Browne's treatise on the muscles consisted of six lectures, illustrated by copperplates. It was, however, a plagiarism, as was pointed out by James Yonge: it put together text from the Muskotomia by William Molins with illustrations from the Tabula anatomicae of Giulio Casseri. Nevertheless, Browne's book was popular, and underwent ten editions.
The fifth edition of Browne's book, published in 1697, included on pp. 99-105 the first posthumous publication of Richard Lower's An appendix of the heart and its use; With the circulation of the blood, and the parts of which the sanguinary mass is made, etc.
