I and the conclusion is, that no such Globe exists. I know that shall disappoint many of you to-night by this assertion, but the facts are, that we sweep out to the Double Stars, to the Triple Stars, to the Quadruple Stars, to the Quintuple and to the Sextuple Stars, and we find no such point about which they are moving. The next question to be presented is this: Is there no Centre of Gravity, about which all the mighty host of Suns and Stars, and Comets circulate, obedient to its laws? I answer that there is, and it was to the solution of this problem, that MÆDLER gave the energies of his mighty intellect. At this stage of the lecture, the Reporter, who was suffering from an affection of the eyes, found it absolutely necessary to suspend writing for some five minutes. The following portion of the lecture enclosed in brackets is given from memory. [After long years of labor, after he had almost exhausted the capabilities of analysis, after bringing to bear upon the problem all the mighty influences of science and art, after ranging from point to point in the heavens, which he was compelled successively to abandon, he turned his attention to the examination of the beautiful group of Stars called the Pleiades. After watching their movements, until he had computed the rates of motion of the principal stars in this group, and the direction in which they were journeying, he found to his great delight that they fulfilled all the conditions of the problem, and the grand result was attained. The truth comes irresistibly upon the mind, that there is the centre, and that is the point about which all the bright hosts of heaven are sweeping, in periods which actually stun the human mind. MEDLER has already computed the periodic time of our own Sun, which gives this astonishing result. It takes our Sun two hundred and eighteen millions of years to complete its stupendous cycle.] Here I find that I must close. I know that I have exhausted the patience of the audience, but if you will allow me five minutes time, I will answer a request that has been made by several gentlemen of this city, who are deeply interested in the wonderful science of which I have been treating. I have been requested to state the condition of the Observatory in Cincinnati, with what degree of permanency in the way of support it enjoys. I commenced this enterprise about five years since. I began it at a time when I was much depressed. It was said that we could not raise seven thousand five hundred dollars in as many years-it was subscribed in as many hours. It was said we could never collect it: it was collected, and ten thousand dollars appropriated for an instrument, the second in the world. It was said we could never get a site to build upon: a gentleman in Cincinnati gave us one of the most beautiful sites upon the wide Earth. It was said we never could build the Observatory: the mechanics and artificers came together and said, we will help you to build that house. One supplies glass for the windows-one planes the boards for the floors-another puts them down, and in that way the building was reared-and when the roof was on not a dollar's indebtedness had been incurred. At this juncture it was found necessary that the building should be completed, and the instrument in its place at a certain time specified in the bond, or we would forfeit the whole establishment. Rather than suffer this, I determined to throw all the little means I possessed into the fund. The building was finished-the bond was saved-but unfortunately I had contracted a debt of four thousand dollars. I had no means to meet this with. I determined to try what I could do in other cities. I went to Bos ton. The first night I had only one hundred auditors. On the following night my house was filled, and on my return home, such was the effect produced, that the Society was called together, and I put the question, "Shall I go elsewhere to raise money to extricate me from my present embarrassment?" They rose in their places: Put me down for a hundred dollars, said one-put me down for a thousand dollars, said anotherand the amount was soon raised and the debt liquidated. In taking leave of this audience, permit me to say one word. I came here without expectations. You have borne with me patiently. For your great kindness I am deeply indebted, and shall ever remember my visit to you with the highest gratification. One word more. I know that there is an interest awakened in this subject, which will never be permitted to die. The whole country looks to your city as the metropolis of wealth and learning, and it expects you to take the lead in all matters of art and science. Will you not then concentrate your efforts at once, and before I shall again place my feet in your city, let there tower from its midst, a Temple of Science, which shall eclipse the great Observatory at Pulkova itself? THE PASSAGE OF THE RED SEA. THE cloudy pillars ceased to move, and Israel emcamped before Pihahiroth. Silence reigned, save as was heard the sound of rippling waters, in plaintive cadence, as if they sang the dirge of the departing sun. Night drew on, and Abraham's numerous race prepared for rest. Visions of that bright land to which they were bound flitted before them, and in imagination, already they wandered over its hills and plains. Memory recalled the oft-repeated promise of Jehovah to their fathers before them, and their hearts were full of praise and gratitude to Him who had ever preserved and appeared in their behalf. But hark, a crashing sound is heard. What is it? Has the deep broken loose, and does it come to bury them in a watery grave? Ah no. The clash of arms, and tumultuous sounds of battle hosts are heard. 'Tis Pharaoh. His hardened heart has forgotten those fearful visitations of an offended God, and repenting that he let Israel go; with speed he hastes to overtake them, firm in the hope of conquering them, and leading them back as trophies of his victory. Who is Israel, and who their God, that I cannot conquer them? They shall feel the might of Pharaoh's hosts. I will increase their burdens, and grind them down with ten-fold vengeance, e'en as their God has visited me. And in imagination he sees them the victims of his wrath. Mistaken prince! How little dost thou dream, that thine hour of retribution is nigh. Thou hast looked upon thy home for the last time. No more wilt thou behold thy loved ones, nor listen to the music of their voice. Ere another day shall close upon thee, death will have set his seal upon thy brow, and the deep shall be thy burial place. No monument shall grace thy tomb, nought mark thy resting place; the billows shall play over thee, unconscious of thy mournful fate. And now murmurings are heard in the camp of Israel. Before them is the sea, behind, their foes, and mountains on either side. Death seems inevitable. Unbelief possesses their hearts, and they exclaim: Were there no graves in Egypt, that thou hast brought us here to die? O Israel, where now thy faith in him, who has watched over thee, and oft-times delivered thee. Murmur no longer, "Great deliverance, |
