The identity of a pair of twins, found in the data of his former studies on the senses of taste, had already been confirmed by the author, using several substances for deciding whether they are identical or dizygotic. Through his researches in the taste of these twins to be regarded as identical, the author has reached the following results, making use of the three reagents of P. T. C., lactose and aspirin.
1. Byth of the twins tasted the bitterness of P. T. C. and even to the P. T. C. solution diluted ninety-thousand-fold they complained of equal bitterness.
2. To the lactose they had the sensation of bitterness, and to the aspirin they both seemed to have tasted something strange and told that it was rather astringent.
3. From these results of the entirely same taste reactions in the identical twins, the inheritable character of the sense of taste can be clearly inferred.
4. Thus the taste of taste reactions to some medical substances may be added to the hitherto known diagnostic methods for determining twins as identical or dizygotic.
