    s SrB-fJuoup A.—Schools in which Sj)ccial Precautions are taken, including; tiil)erculin te.st, 1. Sterili.sation of milk on the school |)remises, ‘i. Boilinpj of milk on school premises, 8. [Note : Tulx'rculin test may ensure protection against tulx'rculosis, from which nil the schools are returned as exempt. It does not profess to ])rotect against the other maladies, and no boiling or sterili.'^ation is employed as well. Average age of j)U])ils in this school, 1*2 years (10 to 14.)] Twelve Schools—.\os. R, 8, 9, 10, 12, 13, 21, 23, 2R, 38. 39, 42. Ten of these obtain their milk from “general'’ sources, hut boil or sterilise it on the j)remises. Two have their own school dairy farms. In one of the.se the cows on the farm are te.sted ; in the other the milk is boiled on the premises. Only one school, which has its ow'n dairy farm and also boils the milk, makes any return of illness traceable to milk—vi7., 50 cases of diarrhoea (attributed to the cows having eaten acorns), and 35 ca.ses of sore throat (which occurreil while the milk was being supplied from a source other than the school’s own dairy farm). This w'ould seem to show that the boiling of such milk does not destroy the toxin, ferment, or irritant which makes acorns an injurious adilition to the human dietary, or prevent the occurrence of every form of the milk poisoning which produces epidemic .'<ore throats. Taken as a group, the.se 11,408 ]uipils, re])resenting 08,455 yearly observations, make the following return of illness due to milk-infection :— Disease. Diarrheoa . Sore throat. Cases. 50 35 Per cent, per annum. •0073 *(M)51 Percentage of pupils. •043 •03(> The average age of the pupils is 13 years (4 lo IS). Moreover, in one school (Xo. 23) in which milk su])plie<l from a general source is boiled on the school premises, “many” cases of e])idemic sore throat are doubtfully attributed to milk-infection. SrK-(lKOUP B.— Special Prccautittns taken, but only partial in their character or in their ap])lication, ificluding occasional or ])artial boiling of milk on tlie school premises, su])ervision of the sources of supply by the .school, or ins]>ec- tion of the same by the school .Sletlical Ofticer of Health.
