To quickly assess the difficulty of the text, read a short excerpt:
In some of these apparatus an electric bell has been connected with the thermometer in a manner to close the contact and ring when the quicksilver has risen to the prescribed degrees of heat ; but as the heating has to be done very gradually, or a large number of bottles will crack and burst, the operator's hand is re- quired constantly on the steam valve and his eye on the thermometer, so that this electrical arrangement becomes entirely superfluous. The inconvenience of losing bottles and the...ir con- tents by bursting was practically overcome by the immersion of the bottles in a water bath, and the success of this simple expedient seemed to prove a lasting one until a singular ' defect to it appeared, which very speedily caused the abandonment of the water sterilization as far as it was applied in the pro- duction of normal infants' milk. It was' found that the bottles used in the water sterilization began, in the course of time, to loose their brilliancy, their sur- face becoming dull and gritty by the action of minute particles of lime which were deposited by the boiling ■water, and which defied all efforts to remove them by mechanical or by chemical means of cleansing.
