INHABITANTS OF THE CLIFFS.

Innumerable gulls and murres breed on the steep cliffs, the latter

most abundant. They kept up a constant din of domestic notes. Some of

them are sitting on their eggs, others have young, and it seems

astonishing that either eggs or the young can find a resting place on

cliffs so severely precipitous. The nurseries formed a lively

picture--the parents coming and going with food or to seek it,

thousands in rows standing on narrow ledges like bottles on a grocer's

shelves, the feeding of the little ones, the multitude of wings, etc.

M. Bouchut's experiments with pepsine for destroying worms in the

stomach and bowels have been continued with extremely promising

results. Even the tapeworm succumbs to the digestive action of pepsine

in large doses, while the more highly organized tissues of the stomach

are unaffected.
