Even had it been otherwise, the defect just alluded to would have rendered it useless for our present purposes, until a prior Classification had first been made, exhibiting the radical difference between the various domains, which are all indiscriminately grouped under the name of _Science_. After such a Classification, based on the nature of _proof_ as involved in Method, the Principle which guided Comte in the establishment of the Hierarchy of the Sciences will enable us, in a concluding paper, to estimate with proximate certainty the character of a possible Science of History, and to ascertain how far the labors of Mr. Buckle and Professor Draper have aided toward the creation of such a Science. DIARY OF FRANCES KRASINSKA; OR, LIFE IN POLAND DURING THE EIGHTEENTH CENTURY. Friday, _April 10th._ Easter week is over, and I am really sorry; I had found happiness in repose, and already have care and disquiet won their way into my heart and my mind.... How many sins I have committed! Poor humanity! poor nature, so frail and weak! Notwithstanding my promises and the resolutions which I fancied so strong, I yield to the least temptation. For example, and it is indeed incredible, but a fact, that on Holy Thursday, the very day after my confession, I sinned, and sinned through pride. I should have worn black when I went to be present at the court ceremony, but I could not resist the seduction of a beautiful costume. Just as I was beginning my preparations, the Princess Lubomirska entered my room, accompanied by her maids, who brought me a charming dress of white velvet, with a long train, and trimmed with white roses; the headdress consisted of a garland of white roses, and a long white blonde veil. The taste and richness of this costume surpasses description! How could I resist the happiness of seeing myself so becomingly attired! I asked the princess why she required me to wear so brilliant a costume to church; she replied that on Holy Thursday it was customary after the service to go into the great hall of the castle, where the king would wash the feet of twelve old men, in commemoration of the humility of our Saviour, and that he would also wait upon them at table. During this pious and edifying ceremony, a young girl belonging to one of the noblest families must make a collection for the poor; the king himself names the lady, and this year he was pleased to honor me by his selection; he at the same time announced that the results of my efforts should be given to the hospital for the poor under the Abbe Baudoin's charge.
