THE MOST RECENT WORK. 



The New Publication. — The Pharmaceutical 

 Journal and '1 transactions ( 1894, 380), recently in- 

 advertently credited an article to a certain Amer- 

 ican publication, in which it appeared as original 

 matter. The editor subsequently learned, -how- 

 ever, that this article was original in another 

 American journal, the one having given no 

 credit to the other when it was due. The ed- 

 itor of the Pharmaceutical Journal and Trans- 



actions, in speaking of his own innocence in 

 the matter, and regret for inadvertently giving 

 credit when not due, says also : " Such venial 

 errors are at times unavoidable in the face of 

 the peculiar system followed by many editors, 

 who seem to prefer to take responsibilities they 

 have not incurred rather than quote the source 

 of their ' original ' articles, translations and 

 abstracts. In pharmaceutical journalism we 

 are probably the greatest sufferers by this prac- 

 tice, which is indulged in much too freely by 

 some of our transatlantic contemporaries. 

 Whilst only too pleased to find our subject 

 matter regarded as of sufficient importance to 

 be worthy of more or less extensive repro- 

 duction, we venture to submit that it is not too 

 much to expect proper acknowledgment to be 

 made in every instance. In such cases as the 

 one which has given occasion for the publica- 

 tion of this note, apologies are due to those who 

 are misled by the omission to furnish such ac- 

 knowledgment, no less than to the original 

 publisher of the information. It may occasion- 

 ally happen, in the pressure of business, that 

 the omission is purely inadvertent, but it is 

 pitiful, to say the least, to see that journals 

 claiming reputation persistently and continu- 

 ally ignore the most elementary notions of 

 courtesy and honesty." 



Spike Oil. — One part by volume of spike oil 

 must give a clear solution with 3 parts of al- 

 cohol of 70^, at a temperature of about 20°.- 

 SchimmeVs Report, Oct., 1894. 



Hydrogen Dioride.— E. L. Patch (Amer. 

 Pharm. Assoc. P/oc., 1894). 



The statement has been made by different 

 authorities that a remarkable difference exists 

 in the medicinal value of Hydrogen Dioxide 

 and its stability. 



Some assert that they get best results from a 

 concentrated solution obtained by evaporating 

 the official 10 volume solution to one-third its 

 volume, producing a 30 volume strength. 



Others pronounce such a product as worth- 

 less. This has led to a series of experiments. 



Using the U. S. P. 1890 process and cold 

 water only, 6,coo Gm. Barium Dioxide }ielded 

 an average for three lots of 13,000 Gm. of 10 5 

 volume solution. 



Using an ice bath, the same quantity of ma- 

 terial gave an average for three lots of 16,700 

 Gm. With extra care 17,500 Gm. were obtained. 

 These assayed 105 volumes, and were far 

 within the requirements for residue and acid- 

 itv.
