1. The amino acid distribution in 24-hour specimen of the urine of a patient with Wil-son's disease has been investigated by chro-matography on columns of the ion exchange resin Dowex 50. It exhibited a widespread and massive amino aciduria. The highest level of excretion in contrast with normal is reached by lysine (447mg/day), which may be elevated twentyfold. The levels of serine (454mg), threonine (291mg) and glycine (653 mg) may rise 5 to 10 fold, while alanine (181 mg), tyrosine (137mg) and histidine (704mg) occur at 2 to 4 times of the normal level.

2. Unknown ninhydrin possitive substances are found, in which the amino acids in con-jugated linkages (peptides) are probably con-tained in considerable amounts.
