The present work deals with the patterns of the free amino acids in several tissues of Gallula tornieri VOGT analysed by means of paper chromatography and ion-exchange resins. The tissues used were heart, stomach , muscle, brain , testis , skin , and liver. 14 amino acid was detected in heart, 11 in muscle , 15 in stomach , 9 , in brain , 10 in skin in liver , and 10 in testis.
