The other was composed of the same amount of the silicate with six drops of dilute phosphoric acid and six grains of ammonium phosphate. He filled sterilised tubes, sealed them hermetically, and heated them to 125 or 145 degrees, Centigrade, although 60 or 70 degrees would have killed any bacteria remaining in them. Next he exposed them to sunlight in a south window for from two to four months.
The first step in the disinfection of the hands is the mechanical removal of gross surface dirt and loose epithelium by soap, a stream of running water as hot as can be borne, and a loofah or nail-brush, that has been previously sterilised by heat. The nails should be cut down till there is no sulcus between the nail edge and the pulp of the finger in which organisms may lodge. They are next washed for three minutes in methylated spirit to dehydrate the skin, and then for two or three minutes in 70
In the tropics no milk will keep beyond a certain time limit unless it is sweetened, which renders it less wholesome. I found Nestle & Company's evaporated milk serviceable, but their sterilised natural milk is really excellent, though it is expensive on an expedition which at times has to depend on carriers, and in mountainous regions like New Guinea it would be impracticable to carry it.
As much fuss is made over each young republican as if he were the heir to a long line of kings; his swaddling clothes might make a ducal infant jealous; the family physician thinks $100 or $150 a moderate fee for ushering him into the light of day. Ordinary milk is not good enough for him; sterilised milk will hardly do; "modified" milk alone is considered fit for this democratic suckling.
When stiffness and grating on movement are prominent features we have found the injection of from half to one ounce of sterilised white vaseline afford decided relief.
The phenomena have to be accepted at their face value and allowed to retain a certain empirical complexity; otherwise the seed of all science is sterilised and calculation cannot proceed for want of discernible and pregnant elements.
In the Roman Empire the Occidental provinces finally fell into the hands of the barbarians, chiefly because the Græco-Latin civilisation sterilised the family, reducing the population incurably.
Here each man was supplied with a hot tub, soap and a clean towel, and was issued on stepping out from his tub with freshly-washed underwear, turning his soiled clothes in. This was a splendid system, and when later the clothes were not only washed but sterilised it ensured the men freedom for a short time at least from vermin.
Whatever suspicions he may have entertained unofficially the night before he could now openly and quickly verify. He took a little piece of lung tissue and with sharp sterilised knife cut it up. Then he made it slightly alkaline with a little sodium carbonate, talking half to us and half to himself as he worked.
Moreover as has already been indicated, there are plenty of pupils also who will flourish and probably reach their highest development taught by unscientific men, pupils whose minds would be sterilised or starved by that very nourishment which to our thinking is the more generous.
