Gentlemen: — I have carefully examined the solution called "Lloyd's 

 irydrasitit," supposed to contain Hydrastin, the white alkaloid of Hydrastia. The 

 sample examined was purchased from B. O. & G. 0. Wilson, of Boston. The 

 solution is a glycerine preparation. ]t contains Alumina and Magnesia, and traces 

 of an organic base, Vvliich may be Hydrastin ; — the quantity is too small for deter- 

 mination. The white precipitate caused by the addition of Ammonia-water to 

 " Lloyd's Hydrastis" is a mixture of hydrate of Alumina and hydrate of Magnesia, 

 and is not an alkaloid. A pint bottle of " I^loyd's Hydrastis" contained 19', grains 

 of Alumina and 15:5 grains of Magnesia. 



Yours very tiuly,

The analysis of the secret compound yclept " Lloyd' !< Hydrastis" has been in 

 our possession for nearly a year past; hence the statements which have been made 

 to physicians concerning tlie article. The time has come when proU-etiuv should l)e 

 afforded the medical profession by boldly exposing the alleged scientific work of 

 pseudo chemistry. 



The "Jugglery of Chemistry" (see Professor Howe's article on "Asrpsin," pt^jie 

 241, May number of the Eclectic Medical Journal) has been cariied too far:— the 

 skill of the expert analyst unmasks fraud in meilicine; lays bare the specious 

 claims of the pretender ; and protects the honest manufacturer, physician and 

 general public alike against adulteration, sophistication and false allegations as to 

 medicinal strength and composition ; whether in fond, drink or medicine. 



Conclusions. 



When you order a preparation of Hydrastis, be sure yon get it. Alum and 

 Magnesia may be valuable medicinal agents; but their substitution for the expen- 

 sive White Alkaloid of the Ciolden Seal is a yross abuse of confidence, and should 

 receive the condemnation of every lionest practitioner of medicine. 



The analysis of other experts will follow, provid<.-d the privilege of this page 

 is not denied us.
