We have not clear evidence of the effect of baryta on this system, but it is presumed to exert some absorptive "deob-struent" power on inflamed or hardened lymphatic glands. Small doses increase the secretion of urine and of perspiration (Waring).

Synergists

Lime and other alkaline earths. The chloride of barium has some analogies with corrosive sublimate.

Incompatibles

All sulphates are chemically incompatible with barium salts, forming insoluble compounds. The sulphates of soda and magnesia have been used as antidotes in cases of poisoning (Walsh), also white of egg and sugared wine (Perondi: Bulletin de Therapeu-tique, t. x.).
