the striped pieces have externally the cinnamon-brown colour 
of their inner surface, and are free of cracks and wrinkles. They 
are from eight to eighteen inches long, between a line and half 
an inch in thickness, and from one to four inches in breadth 
(Christison, Disp., p. 823). 
PuystotocicaL Errects.—On Animals. Dr. Freind (Com- 
ment., c. xiv.) states that an ounce and a half of a strong 
decoction of bark, injected into the jugular vein of a dog, caused 
violent palpitation of the heart and frequent spasms; half an 
ounce more produced tetanus and death. 
On Man.—The topical effects are astringent or slightly irri- 
tant; the constitutional effects are principally manifested by the 
disordered condition of the vascular and cerebro-spinal systems. 
In some conditions of the system, Cinchona operates as an irri- 
tant or stimulant. Pereira (Elements of Materia Medica, art. 
Cinchona, p. 1091) has the following observations: “If a man 
in a state of perfect health take a small dose of bark, no obvious 
effects are produced, or perhaps a little thirst, with some slight 
disorder of the stomach, or a temporary excitement of the 
stomach, may be brought on. If the dose be increased, the 
alimentary canal becomes disordered (indicated by the nausea, 
vomiting, loss of appetite, thirst, and constipation, or even purg- 
ing); a febrile state of the system is set up, manifested by the 
excitement of the vascular system and dry tongue, and the 
cerebro-spinal system becomes disordered, as is shown by the — 
throbbing headache and giddiness.” 
Mepica Usrs (Homaoparuic).— Hahnemann’s observations: 
“Next to Opium, China is, of all medicines, that which has 
been most abused, to the great injury of mankind. It was not 
only held to be incapable of doing harm, but esteemed the most 
safe and efficacious of remedies in almost all diseases, especially 
where there was debility, and it was often given for weeks and 
months together, in strong doses, repeated several times a day.

fies the reproach I have so frequently cast upon medical practi-
