Angelica, each four ounces ; Alcohol aquosi (common brandy,) thirty 

 six pounds; Tincture of Juniper, twelve pounds* Keep forty days, 

 and filter. This preparation is given in the dose of half an ounce 

 to an ounce, united with a camphorated portion. This drug is only 

 the supplement to a preceding one, which consists of eighty drops of 

 Laudanum, a wine glass full of brandy, and two spoons full of Cas- 

 tor oil ; another dose of brandy to which are added forty drops of 

 Laudanum is sometimes given* (Medical Reposit. Feb. 1826, and 

 Bull, de Ferussac Sc. med. VIII, 149.) 



The missionaries of Serampore assure us that this medicament 

 cures in India almost all the sick when it is administered in time. I 

 do not doubt, that the action of this drug, which on all other occa- 

 sions would be qualified as inflammatory > should be attributed entire- 

 ly to the aloes, which enters into its composition in scruple doses ; 

 the other substances, including even the myrrh, being but insignifi- 

 cant drugs. In the advice which I have given for the employment 

 of aloes against cholera, I had, by induction, another practical fact* 

 which I ought not to pass over in silence. Mr. Barberet, apotheca- 

 ry at Baume (Cote-d'Or) has assured me that the Polish refugees in 

 their passage through that city gave to their hosts the recipe of an 

 anticholeric liquid. It was simply that of the elixir of long life or of 

 compound aloes, which they said had always been employed with 

 success, and which they believed even to be an excellent prophylac- 

 tic. I cannot neglect these notices, for popular remedies are not al- 

 ways the least efficacious ; they are often it is true, the fruits of blind 

 empiricism ; but those which really exert some action, have in their 

 favor a multiplied experience which physicians should not disdain to 

 verify, while endeavoring to obtain a positive idea of their mode of 

 action in diseases. — Bib. Univ.,Aout, 1832*

Dear Sir, — The appearance in a late number of the American 

 Journal of Science, of an account of certain singular cases of hydro- 

 phobia, will probably render acceptable to your readers some inlbr-
