A photograph by Thomas Ball of Kidderminster, that appears to have been taken as a record of the effects of rickets. Rickets is a disorder of infants and growing children that was common amongst the poor in the late 19th century. It generally resulted from a poor diet deficient in vitamin D or calcium. This leads to the softening and distortion of the bones which often results in bow legs as shown here. The child portrayed here appears to be in hospital.
