In February 1665 Lower successfully transfused dogs with blood.

First transfusion of blood performed on a human in England, Nov. 23, 1667.

Lower was the first to demonstrate the scroll-like structure of the cardiac muscle. He was one of the first to transfuse blood. Chapter III of the above work records how Lower injected dark venous blood into the insufflated lungs; he concluded that its subsequent bright red color was due to its absorption of some of the air passing though the lungs. The British Museum copy of this book bears the signature of Walter Charleton, followed by the date “1668”; it is possible, therefore, that the book actually appeared in that year and not in 1669. Facsimile, with translation, London, 1932.

With Schneider, Lower overthrew the idea that nasal mucus originated in the brain. This discovery localized nasal catarrh in the air passages and put an end to the use of many recipes for “purging the brain”. The Dissertatio was reprinted separately in 1672 and this was reprinted in facsimile with translation, biographical notes, and a bibliographical study by Richard Hunter and Ida Macalpine, 1963.

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.
