MEDICINAL PREPARATIONS OF GOLD, 1g;r 



corroding one of the corpora cavernosa he found them of of the prepar- 

 real advantage : but the most striking instance of their em- ation ? of gold. 

 cacy was in a cancerous ulcer, that had destroyed the upper 

 lip, attacked the soft parts of the nose and left cheek, de- 

 stroyed the square bones [os caries], and rendered the max- 

 illary bone carious. Being called to a consultation with 

 Dr. Payen on this very serious case, in which all the common 

 methods had been tried in vain, Dr. Duportal hoped to op- 

 pose the progress of the disease by the use of Dr. Chrestien's 

 medicine assisted by attenuant extracts. Jn consequence 

 the patient was directed daily to rub into the gums the triple 

 muriate of gold and soda ; and to take oxide of gold precipi- 

 tated by potash, with pills composed of the extracts of white 

 henbane, hemlock, and sharp-pointed toadflax. The ulcer 

 was daily washed with Sydenham's liquid laudanum, 

 sprinkled over with powder of red bark and camphor, and 

 dressed with a digestive in which oxide of gold was mixed. 

 Under this treatment, which has been continued two months 

 gradually increasing the dose of the substances, the ulcer 

 has assumed a promising appearance; the carious points 

 have disappeared; the suppuration furnishes laudable pus 

 in moderate quantity ; the patient daily improves in flesh 

 and strength ; and thev-e is every reason to believe, that this 

 evident melioration will continue. That it cannot be ascribed 

 to the means employed in conjunction with the preparations, 

 of gold is evident, for they had been used previous to these 

 without effect.
