Our only excuse for adding to the already overburdened literature of the pathology of the lymphatic glands is the belief that there is still need for long and careful observation on cases of any disease of this system, but more especially of the group originally designated by the term ``pseudoleucemia.'' Our knowledge of this group has reached the point where one case, studied carefully by the clinician in conjunction with the pathologist, is of more value than a large series of cases drawn from the average medical, surgical and pathological records, which are not complete in all the necessary details.1
