 meeting that of the head, which is directed backwards, forms a 

 ridge between the ears and down the sides of the cheeks, and is 

 similarly directed on the limbs, the hair on the legs and arms 

 being directed forwards as is usual. The limbs are heavy and very 

 strong, the arms rather long, the legs short and stout.
