Abstract
Using certain inbeed strains of mice (SM, DDd, and NA- II strain) and mixed bleed strain, F1, (SM x DDd), the author studied the sense of taste against PTC (Phenyl-thiocarbanlide), saccharine, acetic acid, and NaC1, and got the following results.
1. In the case of discrimination test against water and test solution, NA- IL strain was most sensitive against every test solutions, and mixed bleed strain was far more sensitive than parent strains.
2. In the case of discrimination test among test solutions, same tendency was observed.
3. The author could not find any correlations between the threshold of discrimination and the average of water (or solution) intake.
4. In every experiments, the mouse hesitated to drink PTC solution at very low concentrations.
