...Consensus of anthropologists is that man is descended from a generalized type of Dryopithecus, an extinct ape whose fossil remains have been widely found...

Some fossil men have also supposed that, on account of their great weight, the monsters had to stay in the water all the time for its buoying effect-that on dry land their legs would buckle. Others disagreed...
...detail with which the fossil is preserved will enable the hitherto impossible comparison of the sexual generation of ancient plants with that of the living relatives...
...fossil is so perfectly preserved that the generative elements, which are often indiscernable in living organisms, can be seen. Moreover, although the original plant fiber has disappeared, the oil has been preserved, in a hardened state, thus forming a perfect mummified picture of the cells. Whether this oil has been an important source of natural petroleum is a question geologists have been studying for years...
...important discoveries were reported by the Department of Biology during the summer. On the Illinois prairies William C.
