114 BACTERIA IN DAILY LIFE 



follow the example set by Italy, where the aerated 

 water manufacturers are closely looked after by 

 the State, and no factory may be opened unless 

 a satisfactory guarantee can be given of the 

 chemical and bacteriological purity of the water 

 which is intended to be used, whilst the authorities 

 must also be assured that the methods employed 

 are satisfactory from a hygienic point of view. 

 The sale of all aerated waters prepared from 

 insanitary water-supplies is strictly prohibited 

 by the State. 



It will now be of interest to ascertain what is 

 the result of the endeavours which have been 

 made to explore the bacterial flora of those 

 highly prized and largely circulated natural 

 mineral waters, which abound in so many parts 

 of the world and are practically the making of 

 so many health resorts. 



Perhaps the most exhaustive examinations of 

 mineral water which have been so far made are 

 those published by Dr. Eugenio Fazio, who studied 

 the bacterial condition of some of the celebrated 

 springs situated near Naples at Castellamare, 

 Telese, Acetosella, and Muraglione, care being 

 taken to select examples of different types of 

 water, samples being collected from chalybeate, car- 

 bonated sulphur, and alkaline springs respectively. 



All these various mineral waters were character-
