Kent comments upon this condition in his ‘Lectures’:
‘It is a strange thing to see a bright little girl of 8 or 9 years taking on sadness, melancholy, and commencing to talk about the future world, and the angels, and that she wants to die and go there, and she is sad, and wants to read the Bible all day. That is a strange thing; and yet Calcarea has cured that. Ars. has cured that state, and also Lachesis. They are a little inclined to be precocious, and they have attended the Sunday-school and they have taken too seriously the things they have learned. ’
Calcarea children usually have to be quite ill before they lose their ability to concentrate and their capacity for mental work. They are generally quite brilliant and do well in school; their performance is typically above average. They tend to be quite determined in their studies, work hard and are well organised. Their ambition and competitiveness causes them to push themselves too hard, to overexert themselves to the point that their mental stamina is lost and their capacity for concentration is undermined. At this point they may become restless and want to leave school. Overwork is well known to be one of the precipitating causes of Calcarea carbonica states of pathology.
After puberty, at the ages of 14, 15, or 16, Calcarea children begin to develop a fear of high places and vertigo from heights. They may not even be able to tolerate watching someone else on a height without feeling excited and fearful. This fear is so strong that they can have dreams and nightmares about high places. Prior to this age it is unusual to encounter this symptom, so frequent in adults. Fear of heights is a strong key-note in both Calcarea and Sulphur.
Pulsatilla children can often be confused with Calcarea children. Puls, may enter a similar state of inquiry towards religion and the after life. Their constitutions possess similarities; the physiques can be the same, and Puls, can have a desire for soft-boiled eggs (It should be added to the Repertory for this desire.) Puls, children, however, are much softer emotionally and more prone to cry easily.
