438 PATENT MEDICINES AND SECRET REMEDIES. 



A French journal recommends a collodion containing: ten per cent, of 

 its weight of sulphocarbolate of zinc, as giving excellent result. The solu- 

 tions of corrosive sublimate and other mercurial salts, often used for the- 

 purpose, are more or less dangerous, and should be avoided. The following 

 lotion, which contains only a minute proportion of mercary, is harmless and 

 well recommended : 



R Hydai'g. perchlor gr. v. 



Acid, hydrochlor gtt. xxx. 



Sacch. alb. 



•o 



Spt. vin. rect 5 ij. 



Aquffirosae 5 vii. 



The following formula is also highly recommended : 



R Sulphocarbolate of zinc 1 part. 



Collodion 45 parts. 



Oil of lemon 1 part. 



Absolute alcohol 5 parts. 



The sulphocarbolate of zinc should be reduced to an extremely fine 

 powder, and should then be thoroughly incorporated with the fluid mixture. 

 Here is an other, in which white mustard-seed and lemon juice are the 

 chief ingredients . 



R Pulv. sinajiis alb 5 iij. 



Olei amygdal 5 ss. 



Sued limonum, enough to make a thick paste. 

 Mix. To be applied as an ointment. 



It is also said that powdered nitre, moistened with water, and applied 

 night and morning, will soon remove all traces of freckles. An old fash- 

 ioned household prescription is sour milk or butter milk, which may some- 

 times answer the purpose. — Boston Journal of Chemistry. 



Ammoniated Tincture of Guaiacum por Inflamed Throats. — Dr. Gar- 

 ner, in the Canada Lancet, recommends the use of ammoniated tincture of 

 guaiacum in inflammation of the throat whether acute or chronic. The 

 remedy, he says, seems to be totally unknown to some practitioners, and 

 wholly ignored by others. He prescribes it with almost invariable success- 

 in cases of chronic hoarseness, employing it in the form of a gargle. In the 

 first stage of quinsy its action is astonishing. In cases of inflamed tonsils- 

 or sore throat, when produced by or accompanying measles, scarlatina, 

 eynanche, parotiditis, and croup, »he uses the pure tincture by means of a 

 Bponge-probang, His formula for a gargle is as follows :
