The ciliary action in the excretory tubules or nephridia ar- rests one's attention long before the pro- cess is actually mentioned, so perfectly is it portrayed. The reciprocal nature of fertilisation between two worms is made clear by a diagram with moving sperms. The time factor here and in relation to the development of the young worms within the cocoon is explicitly introduced. The film should be preceded and followed by practical work and then shown a second time. An extremely valuable film for any class studying the earthworm in de- tail. . . Excellent photography: the ovaries, living sperms in two stages, and the ne- phridia call for special comment. The diagrams are very helpful. Pace is ap- preciably too rapid in parts. . .

It shows that most aphids have no fathers or even grandfathers. Some are bom alive, while others hatch from eggs; only a few have wings. Ants keep them as cows, while the aphid itself secures its food in an unusual way. It is beset by a host of enemies among which is man. These scenes are supplemented by an animated drawing of the aphid's life cycle."

Through the magnifying lens we see the bee on its honey collecting tour, and the ant in its busy, bustling community. The Lady Bird Beetle meets some grotesque neighbors while strolling down a path whereon one false step means tragedy. The cricket sings a love song while the trapdoor spider constructs a trap door. The spider disapproves the cricket's song and the cricket hurriedly departs. But he escapes one enemy only to meet another. Though larger, he is no match for the many-legged centipede. The struggle is desperate, but the centipede's poison fangs eventually find a joint in the cricket's armor, and a cheerful chirp is silenced forever." Pro- ducer Jh-sh-c Grasshopper.

Proving that the continued ex- istence of insects depends upon their abil- ity to destroy each other, we see the man- tis, one of the most formidable of insect warriors, attack and devour an unfortu- nate butterfly whose means of defense is unavailing. But, in turn, the demon man- tis IS no match for the powerful and skill- ful wasp. Again, the wasp, clever though he may be, is a weakling when when forced into combat with a spider. Even the scorpion, a creature that commands the respect of all flying and creeping in- sects, is destroyed when he meets one of his own kind. In a spectacular battle, each injects into the other a poison that results in death to both flghters."
