or Plaited Hair, is a disease in which the hairs are thicker than usual, and so entangled that it is impossible to separate them. It is peculiar to Poland, Lithuania, Hungary, and some neighbouring countries. Baron Larrey carefully investigated the nature of this disease when at Warsaw with the French army, and was perfectly satisfied that it is a local and factitious complaint, produced by dirt and neglect, and that it may be cured with safety. The head is to be shaved, and an ointment applied made of equal parts of sulphur ointment and pitch ointment, and the head is to be frequently washed with soap and water. Mercury, rubbed in with hair powder, is good for destroying the vermin. Internal remedies, such as Plummer's pill, or slight doses of calomel, may in some cases be necessary.
