Scientific paper not by Kekwick

"The Fifth Coagulation Factor ('Factor V'). Preparation and Properties" by P.A. Owren, from The Biochemical Journal, vol.43 no.1, 1948.

This paper was received at the same time as Kekwick's own papers, although his name does not appear on it. Its subject matter and links to the Lister Institute and Medical Research Council suggest that Kekwick was involved in advising or mentoring.
