Yoga Makaranda, English translation (2006) from the Tamil version published in 1938, (originally published in Kannada in 1934):
p. 18: For example, everybody knows that pure cow's milk gives good health and happiness. Yet if it is poured in a cup made of pig's skin or dog's skin, it turns into poison and becomes harmful.
TV ad JS 1.3.7 (see also Kataoka 2011: II 400):

tāny anupayogyāny avisrambhaṇīyāni ca śvadṛtinikṣiptakṣīravad iti manyāmahe.
