Partly by reason of Marchand's energy, no nostrum in the country has been so widely attacked as the Chicago product. Occasional deaths, attributed (in some cases unjustly) to its use, have been made the most of, and scores of analyses have been printed, so that in all parts of the country the true nature of the nostrum is beginning to be understood. The prominence of its advertising and the reckless breadth of its claims have made it a shining mark. North Dakota has forbidden its sale. San Francisco has decreed against it; so has Lexington, Ky., and there are signs that it will have a fight tor its life soon in other cities. It is this looming danger that impelled Liquozone to an attempted reform last summer. Yet, in spite of the censorship of its legal lights, in spite of the revision of its literature by its scientific experts, in spite of its ingenious avoidance of specifically false claims in the advertising which is being scattered broadcast to-day, Liquozone is now what it was before its rehabilitation, a fraud which owes its continued existence to the laxity of our public health methods and the cynical tolerance of the national conscience.
