I was googling for something when I came across this, a very interesting book.

A Handbook of Health By WOODS HUTCHINSON, A. M., M. D.
Copyright: 1911
Sometime Professor of Anatomy, University of Iowa; Professor of Comparative Pathology and Methods of Science Teaching, University of Buffalo; Lecturer, London Medical Graduates' College and University of London; and State Health Officer of Oregon. Author of "Preventable Diseases," "Conquest of Consumption," "Instinct and Health," etc.

(pp. 257)Adenoids. If colds are neglected and allowed to run on, the inflammation spreads through the nose back into the upper part of the throat, or pharynx. Here it attacks a spongy group of glands, like a third tonsil, which swells up until it almost blocks up the nose and makes you breathe {257}through your mouth. These swollen glands are called adenoids, and cause not only mouth-breathing, but deafness, loss of appetite, indigestion, headache, and a stupid, tired condition; so that children that are mouth-breathers are often two or more grades behind in school, poor students, and even stunted and undersized. You can often tell them at sight by their open mouths and vacant, stupid look. A very simple and harmless scraping operation will remove these adenoids entirely, and what a wonderful improvement the mouth-breather will make! He will often catch up two grades, and gain two inches in height and ten pounds in weight within a year."
