Deep hemorrhages are palpable as hard lumps. Bleeding at an epi-physeal line may separate the epiphysis from the shaft. If an inflammationor ulceration arises at any point, fever is observed. In many cases blood-clottingis retarded. Wright maintains that there is diminished alkalinity of blood andthat scurvy is reaUy acid intoxication. Other observers dispute this. Theexamination of corpuscles and hemoglobin gives a picture identical with second-. Fig. 107.—The gums in scurvy. ary anemia. As a rule the red cells mmiber from 3,000,000 to 4,000,000 , but may fall to 1,000,000 or even less. Hemoglobin loss is more markedthan corpuscular diminution, hence the color-index is low. There is usually anincrease in leukocytes. It was observed by DeHaven, who commanded theGrinnell expedition in search of Sir John Franklin, that scurvy causes old andsoimdiy healed wounds to ulcerate. The same observation was made yearsbefore in Lord Ansons voyage. A sailor of the Centurion had been woundedfifty years before at the battle of the Boyne. He developed scurw and theold wound opened. In another case an old and soimdly united fracture gaveway and felt like a fresh break. Most cases of scurvy get well imder propertreatment, but complete recover}^ is not attained for a long time. Suddendeath is liable to occur if any exertion is made. The lightest exercise may befatal. Even moving a man while he is l
