A sister or double line always shows an increase of the power of the original line, therefore a sister line of the Heart which is a very rare occurrence indeed shows great tenderness in love, susceptibility to friendship, and a strengthening of the health so far as the circulation is concerned; and indicates the pos­session of much nervous force. This is more especially the case where the original Heart line is chained, weak, or much crossed, at the same time it is probable that sorrow will be the result of a love so deep and tender, and capable of such untiring devotion.
