LIME is used in allopathic therapeutics: i. As caustic lime in combination with caustic potash as an escharotic ; it lessens the deliquescence of the potash and makes the causticity more con- trollable. 2. In the form of lime-water it is used exter- nally in combination with oil as an application to burns ; as a soothing application to intertrigo and eczema ; also internally to correct acidity of the stomach and primae vise; and in combination with milk to 'prevent vomiting in children who are fed by the bottle. It is given, with their food, to debilitated rachitic persons and to pregnant women who are supposed to suffer from a deficiency of lime. 3. As a dry powder the carbonate is applied to inflamed surfaces, and in the form of chalk mixture is administered, along with other drugs, to control diarrhoea supposed to depend on acidity. Ringer remarks that small doses, very small ones, e. g., one or two grains, act at least as well as large ones, because the diffusion power of lime 308 CALCAREA CARBONICA. is very small, and but little of it is or can be absorbed into the blood. Calcarea carbonica*' or acetica was proved by Hahnemann, and regarded by him as one of the most valuable and most widely applicable of the anti-psoric remedies. We proceed at once to consider its effects in anatomical order. Sensorium. Vertigo, especially when walking in the open air, aggravated by stooping, and most noticed in the early morning when rising or shortly after rising; accompanied by nausea and a feeling as though one would fall unconscious. The mem- ory appears to be enfeebled. As regards disposition, we notice first, indiffer- ence, with reticence and inertness ; then depression and sadness, with anxiety about the future and disposition to weep. Finally, peevishness and much nervous excitement and irritability. Despairing, hopeless of ever getting well. Anxiety, shuddering and awe as soon as evening comes near; with fear of death, tormenting those around him day and night. Fear of going crazy, or that people will observe her and suppose her to be crazy. The mind is confused, so that what is read or heard is not understood or apprehended. Heavy aching, and pressing headaches in various * Note. — In Hahnemann's them both from oyster-shells giv- provings of Calcarea carbonica ing an impure Carbonate and .and Calcarea acetica, he prepared Acetate.

The pressing pain is from within outward, and occupies only a part of the head at a time. A feeling of congestion alternately with a sen- sation of icy coldness in the head. It is peculiar to Calcarea that the head very easily becomes cold and seems affected thereby, so that headache results and the integuments of that particular part become sensitive. A muscular strain produces headache. The hairs fall out. Eyes, The pupils are sometimes dilated and sometimes contracted. Hahnemann has remarked that Calcarea is peculiarly applicable to persons whose pupils are habitually dilated. Perversions of vision are noted. Veils, feathers, shadows or black spots appear before the eyes, making vision indistinct ; it is also indistinct from straining of the body or mind, from reading, and after dinner. Also presbyopia. The lids itch and burn and especially the canthi. The lids are red and swollen ; also the conjunctiva, with much discharge of muco-pus. The pains are aching, as if grains of sand were in the eye, worse in the evening and at night; burning and itching in the eyes ; and in the lids a smarting soreness. Experience has shown the efficacy of Calcarea in scrofulous ophthalmia. (Contrast with Conium.)
