 pression of the emotions where real distress, not the painted igment of the stage, should raise the tear, spurning of the gift of help- fitness which might be exercised for human ity, and which follows hard on to 8 noble sensibility. People would initiate the oys- ter and live in the shell of their own selfish ness preserving hard, hinty exterior, be- cause emotion is undigniied. To be surpris ed, perchance, is greater sin than to retail scandal of your neighbor. Keep a strong grip on your emotional life; it might other wise lead you into sin against good man. ners. It has been said with some truth, so old have they become, the bloom and fresh ness of childhood worn off, the artlessness and unquestioned faith well nigh gone. If the intellect and will are disciplined at the ex- pense of the sensibiEties, we have eultiva- ted monster, at least civilized heathen cold, unfeeling life that may be brilliant but heartless. The intellect should be the mo- tive power. the will the lever that holds it to it's track, but the sensibilities are the very vehicles of progress, which are to make eff fective the other powers associated with them. What was it made Thomas Guthrie so mighty in his influence over men. Why could he sway them to his will? Other men were more learned. He had been surpassed in intellectual acumen, but never in the wealth of noble sensibility, that answered to the will of men as the needle to the pole. As his intellectual and moral power was per vaded, as by an atmosphere, with true sen sibility, it became living, and men bowed be- fore it. Abe Lincoln caused a nation to weep at his death, because he was of the most ten der and helpful sensibility; and Murphy has saved his hundreds from the drunkards s fate, because his heart glows with magnetic sen sibility.
 Put the term brutishness along side of the age is it quite islander ? So stolid have we become to common woes, so placidly we of kror ahol oT1flr NxQ walk on. It is no disgrace to have a heart not doubly locked behind conventional face. Why men and women have died and made no sign, because those about them, having eyes saw not having ears heard not.

Extremes meet, and between the two is the surging mass of humanity, waiting for warm hearts and helpful hands to lift them to the vantage ground of healthful living. Let us not be ashamed, good friends, to feel 8 brothers woe; sensibility before sympathy, and sympathy before the ideal life of human ity.
 Effects Produced by Mixing White With
 CoIOred Light.
 Professor O. N. Rood in the American Journal oI
 Seience.l
 It was noticed several years ago that when white light was mixed by the method of TO- tating discs with light of an ultramarine Gar tiicial) hue, the result was not what one would naturally have expected, namely: in- stead of obtaining lighter or paler tint of violet-blue the color inclined dec!dedly to- ward violet, passing, when much white was added, into pale violet hue. Two attempts have been made to account for this curious fact Brucke supposes that the light which we call white is really to considerable ex- tent red. and that the mixture of this reddish white light with the blue causes it to change to violet. Aubert, on the other hand, follow ing suggestion of Helmholtz, reaches the conclusion that violet is really only lighter shade of ultramarine- e-blue. He starts with the assumption that we obtain our idea of blue mixed with white from the sky, which, according to him, is of greenish-blue color. We then apply, as he thinks, this idea to the case of blue which is not greenish, namely, to ultramarine-blue, and are surprised to find that the result is different.
 It will be shown in the present paper that these explanations are hardly correct, since they fail to account for the changes which, according to my experiments, are produced in other colors by an admixture of white. I prepared set of brilliantly colored circular discs which represented all the principal col ors of the spectrum and also purple; the ese discs were then successiyely combined in va 1lOuS H16u t WulGS QlSC duQ Gu6 effects of rapid rotation noted, smaller du- plicate colored disc combined with white be- ing used for comparison. Under these cir cumstances it was found that the addition of white produced the changes indicated in the following table:
 vermilion became somewhat purplish
 Orange became more red
 Yellow became more orange.
 Greenish yellow unchanged.
 YeLowish green became more green.
 Green became more blue-green-
 Cyrn-blue became less greenish, more bluish
 Ultramarine (artificiaD became more violet.
 Purple became less red, more violet.
 Exactly these same effects can be produced by mixing violet with the above mentioned eolors These experiments serve to explain the singular circumstance that when compile mentary colors are produced by the aid of polarized light, it is difficult or impossible to obtain a red which is entirely free from a purplish hue, a quantity of white light being always necessarily mingled with the colored light In the of the red, orange, yell low, ultramarine, and purple discs, I succeed ed in measuring the amount of violet light which different proportions of the white disc, virtually added to the mixture, and found that it Is not directly proportional to the amount of white light added, but increased in 0 slower ratio, which at present has not been accurately determined.
 For the explanation of the above mention ed phenomena, Brucke's suggestion that white light contains certain amount of un- neutralized red light is evidently inapplica- ble, since the effects are such would be produced by adding quantity not of red but of violet light, and for the present I am not disposed to assume that white light con- tains an excess of violet light. The e1plana- tion offered by Aubert does not undertake to account for the changes produced in col ors other than ultramarine, and even in this case seems to me arbitrary; neither have succeeded in framing any explanation in &C., cordance with the theory of Young and Helmholtz which seems plausible.
