In medicine, that great and most useful branch of physics, our countrymen have been most distinguished. From the days of the great philosopher, physician, patriot, and statesman, Benjamin Rush, down to the present period, our country has been unsurpassed in this branch; but I have not time even to give an outline of the eminent Americans, whose improvements and discoveries in medicine have contributed so much to elevate the character of our country, and advance the comfort and happiness of man. Rush, one of the founders of this branch in America, was one of the signers of our Declaration of Independence, and his school of medicine was as independent and national as his course in our Revolutionary struggle. Statistics are chiefly concerned, as furnishing the facts connected with government and political economy, but they are also ancillary to physics. The statistical work of Mr. Archibald Russell, of New York, which immediately preceded the last census, contained many valuable suggestions, some of which were adopted by Congress; and had more been incorporated into the law, the census would have been much more complete and satisfactory. The recent statistical work of Mr. George Tucker, of Virginia, on the census of 1840, is distinguished by great talent and research, and is invaluable to the scholar, the philosopher, the statesman, and philanthropist.

Holy Father, Thou this day Dost a cross upon me lay. If I tremble as I lift, First, and feel Thine awful gift, Let me tremble not for pain, But lest I may lose the gain Which thereby my soul should bless, Through mine own unworthiness. Let me, drawing deeper breath, Stand more firmly, lest beneath Thy load I sink, and slavishly In the dust it crusheth me. Bearing this, so may I strength Gather to receive at length In turn eternal glory's great And far more exceeding weight. No, I am not crushed. I stand. But again Thy helping hand Reach to me, my pitying Sire: I would bear my burden higher, Bear it up so near to Thee, That Thou shouldst bear it still with me. He, upon whose careless head Never any load is laid, With an earthward eye doth oft Stoop and lounge too slothfully: Burdened heads are held aloft With a nobler dignity.
