    circulation, wLicli takes place during sleep, and is paralleled by the morning depression in melancholia and debility. I have met with this train cf symptoms at the two extremes of high and low pn^ssure. When theie is high pressure it is that the general re- sistance in the ]3eriphery has overtaxed the powers of the heart, so that the whole circulation is sluggish, and the languid How is most easily brought to a stand- still where the difficulties are greatest. Usually the symptoms come on very gradually, but I have known their onset to Ije determined by the occurrence of acute dilatation of the heart, and have seen cases in com- paratively young men suffering from high arterial tension in which paraplegia came on almost suddenly after prolonged over-work. The patient may have previously suffered from other ill effects of high arterial tension. When the tension is low and the heart weak, no explanation of the impeded circulation is needed.
