in reality white lead or cerussa; and if it be bismuth, it may be 

 equally deleterious. 



Mr. Y had acquired the gutta rosea on his nose, and ap- 

 plied a saturnine solution on it tor a few nighis, and was then 

 seized with paralysis on one side of his face; which, however, he 

 gradually recovered, and has since acquired the gutta rosea on 

 other parts of his face. 



These fatal effects were probably caused by the disagreeable 

 sensation of an inflamed liver, which used before to be relieved 

 by the sympathetic action and consequent inflammation of the 

 skin of the face, which was now prevented by the stronger stimu- 

 lus of the application of calx of lead. The manner in which dis- 

 agreeable sensations induce epilepsy and palsy, is treated of in 

 Class IIL In some cases where habitual discharges, or erup- 

 tions, or ulcers, are stopped, a torpor of the system may follow, 

 owing to the want of the accustomed quantity of sensation or irri- 

 tation. See Class 1.1.2. 9. and II. 1. 5. 6. In both these si- 

 tuations, some other stimulus should be used to supply the place 

 of that which is taken away; which may either be perpetual, as 

 an issue; or periodical, as a cathartic repeated once a fortnight 

 or month. 



Miss W. an elegant young lady, of about twenty, applied a 

 mercurial lotion to her face, which was covered with very small 

 red points (which seemed to have been not acquired by any 

 known or avoidable means); she was seized with inflammation 

 of her liver, and, after repeated bleeding and cathartics, recov- 

 ered; and in a few weeks the eruption appeared as before. 



M. M. Five grains of calomel once a month, with a cathar- 

 tic, five grains of rhubarb and a quarter of a grain of emetic tar- 

 tar every night for many weeks. With this preparation mercu- 

 rial plasters, made without turpentine, and applied every night, 

 and taken off every morning, will sometimes succeed, and may 

 be used with safety. But blistering the face all over the erup- 

 tion, beginning with apart, succeeds better than any other means, 

 as I have more than once experienced. Something like this is 

 mentioned in the Letters of Lady Mary Wortley Montague, who 

 blistered her face with balsam of Mecca. 



Mrs. F. had for many years had a disagreeable looking erup- 

 tion on her chin. After a cathartic with calomel, she was ad- 

 vised to blister her whole chin; on the healing of the blister, a 

 few eruptions again appeared, which ceased on the application 

 of a second blister. She took rhubarb five grains, and emetic 

 tartar a quarter of a grain, every night for many weeks. 



Miss L. a young lady, about* eighteen, had tried variety of ad- 

 vice, for pimples over the greatest part of her face, in vain. She
