Amphibians
Edited and introduced by Maxwell Knight
Amphibians are born with aqua-lungs, and at this season they are awakening from their winter hibernations-which in many cases have been spent on the land -and are taking to the water.
R. MAXWELL SAVAGE shows how the spring emergence and spawning of the common frog are stimulated by changes in the weather, and discusses the voices of the common, marsh, and edible frogs
HUMPHREY MOORE, a Dorset school-master, describes how a group of boys helped him to investigate the spring migration of the common toad
JUDY AUSTIN explains why newts are so little seen during their winter on land, and describes the courtship which takes place on their return to the water
