To its social life, of any class whatever, introductions are the only key. To its political movements the ordinary tourist has little access beyond what the newspapers give, and that he may have at home. To be an eye-witness of momentous events or of the circumstances that shape a nation’s destinies is hardly to be hoped. Her history lies all about in monuments, and ruins, and palaces, and institutions, volumes in changeless stone. Her general conditions of prosperity, commercial and other, may be guessed from what one sees, and, reading backward from effect to cause, the thoughtful observer may determine something of individual and national character. Something comes to him by intuition, something by observation, and slowly, by ways he knows and ways he knows not, he feels that he is coming to a knowledge of England, of English people, and English life. London of all places seems the spot to bide. He haunts her galleries and walks her streets, and dreams in her abbey, and sits in her churches, and finds he is claiming her history as his own. If Americans must live anywhere out of America, London, with its teeming varied interests, its thousand worlds in one, is the place for him to live. What sights he will see there, what things he will do there, everybody knows. Let art, or literature, or commerce, or religion, or science be his hobby, he will find companions enough and to spare. There is room for everything in London, notwithstanding it is the most crowded place under the sun; room even for us who, while jogging along together, yet have each cast our nets in separate streams. What we shall gather, who can tell?

If the particles forming the envelopes are minute flat bodies, and if anything in the circumstances under which these particles are driven off into the tail causes them to always so arrange themselves that the planes in which they severally lie pass through the axis of the tail (which, if the tail is an electrical phenomenon might very well happen) then we should find the region behind the nucleus very dark, or almost black, for the particles in the direction of the line of sight then would be turned edgewise toward us, whereas those on either side or in the prolongation of the envelopes would turn their faces toward the observer. OUR CHILDREN. By GENEVIEVE IRONS. _A Hymn for Teachers._ O Lord our God we thank thee For little children dear, Gleams of thy mercy’s rainbow Which thou dost send us here; O! teach us how to make them What thou wouldst have them be, Teach us to train our children For heaven and for thee.
