BOTANY. 16-5 



Fleshy fungi ought to be treated like fleshy fruits, 

 that is to say, preserved in spirits. Those whose 

 nature allows them to be dried without much alter- 

 ation, and lichens, ought to be treated like dried 

 fruits ; that is, either put into an herbarium, or 

 dried apart. Ferns, mosses, algae, ought to be 

 dried, and put into an herbarium. If time be 

 wanting, the mosses may all be mingled together, 

 and arranged after their arrival, 



In the present state of science, travellers ought 

 to pay great attention to the collecting small cryp- 

 togamia which spring on living vegetables. The 

 greater part of the spots or excrescences which we 

 see upon leaves, stems, or fruits, are worthy of 

 being gathered and preserved. In this case we 

 ought to gather the leaf charged with the parasite, 

 and a branch in flower of the same tree, to know 

 its specie-. 



Travellers will render an important service to 

 science, by carefully collecting the monstrosities, 

 or permanent accidents of vegetables; such as the 

 natural union of the organs of the same plant, 

 which are generally separate ; the organs which 

 are abortive or altered in their form, their number, 

 or appearance. These cases being out of the ge- 

 neral rule, we cannot prescribe any precise method 

 for their preservation ; we can only observe, that
