He cited, in this connection, a resolution of 1848, as having been framed to cover the doctrines of the Nicholson letter; and he claimed thus to have shown that the convention not only understood it, but adopted it, and made it the party creed, and that we were bound to it from that period forward. He even had that resolution of 1848 read, in order that there should be, at no future time, any question as to the principle which the party then avowed; that it should be fixed as a starting point in all the future progress of Democracy. I was surprised at the importance the Senator attached to that resolution of 1848, because it was not new; it was not framed to meet the opinions of the Nicholson letter, but came down from a period as remote as 1840; was copied into the platform of 1844, and again into that of 1848, being the expression which the condition of the country in 1840 had induced--a declaration of opinion growing out of the agitation in the two houses of Congress at that day, and the fearful strides which antislavery was making, and which Mr. Calhoun had labored to check by the declaration of constitutional truths, as set forth in his Senate resolutions of 1837-'8. That there may be no mistake on this point, and particularly as the Senator attached special importance to it, I will turn to the platform of 1840, and read from it, so that it shall be found to be-- MR. DOUGLAS. It is conceded. MR. DAVIS. The Senator concedes the fact, that the resolution of 1848 was a copy of that of 1840, and with the concession falls his argument. The platforms of 1840 and 1844 were re-affirmed in 1848; and, consequently, the resolution of '48 being identical with that of '40, was not a construction of the letter written in 1847. True to its instincts and to its practices, the Democratic party, from time to time, continued to add to their "platform" whatever was needful for action by the Government in the condition of the country. Thus, in 1844, they re-asserted the platform of 1840; and they added thereto, because of a question then pending, that-- "The re-annexation of Texas, at the earliest practicable period, is a great American measure, which the convention recommend to the cordial support of the Democracy of the Union." In 1848 they re-adopted the resolutions of 1844; and were not a little laughed at for keeping up the question of Texas after it had been annexed. In 1852 a new question had arisen; the measures of 1850 had presented, with great force to the public mind, the necessity for some expression of opinion upon the disturbing questions which the measures of 1850 had been designed to quiet. Therefore, in 1852, the party, true to its obligation to announce its principles, and to meet issues as they arise, said:
