1967 Proc. Royal Soc. B. 168 355 Pasteur..made his classic discovery that sodium ammonium racemate gives a mixture of the crystals of the dextrogyral and laevogyral tartrates.

2. A substance which is a racemic mixture.

1897 Jrnl. Physical Chem. 1 440 The dextrorotary and laevorotary forms crystallize below 8° and the racemate above 15°.

1907 Jrnl. Chem. Soc. 91 i. 906 In the case of substances known only in the liquid state, no general method has as yet been obtained to establish in a sufficiently convincing manner the existence of liquid racemates.
