Mr. Rosedeferred his notice of a motion on this subject until Thursday. His object was to diminish the evils which now resulted from the dissemination of spurious and improper Vaccine matter, by the establishment of some central Institution, from which the genuine virus should be distributed without expence. If the house should acquiesce in his motion, he should then propose to submit the management of the institution to a certain number of the College of Physicians. This was not a government measure, and he begged to be understood as having no particular partiality to any one of the present institutions more than another. His object was to give the best possible effect to the discovery of Dr. Jenner.
