SOME REMARKS ON BACKWARD CHILDREN. 
(Abstract.) 
By Dr. Raoul Dupuy. 
When we speak of a backward child, we mean any subject which is arrested 
or retarded more or less completely in its bodily, psychical, and sensorial 
evolution, in consequence of congenital and acquired lesions, or simply in con­ 
sequence of physiological troubles, which concern, either at the same or a 
different time, the brain and the glands of internal secretion (the thyroid, the 
hypophysis, the suprarenals, and the genital glands). The cerebral lesions, 
practically incurable in the present state of science, produce “atropic back­ 
wardness ” the functional troubles of the brain, or those caused by the glands 
of internal secretion, which can be modified by “ combined organotherapy ” 
produce dystrophic backwardness. We also, however, find mixed types, half 
of the one and half of the other, which are similarly susceptible of improve­ 
ment. The number, and above all the variety of the types of dystrophic 
backwardness, makes a general classification of them impossible. The study 
of their bodily, psychical and sensorial anomalies proves that in most of the 
manifestations of backwardness and immaturity, these children present 
perversions of evolution which have a common bearing on the development of 
body, mind and spirit Although apparently different from one another, these 
backward persons, whether the mischief be corporal, psychical or sensorial, 
show pathological peculiarities, which prove that the cause of their various 
dystrophies have a similar origin, and that they often arise from defective 
function of the sympathic system which appears to be brought into action by 
the internal glands. The backward children consist of intoxicated, under­ 
grown or anaemic persons, who, besides, suffer from retention of substances,
