“This was a bill filed by the plaintiffs, claiming to have a copyright in a book entitled ‘the Pharmacopoeia of the United States of America,’ against the defendants, for an alleged infringement of their right, by publishing a work under the title of ‘the American Dispensatory,’ by John R. Coxe; in which work, the bill charges, is incorporated nearly the whole of the matter contained in the plaintiffs’ work. The bill further alleges that the plaintiffs, on the 15th of December 1822, deposited the title of their said work in the clerk’s office of the district court of Massachusetts, and took all such other steps and measures as they verily believed were required by law to secure to them the sole property in their said work. The bill concludes by praying an injunction to restrain the defendants from publishing or vending ‘the American Dispensatory,’ and for an account.”
