  • Abstract:

    An ox, No. 7017, suffering from bovine congenital porphyrinuria (pink tooth) and excreting as much as 1•6 gm. of total pophyrins in faeces and urine per day, was still in reasonably good health at the age of 18 years. There was a slight anaemia, marked macroscopic pigmentation of the teeth and the bones, marked microscopic pigmentation of the organs, but no ill effects as a result of the porphyrinuria were shown whilst the animal was stabled during the day.
