Excerpt from The Australasian Medical Gazette, Vol. 25: The Journal of the Australasian Branches of the British Medical Association; From January to December, 1906 It has been taken for granted, so far as we are aware, that the amount of the homo logons proteid in solution determines the amount of the precipitate, and that it is the throwing out of the proteid from solution that constitutes the precipitate. Hence the term precipitable substance is commonly regarded as equivalent to the homologous proteid, and this conception of the interaction has dominated all hypotheses and statements regarding it. We do not propose to discuss more fully here the nature of the interaction, but merely to point out that, so far as our observations go, we are led more and more definitely to the conclusion that the great bulk of the substance that is thrown out of solution in precipitin reactions and that goes to form the precipitate is supplied by the antiserum and not by the test proteid, and that whatever part in the reaction is played by the test proteid, it is not merely that of supplying a substance to be thrown out of solution by the precipitin antiserum.
