This report is a well printed booklet of over 100 pages and is profusely illustrated, showing all sides of colony life. A special section is devoted to scientific papers and reports made up of articles contributed by members of the medical staff. The amount of surgical work done at Sonyea is evidently considerable as anesthetics were given 172 times during the year. The book describes also a modern hydrotherapeutic plant that has been installed and is proving a valuable feature in the treatment of certain types of epilepsy. Much information of a general character is given. The fact that the colony embraces 1,895 acres of land, with 76 houses and a population of about 1,300; the net per capita cost of keeping patients and a general description of life in the colony, all go to make instructive and interesting reading.
