Demonstrated in Researches Upon Wood-Spirit and Vinous-SpiritDuring the preceding ten years, I have been occasionally con sulted as an analytical Chemist, concerning various commodities of importation, by the Hon. Commissioners of Customs, and have had the good fortune to merit and obtain their confidence in the results of my analyses, and in my professional. Reports. In this long period of probation, out of several hundred cases, some of them delicate and complex, not one has been found in fault, so as to put either the revenue or its collectors in jeopardy. Ihold, how ever, no oflicial appointment, and receive no salary, being paid, as other Chemists were paid before me (and in some special instances since my employment), two guineas for each analysis, whether difficult or easy, whether costing the labour of two days or two hours. In some years, twenty or thirty cases may have occurred, in others, as in. The last year, only five or six, so that the emolument cannot be an object of cupidity to a professional man of any respectability. If the employment be deemed an honour, it is not without its anxieties and its dangers, as will presently appear.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
