Naumann studied 100 cases, from which all who had fever,arterio-sclerosis, heart lesions, pleural adhesions, or albumin orsugar in the urine, were carefully excluded.

As to incidence with the extent of the pulmonary lesion, of the 69 patients with over 130 mm., there were, in 1st stage (Turban), 28, in 2d 22, in 3d 19.

Naimaann believesthat arterial tension is valuable in prognosis, as showing tosome extent the constitutional disturbance, which is unques-tionably a better guide to the future than the local signs.
