sions by analytic methods involves no difficulties beyond those found in analytic geometry of three dimensioned space except merely the increased complexity of the equations. It is evident, too. that such investigations may be carried higher than space of four dimensions, and even made general for n dimensions. As to the real existence of the fourth dimension the preceding discussion offers little evidence: that a thing is logically possible is no argument for its actual existence. There are. however, a number of facts that point in that direction. ()ne of the most striking is the presence of bilateral symmetry in animal forms alluded to above. If this symmetry is due in any way to rotation alxmt a plane, then it is only the minutest particles which partake of that motion. This may be intimately connected with the question as to why there is only a finite number of kinds of matter. This also is adequately explained on the theory of a fourth dimension: all molecules then rest on the same clastic film which synchronizes their vibrations. Most of us accept the elastic ether theory of the transmission of energy through space; but if bodies in our space have a small thickness in the fourth dimension, and if our space rests on a homogeneous elastic film in that dimension, the law of inverse squares for variation in radiant energy will follow as logically and in as believable a way as from the ether theory. There are also astronomical facts which tend to show that matter in our space is not distributed evenly, but is found in lessening quantities in the outlying regions. If this be true, a constant positive curvature of space in the fourth dimension can account for it. space then being unbounded, but not infinite. A Contagious Disease, Perhaps less is known of this disease than any other with which the medical profession has dealt. It was first discovered in Colleges and High Schools in 1720 before the existence of Xormal schools and is still prevalent. When the first Normal school had operated for about two years symptoms of it were discovered there. Since that time this disease has gained a very firm grasp on all institutions of learning. All the Normal schools have had to deal more or less with this dreaded evil, and now we have discovered well marked symptoms of it getting a rapid hold on the students of our school. It is most prevalent among boys and several of the lx ys have become the prey of this ailment. The football team was attacked by its germs and the basket ball team suffered heavily. About forty per cent, of the first team succumbing. 'Pile second teams were more fortunate. About Thanksgiving several inhabitants of the dormitory were stricken. Quite a few of the girls are now suffering with this terrible malady. Scientists and professors have exerted all their energies in fruitless results trying to co| ‘ with it. The first symptoms are noticed by the patients peculiar attitude towards fellow-students. As the disease gains in strength the patient lalxirs under the impression that he is the elite of the school. Usually the disease continues to grow until the sufferer is relieved by the president of the school, who has been successful in finding a partial cure. At a recent consultation of University professors a conclusion was arrived at in which they termed it swell-head.” PAOK THIRTKKN

of space can he enclosed by surfaces is an illusion due to our sense limitations. Any closed space, as a room, is “open on the side of the fourth dimension and an entrance or exit may lx made readily if that direction is taken. This higher being could see no difficulty in causing two symmetrical spherical triangles or two symmetrical solids to coincide, the possibility of rotation about a plane, or of turning over in the fourth dimension being as readily perceived by him as rotation alxnit a line is by us. or rotation about a point by a two dimensioned being. .Vow as the inhabitants of a two dimensioned world may justly argue a third dimension from symmetry in plane figures, so may we argue a fourth dimension from the existence of symmetry in solids: and as we can prcccivc the former directly. so would a four dimensioned being prcccivc the latter directly. And further, since in nature only living forms exhibit symmetry about a plane, we may argue a connection between life and a fourth dimension. Again, if our space is not “plane.” but has a curvature, say a positive constant one. then it may not be infinite in extent but finite though unbounded. This curvature might he discovered by measuring the angles of very large triangles, c. g. those whose vertices arc fixed stars, and noting a spherical excess. Indeed an assertion of such an excess has been made, but errors of measurement doubtless account for it. On the other hand, failure to detect an excess may be due to the immensity of our space and the comparatively small size of the triangles used. If this four dimensioned being should pass a solid of his space through our space, we could see the three dimensions which were in our space, but not the fourth. As it passed through our space from the fourth direction it would appear l crhaps like a changing solid, increasing or decreasing in size, coming into view from nowhere and disappearing as mysteriously. Or it might seem a solid appearing suddenly and retaining a permanent form for a time and then disappearing. Perhaps living forms answer this description. GKOMKTRY OF FOt’R DIMENSIONKl Sl'ACK. While we cannot gain a definite concept of space of four dimensions it is possible to work out by analytic methods a great many facts about it. Just as a point in a plane can be determined by two coordinates referred to two axes intersecting at right angles, and as any point in our space can lx? fixed by three coordinates referred to three axes, the third being at right angles to both the other two. so any point in four dimensioned space can be determined by four coordinates, referred to four axes, the fourth being at right angles to each of the other three. Further, an equation in two variables represents a line in a plane; and if the line is a closed curve it bounds a |x rtion of the plane, and thus serves, in two dimensioned space, to determine completely a two dimensioned “solid.” An equation in three variables represents a surface in three dimensioned space; and if the surface is a closed surface (e. g. the surface of a sphere or ellipsoid), it completely determines a three dimensioned solid. Then an equation in four variables represents a surface in four dimensioned space, which, if it is of proper curvature will determine completely a four dimensioned solid. In fact the investigation of space of four dimen- I'AGH TWELVE
