properties in common with the acrid aromatics ; whence he concludes that 
it is a powerful tonic and antiseptic : the aromatic principle appears to 
reside in a resinous part of, its Substance, which stimulates the intestinal 
canal, and which operates as a gentle cathartic. In many instances the 
stomach cannot support it, unless each dose is accompanied by a few drops 
of laudanum. In intermittent fevers, when taken after the biliary ducts 
have been evacuated by an emetic, it is- often found equal to the Peruvian 
bark. In remittent it is used with as great success as in intermittent 
fevers, and in one instance it was found to operate more successfully than 
the Peruvian bark. In inflammatory disorders, where the phlogistic dia- 
thesis is not very strongly marked, and where a weakness of arterial action 
has taken place, it gives tone and vigor to the stomach. United writh 
laudanum, it has frequently dissipated the alarming symptoms of pulmonary 
consumption when attended with nightly sweats and diarrhoea. A person 
afflicted with catarrh complicated with dyspepsia, which had resisted the 
best chosen remedies, was perfectly cured by this bark. Dr. Young also 
assures us that there is not in the whole materia medica a more certain and 
efficacious remedy in hysterical affections than the bark of Poplar roots 
combined with a small quantity of laudanum ; that taken after the first 
passages have been evacuated, it is a specific in cholera infantum ; in fine, 
that it is ah excellent remedy for worms. It is given in, aqueous extract, 
either in the form of infusion or of decoction, but it is most efficacious 
when taken in substance : the dose for an adult is from one scruple to two 
drachms. 
In Paris, a spirituous liquor is made from the fresh bark of Poplar roots, 
with the addition of a sufficient quantity of sugar to render it agreeable to 
the taste. 
The Tulip Tree was introduced into Europe 60 years ago, and many 
stocks of this species, more than 50 feet high, exist in France, Germany 
and England, which are annually covered with myriads of flowers, and 
which yield productive seeds. It has been so widely spread, within 15 
years, that there are few country seats where it is not found ; and, by the 
fine form of its trunk, by the richness and singularity of its foliage, and by 
the beauty of its flowers, it is eminently fitted to adorn them. It is to be 
desired, on account of the excellent qualities and diversified uses of its 
wood, that it should be multiplied also in our forests.
