WASHINGTON, Circuit Justice.
Upon the plea of not guilty, it is incumbent on the plaintiff to prove, not merely that the defendant had made, used, or sold a saddle; but tbn.t it substantially resembled the one for which the plaintiff has obtained his patent. And if the difference between them be only in form, or proportions, they are the same in legal contemplation; since to permit the defendant to shelter himself under a mere formal difference, would be to sanction a fraudulent evasion of the plaintiff's right, and to render the patent law a dead letter. The second section of the patent law, which declares that simply changing the form or proportions of any machine, or composition of matter, shall not be deemed a discovery, affords a sensible and a just rule, equally applicable to an art or manufacture, and has always been so considered and treated. In actions of this kind, persons acquainted with the particular art to which the controversy relates are usually examined for the purpose of pointing out and explaining to the jury the points of resemblance, or of difference, between the thing patented,-and that which is the alleged cause of the controversy; and the opinions of.such witnesses, in relation to the materiality of apparent differences, are always entitled to great respect. But after all, the jury must judge for themselves, ■ as well upon the information so given to them, as upon their own view, where the articles, or models of them, are brought into court. The witnesses, who testified in this case, did not entirely agree in opinion as to the nature of the difference between the plaintiff’s and the defendant’s saddles. Most of them however stated, that it consisted in the workmanship bestowed upon the saddles, and upon their external appearance. You have had an opportunity of examining them, and must decide whether they are, or are not substantially the same. If they are, the plaintiff has made out his case on the general issue; since it is not denied that the defendant had made and used saddles similar to those produced in court, subsequent to the 10th of July, 1819, and before the institution of this action. Another objection to the plaintiff’s right of recovery arises out of the special matter given in evidence, of which notice was given by the defendant to the plaintiff. It is, that the plaintiff surreptitiously obtained this patent for a discovery of one Wimbly, who worked as a journeyman in his shop. If the jury are satisfied that the discovery was in reality made by Wimbly, they must be also satisfied that the patent was obtained in fraud of any right which such discovery bestowed upon Wimbly. For if, upon the evidence, you should be of ojnn-ion, that Wimbly gave up his right of discovery to the plaintiff, by expressly or impliedly permitting him to encounter the trouble and expense of obtaining a patent, it cannot be affirmed that the plaintiff obtained the patent surreptitiously, or in fraud of Wimbly’s discovery.
The next inqury is, whether the saddle for which the plaintiff has obtained a patent, was in use prior to his alleged discovery. The patent bears date the lfith of July, 1819; and Taylor, one of the witnesses, has deposed that the first saddle made in the plaintiff’s shop, upon which the patent was obtained, was about the latter end of May preceding. Hudson swears that he made a saddle like the plaintiff’s, and sold it on the 2Sth of May, 1S19; and Andrews swears, that he. saw a saddle substantially the same, except that the skirts and pad were fastened together, in April of the same year. It is contended by the defendant’s counsel, that the plaintiff’s right is to date from the time when he applied for the patent, which for any thing that appears to the contrary, should be considered as having happened on the same day on which the patent issued. If so. then Hudson’s saddle was made and sold before the plaintiff’s title accrued. But the court cannot yield its assent to the doctrine of the defendant’s counsel. It is incumbent on the plaintiff to show, that the infringement took *760place after the time of his application, or the date of his patent. But, if the defendant attempts to avoid the patent by showing that tile patentee was not the original discoverer of the thing patented, the patent will be considered as relating back to the original discovery. The notice authorized to be given by the sixth section of the law is, that the plaintiff was not the original discoverer, but that the thing patented had been in use. &c., anterior to the supposed discovery of the pat-entee. Taking it for granted that this patent is to date from the latter end of May, there would be some difiiculy in deciding the question of priority between the plaintiff and Hudson, whose saddle was made also the latter end of May. Did the cause turn on this point, the jury should require the defendant to clear up their doubts, by satisfying them that the right of priority was due to Hudson; because upon that fact he grounds the de-fence, and in his notice he undertakes to establish it. But at all events, if the evidence of Andrews be believed by the jury, and If they are also of opinion that the connecting of the skirts to the pad of the saddle, spoken of by this witness, is a mere difference in form from the patented saddle, the plaintiff cannot be considered as an original discoverer. Tliis, if so found by the jury, is fatal to the plaintiff's right.
The last objection, or the second made by tlic defendant, is, we think, fully made out, and is not less fatal to the plaintiff’s recovery. This is founded on the imperfect description of the thing patented, given in the specification. It professes to be an improvement in the manufacturing of saddles without trees. The materials and the manner of making the saddles described are all old, or if there bo any thing new in the combination, or in the application of the old to the new, they are not distinguished; nor doss the specification describe, or attempt to describe in what the improvement consists. It is quite impossible to say. whether it consists in substituting some other material for the tree, so as to constitute an improvement of the old saddle tree; or in adding skirts and flaps to the pad saddle, which was in use long before the date of the plaintiff's discovery, and was made without trees; or whether it consists in all, or any of the other described operations in the malting of saddles. If in all, then the patent is broader than the discovery, since it is clear that the materials, as well as the process in the manufacture, described in the specification, are old. If the improvement consists in any one or more of the particulars set forth in the specification, it ought to have been so stated, in order that other persons might have known how to avoid any infringement of the plaintiff’s right; and that the public might have the benefit of the discovery, by referring to the specification itself, after the expiration of the plaintiff’s monopoly. It is not enough for the plaintiff’s counsel or the witnesses to point out at the trial, or even for the jury to perceive by examination of the thing patented, and comparing it with others before in use, what it is that constitutes the improvement. This would afford no advantage to third persons, and least of all would it afford consolation to the defendant, who, if he has offended at all, did it innocentl3r, and through ignorance, and can make atonement in no .other way, but by submitting to the penalty which the law imposes upon him. and the troubles and expense incident to litigation. Third persons wishing to avoid these consequences, can safely depend upon no other information than what the records of the secretary of state’s office may afford. No description of the discovery secured by a patent will fulfil the demands of justice and of the law. but such as is of record there, and of which all the world may have the benefit. It was insisted by the plaintiff’s counsel, that this specification is perfectly intelligible to an artist, who could experience no difficulty in making such a saddle as is there described; and that if it be not so. still the defendant cannot avail himself of the defect, unless he had stated it in his notice, and also proved at the trial an intention in the plaintiff to deceive the public. But these observations are all wide of the objection, which is not that the specification does not contain the whole truth relative to the discovery, or that it contains more than is necessary. It is admitted that the specification does not offend in either of these particulars. Hut the objection is. that throughout the whole of a very intelligible description of the mode of making the saddle, the patentee has not distinguished what was new, from what was old and before in use. nor pointed out in what particulars his improvement consisted. Upon this objection then, the verdict ought to be for the defendant, whatever the jury may think on the other points.2
Plaintiff suffered a nonsuit..

 The court refused to allow evidence to be given, to prove that saddles like the plaintiff's had been in use in England many years ago. the notice being special and confined to the alleged use within the United .States.
