Aiter carelul inquiry, it is said that the English professional man heads the list as the taKest of adult males, reaching an average height of five feet nine inches, and a fraction over. The next tallest men are Americans, only a tiny -f ractioa lesa tall than their English biothers.

The rain can be secn falling from the clouds high above the desert, but wheu the water reaches the strata of hot, dry air beneath the clouds it is entirely absorbed before falling half the distance to the ground. It is a singular sigla to' witness a heavy downpour of rain, not a drop of which touches the RTouml.

Nehring 10 be th oldpst human teeth yet found i ; rope. One of them, a permanent molar, is remarkably Hke that of impanzee, but not much like that of the gorilla or orang. He also calis iition to the fact that the first remolar and last molar are reduced in t-ize in modern man as compaxed with eaiiy man.
