Bradford Cannon Quotes

Time... is an essential requirement for effective research. An investigator may be given a palace to live in, a perfect laboratory to work in, he may be surrounded by all the conveniences money can provide; but if his time is taken from him he will remain sterile.

I heard Professor Cannon lecture last night, going partly on your account. His subject was a physiological substitute for war—which is international sports and I suppose motorcycle races—to encourage the secretion of the adrenal glands!

Since the stomach gives no obvious external sign of its workings, investigators of gastric movements have hitherto been obliged to confine their studies to pathological subjects or to animals subjected to serious operative interference. Observations made under these necessarily abnormal conditions have yielded a literature which is full of conflicting statements and uncertain results. The only sure conclusion to be drawn from this material is that when the stomach receives food, obscure peristaltic contractions are set going, which in some way churn the food to a liquid chyme and force it into the intestines. How imperfectly this describes the real workings of the stomach will appear from the following account of the actions of the organ studied by a new method. The mixing of a small quantity of subnitrate of bismuth with the food allows not only the contractions of the gastric wall, but also the movements of the gastric contents to be seen with the Röntgen rays in the uninjured animal during normal digestion.

the division. Hundreds and hundreds plunged into the fighting with their major at the head. All around James and his men, the new Lewis machine guns ratter-tattered incessantly. Cannon boomed. Tanks rolled. The air was thick with smoke from the smoke bombs thrown by the Royal Engineers into no-man’s land to screen the soldiers now entering the area. The smell of cordite, blood and human waste floated around them. But all were unaware, determined as they were to win. Defeat was not a word in their vocabulary. Many of the men were killed instantly. Two hours into the battle, James was hit in both legs by machine-gun fire. He fell, still clutching his baton. He felt the bullets hit him and the pain was intense, unbearable. He wanted to touch his legs but couldn’t sit up. He groaned, and at that moment he knew he was going to die. What a way to go, he thought … on a foreign field because of a useless war. He closed his eyes as a wave of agony gripped him. Half an hour later, it was Lieutenant Stead who found him and pulled him as far away from the fighting as he could. James was unconscious, his skin clammy. The lieutenant felt for a pulse and was relieved that the major had one, weak as it was. A few seconds later, Captain Allan Lister was on the scene to assist him, along with two stretcher-bearers and a stretcher. Together, dodging through the crowds of fighting soldiers, they carried James to the Casualty Clearing Station, a large medical tent. A team of army doctors took over at once. They could give no reassurance to the lieutenant and the captain that their major would live, despite their efforts.

homeostasis—defined by renowned physiologist Walter Bradford Cannon as “the property of a system that regulates its internal environment and tends to maintain a stable, constant condition.
