96 ORD. II. Amentacee. QUERCUS ROBURs 
Two sorts of galls are distinguished in the shops, one said to be 
brought from Aleppo, the other from the southern parts of Europe. 
The former are generally of a bluish colour, or of a greyish, or black, 
verging to blueness, unequal and warty on the surface, hard to 
break, and of a close compact texture: the others are of a light 
brownish or whitish colour, smooth, round, easily broken, less com- 
pact, and of a much larger size. The two sorts differ: only in 
strength, two of the blue galls being supposed equivalent in this 
respect to three of the others.° 
Galls appear to be the most powerful of the vegetable astringents, 
striking a deep black when mixed with a solution of ferrum vitrio- 
latara; : and therefore preferred to every other substance for the 
purpose of making ink. As a medicine, they are to be considered 
as applicable to the same indications as the Oak -bark, and by 
possessing a: greater degree of astringent and styptic power, seem to 
have an advantage over it and to be better suited for external use. 
Reduced to Gite. powder, and made into an ointment, wid have 
been found of Great. service in Ee ettidat affections." Their 
efficacy in intermittent fevers was-tri Mr»Poupart; by order of 
the Academy of Sciences, and from his report it appears, that the 
Galls succeeded in many cases; and also that they failed in many 
other cases, which were afterwards cured by the Peruvian bark.’
