Anyone who reads Mr. Ellis Barker's large book on Chronic' Constipation (Murray, 7s. 6d.) cannot fail to' be impressed' by the importance of the subject and the general ignorance which in spite of everything persists 1n regard- to our alimentary tract. Too many physicians still resort to drugging and injections, when diet should be the cure. As to the layman, his ignorance of the machinery of digestion and excretion is still abysmal. When knowledge of these vital subjects is more widespread, the health of the nation will be better, and we owe much gratitude to Mr. Barker and to Sir William Arbuthnot Lane for their work in this good cause.
