Salisbury, early in April last, a paper containing a de scription, with figures, of certain algoid growths, which he had discovered in persons affected with variola, vaccinia, and typhoid fever, and which he considers to be the causes of those diseases. The paper, he writes us, was prepared about a year since, and was shown at that time to Dr. J 03. G. Richardson, who, in a letter to us, con firms that statement.
