and does not freeze but with a cold below O of Fahrenheit. It is what is 

 called a drying oil ; that is, after being exposed to the open air, and absorbing 

 oxygen, it remains transparent, instead of becoming opaque, like what are 

 called fat oils. Linseed, in common with other vegetable mucilages, affords 

 but little nourishment ; and, when used as a principal article of diet, it 

 relaxes the organs of digestion, and produces a viscid slimy mucus, and a 

 morbid acid in the primae vise. A table-spoonful of the oil is an excellent 

 corrector of habitual costiveness, and one of the most useful poultices is 

 made from linseed-meal. 



iinum catharticum. An indigenous annual, which, as its specific name 

 implies, may be used as a purgative. 



Cephaelis (kephale, a head ; flowers) ipecacuanha (ipe, an aboriginal word 

 in Peru for root, cacuan, an aboriginal distinction for that root), Ipecacuan. 

 {fig- 56.) . A perennial found in most woods 

 near Rio Janeiro and other provinces of Brazil, 

 and one of the most valuable emetics. It is 

 given in a great variety of forms ; one of the 

 most commodious is emetine, or concentrated 

 essence. — O'xalis Acetosella. An indigenous 

 perennial, the leaves of which are among the 

 most grateful of the vegetable acids. Beaten 

 up with fine sugar, they make a refreshing and 

 wholesome conserve. — Bryonia dioica {dis, 

 two, oikos, a habitation ; male and female flowers 

 on different plants). An indigenous perennial, 

 with a large fleshy root, often as thick as a 

 man's thigh, and annual climbing stems with 

 cucumber-like leaves and greenish flowers. 

 The root abounds with an acrid principle, 

 which, however, can be so dissipated, by repeated washings in water, as to 

 leave a fecula similar to what is yielded by the potato ; and which, in the 

 scarcity which followed the French Revolution, was resorted to as food, and 

 found to be very nutritious. Before being washed, if given in over-doses, 

 the root is an acrid poison. Medicinally, it was formerly much extolled 

 as a cathartic and diuretic, but it is seldom employed at present.

Daphne Mezheum, Thymelese ; which, independently of being one of our 

 earliest-flowering and most odoriferous native shrubs, is also " a stimulating 

 diaphoretic, useful in chronic rheumatism." — Canella alba, ikfeliacese, the 

 bark of which is sometimes used as cinnamon, and which, combined with 

 aloes, forms the popular remedy, hiera picra. — iSpartium scoparium, the 

 tops of which have long been celebrated for their cathartic and diuretic 

 powers. — ^'sculus J^ippocastanum, the fruit of which consists almost 

 entirely of fecula, from which has lately been obtained a new vegetable prin- 

 ciple called esculine, which is said to possess alkaline properties, and to act 

 as a febrifuge.
