In 1905 she founded the Théâtre Réjane. She died in 1920.
RELAPSING FEVER (also known as FAMINE FEVER and SEVEN-DAY FEVER), one of the three great species of continued fever, the two others being typhus and typhoid. It was first definitely discriminated from these diseases by Dr. Henderson of Edinburgh and other Scotch physicians about 1842. During the 19th century it was met with in Ireland, Scotland, England, in central and eastern Europe, the countries surrounding the Levant, north Africa, India, China, and, though never extensively, in North America. Relapsing fever usually begins suddenly with rigors, a sense of chilliness, and frontal headache.
There is severe aching pain in the joints and muscles, and great sleeplessness; but delirium, if present at all, usually comes on only toward the end of the first week.
After the above-described symptoris have lasted for a period varying from five to eight days, generally on the seventh day a sudden change takes place. This crisis commences with a copious perspiration, which is followed by a rapid falling of the pulse and temperature to or below the normal, and the patient appears nearly well. But from the fifth to the eighth day of this seeming convalescence a sudden relapse occurs, and all the primary symptoms return; these often run a rather shorter course than before, and again terminate in sweating and in a second convalescence, which is in most times, however, occurs three or even cases permanent. The relapse somefour times. Death is a rare termination of relapsing fever; except enlargement of the spleen. One form of the disease, however, is much more severe,`! and very often fatal. It was originally described as a distinct disease under the ized by more marked implication of the name of bilious typhoid, and is charactercomplete development of the crisis and digestive organs, by the constant presence of jaundice, and by absence or incomplete development of the crisis and proper. Relapsing fever is generally be really identical with relapsing fever proper. Relapsing fever is generally met with among those living under uning from insufficient nourishment (hence cially apt to attack a population suffermet with among the upper classes, or the name famine fever), and is seldom met with among the upper classes, or among Europeans residing in the tropics, unless they are brought closely in contact with the sick.

It is connected primarily with the contrast between the absolute and the relative, or the noumenon and phediscussions as to the relation of knowldiscussions as to the relation of knowledge to reality. In its modern form the doctrine has obtained currency chiefly through the speculations of Kant, Hamilton, and Herbert Spencer. Knowledge tion between the knower and the object known. Hence it is argued that the obknown. Hence it is argued that the obwhich it is brought; merely by becoming which it is brought; merely by becoming an object the thing as it is in itself undergoes a change or accommodation. Our knowledge therefore can never yield us the reality of things-the noumenon or thing-in-itself-but only the phenomenon, the thing as it appears to us. as it is otherwise expressed, in being known the object must conform to the nature of the knowing faculty; the mental constitution or organization of the knower; we cannot, therefore, conclude, says Hamilton, that the properties of existence are known "in their native purity and without addition or modification from our organs of sense, or our capacities of intelligence.' general conclusion is: "Of things absoe. " Hamilton's general conclusion is: "Of things absoor be they internal, we know nothing, or or be they internal, we know nothing, or become aware of their incomprehensible existence only as this is indirectly or accidentally revealed to us, through certain qualities related to our knowledge. All we know is therefore faculties of phenomenal, phenomenal of the un- knowledge. All we know is therefore Or, RELEASE known." This is adopted by Spencer, and made the basis of his theory of knowledge, or rather of what Ferrier would have called his agnoiology, his doctrine of our necessary ignorance: "The reality e is, and must ever be, unknown." In Kant a similar doctrine is associated existing behind all appearances forms of space and time; but it is also perception can give us "only the relaperception can give us "only the relation of an object to the subject, not the ject in itself." The empirical schools, which resolve our knowledge into iming to the laws of association, likewise ing to the laws of association, likewise accept in its widest sense, as J. S. Mill points out, the doctrine of "the entire inaccessibility to our faculties of any other knowledge of things than that of the impressions which they produce in skeptical idealism which denies, or leaves much as they in many cases profess a our mental consciousness."
