Occasionally there is a rise of temperature, butit is probably due to some complication. (See Plate XVIII.—B, Fig. 1.) The cause of chlorosis has not been determined satisfactorily. Vir-chow has established the existence of congenital narrowing of the blood-vessels. Sir Andrew Clark thinks it is due to the absorption of poisonousmatter from the intestines ; the great benefit that follows saline purgativesin many cases indicates that fecal toxaemia is a factor in these Pernicious Ansemia. 1.
