Referee's report by John Scott Burdon-Sanderson, on a paper 'An attempt to cultivate parasitic protozoa from malignant tumours, vaccinia, molluscum contagiosum, and certain normal tissues, together with infection experiments carried out with the culture media, and a note on the treatment of cancer' by Samuel George Shattock and Charles A Ballance Not recommended for publication in the Proceedings of the Royal Society of London. The investigations have failed in their intended purpose. The abstract already published in the Proceedings is sufficient, but finds it a shame more of the experimental details were not given there. Subject: Physiology [Published in the 'Proceedings of the Royal Society of London', 1895] 23 May 1895
