delivered the opinion of the court. .
Charles Selden, the testator of the complainant in this case, in the year 1859 took the requisite steps for obtaining the copy
The parties went into proofs, and the various books of the complainant, as well as those sold and used by the defendant, were exhibited before the examiner, and witnesses were examined on both sides. A decree was rendered for the complainant, and the defendant appealed.
The book or series of books of which the complainant claims the copyright consists of an introductory essay explaining the system of book-keeping referred to; to which are annexed certain forms or. blanks, consisting of ruled lines, and headings, illustrating the system and showing how it is to be used and carried out in practice. This system effects the same results as book-keeping by double entry; but, by a peculiar arrangement of columns and headings, presents the entire operation, of a day, a week, or a month, on a single page, or on two pages-facing each other, in an account-book. The defendant uses a similar plan so far as results are concerned; but makes a different arrangement of the columns, and uses different headings. If the complainant’s testator had the exclusive right to the use of the system explained in his book, it would be difficult to contend that the defendant does not infringe it, notwithstanding the difference in his form of arrangement; but if it be assumed that the system is open to- public use, it seems to be equally difficult to contend that the books made and sold by the defendant are a violation of the copyright of the complainant’s book considered merely as a book explanatory of the system. Where the truths of a science or the methods of an art are the common property of the whole world, an$ author has the right to express the one, or explain and use the other, in
The evidence of the complainant is principally directed to the object of showing that Baker uses the same system as that which is explained and illustrated in Selden’s books. It becomes important, therefore, to determine whether, in obtaining the copyright of his books, he secured the exclusive right to the use of the system or method of book-keeping which' the said books are intended to illustrate and explain. It is contended that he has secured such exclusive right, because no one can use the system without using substantially the same ruled lines and headings which he has appended to his books in illustration of it. In other words, it is contended that the ruled lines and headings, given to illustrate the system, are a part of the book, and, as such, are secured by the copyright; and that no one can make or use similar ruled lines and headings, or ruled lines and headings made and arranged on substantially the same system, without violating the copyright. And this is really the question to be decided in this case. Stated in another form, the question is, whether the exclusive property in a system of book-keeping can be claimed, under the law of copyright, by means of a book in which that system is explained? The complainant’s bill, and the case made under it, are based on the hypothesis that it can be.
It cannot be pretended, and indeed it is not seriously urged, that the ruled lines of the complainant’s account-book can be claimed under any special class of objects, other than books, named in-the law of copyright existing in 1859. The law then in force was that of 1881, and specified only books, maps, charts, musical compositions, prints, and engravings. An account-book, consisting of ruled lines and blank columns, cannot be called by any of these names unless by that of a book.
There is no doubt that a work on the subject of book-keeping,
The difference between the two things, letters-patent and copyright, may be illustrated by reference to the subjects just enumerated. Take the case of medicines. Certain mixtures are found to be of great value in the healing art. If the discoverer writes and publishes a book on tbe subject (as regular physicians generally do), he gains no exclusive right to the manufacture and sale of the medicine; he gives that to the
The copyright of a book on perspective, no matter how many drawings and illustrations it may contain, gives no exclusive right to the modes of drawing described, though they may never have been known or used before. By publishing the book, without getting a patent for the art, the latter is given to the public. The fact that the art described in the book by illustrations of lines and figures which are reproduced in practice in the application of the art, makes no difference. Those illustrations are the mere language employed by the author to convey his ideas more clearly. Had he used words, of description instead of diagrams (which merely stand in the place of words), there could not be the slightest doubt that others, applying the art to practical use, might lawfully draw the lines1 and diagrams which were in the author’s mind, and which he thus described by words in his book.
The copyright of a work on mathematical science cannot1 give to the author an exclusive right to the methods of operation which he propounds, or to the diagrams which he employs to explain them, so as to prevent an engineer from using them whenever occasion requires. The very object of publishing a book on science or the useful arts is to communicate to the world the useful knowledge which it contains. But this object would be frustrated if the knowledge could not be used without incurring the guilt of piracy of the book. And where the art it teaches cannot be used without employing the methods and diagrams used to illustrate the-book, or such as are similar to them, such methods and diagrams are to be considered as necessary incidents to the art, and given -therewith to the public; not given for the purpose of publication in other works explanatory of the art, but for the purpose of practical application.
Of course, these observations are not intended to apply to ornamental1 designs, or pictorial illustrations addressed to the taste. Of these it may be said, that their form is their essence,
Recurring to the case before us, we observe that Charles Selden, by his books, explained and described a peculiar system of book-keeping, and illustrated his method by means of ruled lines and blank columns, with proper headings on a page, or on successive pages. Now, whilst no one has a right to print or publish his book, or any material part thereof, as a book intended to convey instruction in the art, any person may practise and use the art itself which he has described and illustrated therein. The use of the art is a totally different thing from a publication of the book explaining it. The copyright of a book on book-keeping cannot secure the exclusive right to make, sell, and use account-books prepared upon the plan set forth in such book. Whether the art might or might not have been patented, is ‘a question which is not before us. It was not patented, and is open and free to the use of the public. And, of course, in using the art, the ruled lines and headings of accounts must necessarily be used as incident to it.
The plausibility of the claim put forward by the complainant in this case arises from a confusion of ideas produced by the peculiar nature of the art described in the books which have been made the subject of copyright. In describing the art, the illustrations and diagrams employed happen to correspond more closely than usual with the 'actual work performed by .the operator who uses the art. Those illustrations and diagrams consist of ruled lines and headings of accounts ; and
The remarks of Mr..Justice Thompson in the Circuit Court in
Clayton
v.
Stone
&
Hall
(
The case of Cobbett v. Woodward (Law Rep. 14 Eq. 407) was a claim to copyright in a catalogue of furniture which the publisher had on sale in his establishment, illustrated with many drawings of furniture and decorations. The defendants, being dealers in the same business, published a similar book, and' copied many of the plaintiff’s drawings, though it was shown that they had for sale the articles represented thereby. The, court held that these drawings were not subjects of copyright. Lord Romilly, M. R., said: “This is a mere advertisement for the sale of particular articles which any one might imitate, and any one might advertise for sale. If a man not being a vendor of any of the articles in question were to publish a work for the purpose of informing the public of what was the most convenient species of articles for household furniture, or the most graceful species of decorations for articles of home furniture, what they ought to cost, and where they might be bought, and were to illustrate his work with designs of each article he described, — such a work as this could not be pirated with impunity, and the attempt to do so would be stopped by the injunction of the Court of Chancery; yet if it were done with no such object, but solely for the purpose of advertising particular articles for sale, and promoting the private trade of the publisher by the sale of articles which any other person might sell as well as the first advertiser, and if in fact it contained little more than an illustrated inventory of the contents of a warehouse, I know of no law which, while it would not prevent the second advertiser from selling the same articles, would prevent him from using the same advertisement; provided he did not in such advertisement by any device suggest that he was selling the works and designs of the first advertiser.” •' ■ .

The conclusion to which we have come is, that blank account-books are. not the subject of copyright; and that the me.re copyright of Selden’s book did not confer upon him the exclusive right to make and use account-books, ruled and arranged as designated by him and described and illustrated in said book.
