The Endocrine Function of Iodine

such a philosophy of life that we shall live long, happy, prosperous lives, ready to attack willingly the problems of the day and not to shirk our many responsibilities. It may suggest that each of us has a mission, no matter how great or small, and that there is a certain responsibility for our individual life which is loaned to us at birth, taken away at death, and for which we should feel somewhat accountable during our existence." It is unfortunate that the general biological literature, ostensibly at the college level, should be cluttered with a range of misinformation which this poorly written book contains. J. s. NICHOLAS.
