Chlorosis

(klo-rō'sīs,) (or the GREEN SICKNESS.) [From Gr. chloros, green.] (Med.) The old name of the morbid diminution of the red globules of the blood, now called anæmia; and still applied to that disease when it occurs in females at or near the age of puberty, without being the result of the ordinary causes of anemia, such as hemorrhages from wounds, deficiency in alimentary supplies, . It appears to be in some way connected with the evolution of the reproductive functions. In some cases it may be accounted for by the derangement of the a imilative functions of this period. In these cases the appetite is poor, the digestion disturbed, and there is apt to be a craving for indigestible, in nutritive substances, such as chalk, slate, coal, . C. is removed by means of plenty of open-air exercise, stimulating food, tonics, sea-water baths, . (Bot.) A disease consisting in a pallid condition of a plant, in which the ti ues are weak and unable to contend against severe changes, and the cells are more or le destitute of chlorophyll. It is distinct from etiolation or blanching, because it may exist in plants exposed to direct light on a south border, but is often produced or aggravated by cold, un genial weather and bad drainage. The best culture will not always restore such plants to health. The most promising remedy is watering them with a very weak solution of sulphate of iron. [s. 181]
