In eleven of 201 cases, lateralcurvature was present in either the father or mother of thepatient; and in seventeen others a brother or sister of the patientwas deformed in a similar manner. Occupation.—As occupation may induce deformity in theadult, and one looks naturally to occupation as a factor in thecausation of lateral curvature in childhood. Occupation in thisclass implies school, and it is well known that fatigue duringschool hours may induce improper postures, especially if thechair is unsuitable or uncomfortable. The influence of habitualposture is indicated in the statistics of lateral curvature amongschool-children recorded by Scholder, Werth, and Combe,^ the ^Bull. Medicale, June 15. 1901.
