134 Eupatorium perfoliatum., 
ague-weed. Imitating their practice, many country physicians of 
respectability use it as a substitute for Peruvian bark in these affec- 
tions. Their reports are uniformly favourable to. the powers of 
the article in curing those fevers, unassisted by any other medi- 
cines. This practice is particularly common in the middle and lower 
parts of Jersey, where I have had opportunities of knowing that this 
plant was successfully used by practitioners of medicine, and in do- 
mestic practice, in the treatment of many of the different types of 
intermittent fever. Dr. Anderson, in his inaugural thesis, enumerates 
and details some cases of quotidian, tertian, and quartan intermittents, 
in which the bone-set had, under his own observation, performed 
cures. His favourable accounts are supported by the testimony of 
Dr. Hosack, who has frequently prescribed the article in the treat- 
ment of intermittents. I am not able to offer any corroborative testi. 
mony in favour of this plant in these affections, never having used it 
in them. Dr. Barton says, that in decoction it has been efficaciously 
administered in the hot stage of simple intermittents. The copious 
perspiration produced when thus given warm, is highly beneficial, 
and it is this effect which has given the plant the appellation of 
“ vegetable antimony.*? The Doctor, however, seemed to think, that 
to the heat of the water when employed in this manner, was greatly 
owing the diaphoretic effect; and, unaided by this adventitious cireum- 
stance, he doubts whether the determination to the skin can equal 
that of Polygala seneka. In cold infusion I have not been able to 
see any very decided or remarkable diaphoretic effect from it.
