to deposit its contents, and which, at the same time, may possess @ 
deep black color, not liable to fade, the galls should be macerated for 
some hours in hot water, and the fluid be filtered; it should then be 
exposed, for about sixteen days, to a warm atmosphere, when any 
mould that may have been produced must be removed. A solution of 
sulphate of iron must be employed, which has also been exposed for 
some time to the atmosphere, and which, consequently, contains a cer- 
tain quantity of the red oxide of iron diffused through it. I should — 
recommend ihe infusion of galls to be made of considerably: greater 
strength, than is generally directed ; and I believe that an ink, formed 
in this manner, will not necessarily require the epi of any mu- 
cilaginous substance to render it of a proper consistenc

it improves its color, and gives it an additional lustre. Tees

1. Tincture of Iodine.*—Dr. Joerg, professor of obstetrics at Leip: 
sic, has formed a society for the purpose of determining the proper 
ties of some of the most useful and active medicaments by an actua 
trial of them by the members themselves. The following is the re 
sult with regard to iodine. 
“The positive effect of the tincture of iodine consists in an excile: 
ment of the whole alimentary canal ; it appears to act upon the parie- 
ties of the intestines like a good concentrated salivary and pancreaied 
fluid. Hence, with persons in health there is a saline taste in the 
mouth ; an augmentation of salinary secretion; thus, increase of @P- 
etite, sensible motion of the intestines, slight pains, evacuation of 
wind and fecal matters. But this excitement is transmitted also 
the brain, as happens with most substances which increase the activ- 
ity of the intestinal canal; producing heaviness and pain in the head, 
felt sometimes in one place and sometimes in another. lodine im

and places those organs in a condition approaching to phlogosis: 0% 
actually inflames them. This irritation seems to extend to the intern 
membrane of the nose, since the mucous secretion is increased a5 well 
as the bronchial. » As iodine acts so energetically upon the digesiv’
