In the previous paper⁽¹⁾ the author discussed the lability of mixed air mass, assuming the dry adiabatic motion. The result shows that the lability of mixed air depends on its volume as well as its lapse-rat_??_.
In the present paper this problem is generalized to the case of moist adiabatic motion. In this case the labile energy becomes more pronounced, as may de expected. It is also presented one observational fact to prove the existence of convective cloud belonging to such mechanism.

Applying the spatial n-method, the author shows that capillarised ethylen blueammonium molybdate reaction of urine which indicates the concentration of dissimilation products of protein in the urine is intensified in the prefrontal region. The spatial distribution of the observed values is very similar to that of the specific gravity of the urine reported in his previous paper (Jap, Balneo-Klimatol Z., 1941). But the analysis of covariance shows that the change of the reaction might not be ascribable to that of the specific gravity.
He touches on other measure of biological variation observed day by day during one or two years. The results are summed up as follows: 1) the PH of the saliva decreases in the frontal region, 2) the improved Takata reaction shows small flocculation values in the frontal region, 3) the total qnantity of urobilin bodies in the urine decreases prefrontally, 4) the quantity of creatine exereted in the urine shows no significant change at the time of passage of depression, an, 5) the total quantity of nitrogen in the urine increases postfrontally.
All these results suggest us that there exists the remarkable bodily change ca. 12 hours before the passage of front of the straight line type near Japan which corresponds to the time of the maximum of the pressure change.

1. Applying the fact that the collection efficicncy of a thin wire is nearly equal to unity, the author has made a simple apparatus for measuring the content of the supercooled fog water, which is essentially a circular wire-netting mounted in front of a hand-anemometer.
2. Measuring the weight of the ice deposit on wire and the wind course in an adequate time interval, the water content may be easily obtamed.
3. By careful treatment of the apparatus, the error can be held less than 10%.
4. Most of the observed water content in mountain upslope fog are less than 0.5gr. per m³ at the temperature 0°C_??_-10°C.
5. The observed data have been discussed in relation, to the problem of visibiiity in fog, and as the constant of the Trabert's formula the value 2.1 has been obtained, which is about one third of the Köhler's result.
6. The effect of the intermixed ice particles on visibility appears to be rather small.
