Attention was first directed to the presence of a substance in milk acting as a complement by Pfaundler and Moro(1) and from that time onwards there has been much conflicting evidence published on this subject. Kopf(2) stated that complement could not be demonstrated in milk, using the method of Pfaundler and Moro, and the work of Sassenhagen and Bauer(3) would seem to show that complement is not present in milk unless the milk of cows suffering from mastitis be present. Sassenhagen(4) in a later paper states that complement is present in the colostrum of cows and goats and that it disappears as lactation progresses. Lane-Claypon(5) has followed Pfaundler and Moro and states that complement can be found in almost any milk.
