FILTH AS infants' FOOD 119 



regulation which anticipated by thousands of years 

 the findings of modem science. The extreme im- 

 portance attached to cleanliness may be judged 

 from the strict regulation which forbade the Jew to 

 drink milk bought from a non-Jew, unless the milking 

 process had been carried on, or at least watched, by 

 a Jew. Milk was one of the seven articles of food 

 named as being especially liable to receive impurity 

 by exposure and contamination; and it was one of the 

 three beverages which, if left over night imcovered, 

 should not be used, "because it is possible that a 

 serpent may have left its venom therein." All these 

 Rabbinical regulations concerning the use of milk" 

 are quite in harmony with the requirements of modem 

 science, a fact which is in itself a wonderful tribute 

 to Rabbinical wisdom and to the Jewish people.
