Brother and sisters. The father, a laborer, was a drunkard and feeble-minded. The mother is feeble-minded, as is her sister. In both the father's and the mother's families there are over thirty feeble- minded. CASE F.-E. L. was 25 years old when photo was taken. She has a peculiar, flat face. She is indolent, slow to obey, obstinate, passion- ate, and always dissatisfied. She can wash, dress and care for herself. She was tried in school for three years, but made very little progress. She learned to read and write a little, but her development was through her hands. She learned to be a careful laundress, washing and iron- ing very beautifully, and no lace was too fine or embroidery too intricate for her to iron. CASE G.-M. L. was 15 years old when photo was taken. His development was through his hands. He was an excellent baker, very shy and obstinate, and at times profane. He learned to read and write very imperfectly, but did excellent work out of school with the gardener. He worked in a paper mill and gave excellent service, but, tiring of it, he took to farming and is now making a respectable living. He is now a man of 42 years old, married, and has a child. CASE H.-B. L. was 30 years old when photo was taken. In three years she learned to read simple books and to write in a way, although her spelling leaves much to be desired. Her improvement was out of school. She learned to make a simple dress, to crochet lace, to embroider elaborately, and to do house and laundry work—and to do it well.
