When the animal is killed we are very scrupulous in pouring out the
blood, which we avoid using for any purpose connected with food. On
_every_ occasion of the kind "field doctors" are present to see that all
due precautions are taken. They analyse the blood, and if it does not
contain the proper ingredients, the animal is looked upon as diseased,
and its flesh rejected as so far unwholesome; in our climate it would be
difficult of digestion, and produce heaviness, disinclination to study,
despondency and other inconveniences. Blood is said to contain the
electricity that, in connection with the electricity on the nerves,
gives action, feeling, pleasure, and pain. Blood, indeed, contains as it
were the material through which the life of the animal carries on its
operations.
