Sir Robert McCarrison had a big colony of rats/
which he dividsd into different groups. They weie
all put in identical cages, kept under identical
conditions* The degree of cleanliness achieved was
indeed remarkable ; in a room where 1189 lats were
housed, there was not a trace of bad odour. But the
food of the different groups of rats was different.
One set was getting just the right type of food
—chapatis made of wholemeal wheat flour and
lightly smeared with fresh butter, sprouted pulse,
fresh/ raw carrots and raw cabbage in unlimited
quantities, unboiled whole milk/ a small ration of
meat with bones once a week, and an abundance
of water both for drinking and washing. The other
groups of rats were fed on diets of ordinary civilised
people. The result was remarkable. The first set
of rats were specimens of perfect health/ strength
and endurance; disease was entirely abolished.
But in the other sets, it seemed as though the lid
of a veritable Pandora's bos had been opened* The
long list of diseases which they suffered from is
simply staggering. As Dr, G. T. Wrench puts it, as
many diseases as could be packed into the small
body of a rat were present. There was not a single
organ or part of the body which was unaffected.
This should give one food for thought. The only
difference between the first set and other sets of
rats lay in their diets. If one set developed intq
specimens of perfect health/ while others we^
quite the reverse of it/ there can be but one cause-
wrong food. There were so many disease conditicins,
