Sigmund Engel, The Elements of Child-protection
“ In the case of the lower classes, maltreatment of children takes the form exclusively or almost exclusively of gross physical misusage. In this form the maltreatment of children is more obviously apparent, and is legally punishable; whereas more subtle but in fact worse modes of ill-usage are less easy to discover, and many of them are not legally punishable. (b) Owing to the housing conditions of the lower classes, the maltreatment of children is in their case far less likely to remain secret. ”
