Excerpt from Heart, 1909-1910, Vol. 1: A Journal for the the Study of Circulation The Journal requires communications, containing, above all, original and carefully ascertained facts, and conclusions consonant with such facts and previous observations. By a record of fact and the statement of new principles progress will be ensured. The advances of recent years are largely indebted to Gaskell and his work for their initiation, and this Journal heartily appreciates the message he sends it as it takes the first step on its course.
