in improving its medicinal virtues, it still remained to be proved, 
by actual experiment, that the hoped-for success was not merely 
conjectural. To ascertain this, I gave some of my powder to 
Dr. Crichton, Dr. Babington, and Mr. Abernethy; gentle- 
men whose extensive practice and acknowledged skill suffici- 
ently enabled them to judge of its medical properties. They all 
concur in opinion, that, in its general effects, it agrees with Dr. 
James’s Powder and the Palvis Antimonialis ; but, that it is 
more mild, and consequently may be given in larger quantities, 
seldom producing nausea or vomiting, in doses of less than eight 
or ten grains.
