that of the herbarium.
