On the other hand, in the cases of general arterio-sclerosiswith marked hypertension, chronic Brights cannot be elimi-nated .without care. The combination is frequent, and givesthe highest pressures usually met with. A recent case, forinstance, had systolic 240 mm., diastolic 160 mm.

Chart from male, aged seventy, with marked arterio-sclerosis, general, retinal, andcerebral; cardiac hypertrophy, and slight chronic nephritis; during an attack of acutebronchitis. Note the moderate hypertension and moderate increase of pulse-pressure. 188 BLOOD-PRESSURE IN INTERNAL DISEASES rule with evident arterial thickening, but sometimes must be considered as having, with or without thechanges in the larger arteries, a permanent augmentation ofthe peripheral resistance in the smaller arteries and arterioles,especially in the splanchnic circulation, or a general narrowingof the larger visceral arteries.
