* These goods are generally sold by the lineal yard; it must, therefore, be noted that the duty per lineal yard will vary according to the width; thus, 100 yards yard wide would be charged as 75 square yards, the same quantity 1 yards wide, 125 square yards, and so on.

*If, on examination, any drugs, medicines, medicinal preparations, whether chemical or otherwise, including medicinal essential oils, are found, in the opinion of the examiner, to be so far adulterated, or in any manner deteriorated, as to render them inferior in strength and purity to the standard established by the United States Edinburgh, London, French, and Germa

pharmacopoeias and dispensatories,* and thereby improper, unsafe, or dangerous to be used for medicinal purposes, a return to that effect shall be made upon the invoice, and the articles so noted shall not pass the Custom House.

"It is not conceived to be the intention of the law that the articles referred to should conform in strength and purity to each and all of those standards, as such conformity is believed to be impracticable, owing to the variations in those standards. If, therefore, the articles in question be manufactured, produced, or prepared in England, Scotland, France, or Germany, as the case may be, and prove to conform in strength and purity to the pharmacopoeia and dispensatory of the country of their origin, said articles become exempt from the penalties of the law. All articles of the kind mentioned, produced, manufactured, or prepared in any other country than those before mentioned must conform in the qualities stated to the United States pharmacopoeia and dispensatory. With a view to afford a reliable guide to the examiner of drugs and medicines, as well as to the analytical chemist, on appeal, in ascertaining the admissibility of such articles under the provisions of law, founded on their purity and strength, the following list is given of some of the principal articles, with the result of special tests agreeing with the standard authorities referred to in the law; all of which articles are to be entitled to entry when ascertained by analysis to be composed as noted, viz. :Aloes, when affording 80 per cent. of pure aloetic extractive.

Essential or volatile oils, as well as expressed oils, used in medicine must conform in purity to the standards of specific gravity noted and declared in the dispensatories mentioned in the Act.

Patent or secret medicines' are by law subject to the same examination and disposition after examination as other medicinal preparations, and cannot be permitted to pass the Custom House for consumption, but must be rejected and condemned, unless the special examiner be satisfied, after due investigation, that they are fit and safe to be used for medicinal purposes."

Invoices of Earthenware which merely give the aggregate value of the several crates without specifying the items contained therein, not being such as are required by law, will, when presented, be treated as null and void, and entry of the earthenware refused until proper invoices are obtained and produced by the importers (the merchandise in the meantime being treated as unclaimed), or it may be admitted upon giving bonds to produce proper invoices.
