Leukocytosis. What is leukocytosis ? Leukocytosis is a condition of the blood in which, withoutalteration in the number of red corpuscles, without enlargementof the spleen, of the liver or of the lymphatic glands, the num-ber of white corpuscles undergoes an intermittent or transitoryincrease. It may be physiologic^ as when it occurs after meals,or it may be a transitional stage of leukemia or pseudo-leukemia. Leukemia. What is leukemia or leukocythemia ?

Fig. Appearance of the blood in leukemia. (Funke.) Three varieties of leukemia are recognized: Uenal, lyynphaticand raedullary, as the spleen and liver, the lymphatic system,and the medulla of bones, respectively, are involved. Early in the course of the disease, the spleen becomes con-spicuously enlarged ; sometimes friction-fremitus may be de-tected on palpation, and a blowing murmur on auscultation ;ascites may develop. In the further course of the disease, theliver and the lymphatic glands may also become enlarged ; thebones may be painful and tender ; changes in the kidneys and inthe intestinal glands are sometimes noted. The number of ivhite corpuscles in the blood is increasedbeyond 10,000 to the cubic millimeter, sometimes in extraordi-nary degree. The number of red cells and the quantity ofliemo-globin are diminished. Through increase in the number of thewhite, a
