Without in the least minimizing this need, I want to point out that the strain on institutions could be greatly relieved if more and better day centres could be provided for children classed as " ineducable A number of occupation centres have been set UP during the l...

For attribute data with (very) low rates of defectives, attractive control charts can be based on the maximum of subsequent groups of r failure times, for some suitable r ≥ 1, like r = 5. Such charts combine good performance with often highly needed robustness, as they allow a nonparametric adaptation already for Phase I samples of ordinary size. In the present paper we address the problem of e...

I HOPE the meeting will forgive me if I deal entirely with local authority services for the mentally ill. It seems that whereas in meeting the needs of mental defectives the local authorities have considerable experience and themselves know where they wish to go, local authority work for the mentally ill, though more advanced in some areas than in others, is in a state of creative chaos, with m...

Darenth Park is just as different from the average journalists' or lay person's ideas of a mental hospital as are the obverse and reverse of any other golden coin of the realm. It is proud o...

A series of brains chosen from the Stoke Park Collection formed a demonstration designed to show:? 1. The rate of growth of the normal human brain during the first few months and years of life. 2. The complete failure of the defective brain to achieve such normal growth, and 3. The additional occurrence amongst defectives of cerebral malformations of pre-natal origin and peculiarly gross kind. ...
