Comparative studies on top note (the first impression of scent) of eleven kinds of black tea sold on the market were carried out. Aroma patterns were obtained by cryogenic vapor phase chromatography and acceptability was judged by organoleptic test. Correlation between prices and acceptability was also discussed. Comparing aroma patterns with acceptability of eleven kinds of black tea sold on the market, it was con cluded that linalool, n-pentanol, iso-pentanol, acetaldehyde, dimethylsulfide and ethylacetate contributed to the acceptable top note of black tea. It also was made clear that flavor-enriched black tea was easily recognized by cryogenic vapor phase chromatography because its aroma pattern was distinctively different from that of no-flavor-enriched black tea. The prices do not always guarantee the acceptability of black tea.

A mixture of egg yolks and hot water was beaten with a “Mixmaster of Sunbeam”. Other substances were added into the mixture in some experiments. Effects of the consistency of egg yolk, the temperature of water and added substances on the formation and stability of the egg yolk foam were studied. The effect of the egg yolk foam on the sponge cake was also studied. The following results were obtained.
1. When much water is added to egg yolks, more foam is made, but the stability of foam decreases.
2. When the temperature of water added to egg yolks is high, the formation of foam is accelerated, and its stability increases.
3. One per cent of tartaric acid in the mixture of egg yolks and water retards the formation of foam, but none of oil, sugar and salt of 1% does not affect it.
4. When the more sugar is added, the less foam is formed, but the stability increases.
5. When whipped egg whites are mixed in batter together with beaten yolks, soft texture of sponge cake is obtained.

Most of the white cloths made of synthetic fibers decrease their whiteness by repeating alternately wearing and washing, and their original whiteness cannot be recovered by treatment with either optical whitening agent or chemical bleach.
The authors thought that this fact was caused by fatty soils in water for a wash, and experiments were carried out to make this point clear. Hydrous lanolin was added into water in place of human skin lipids. Four kinds of soil solutions prepared from carbon black, lanolin, and detergent were used.
The results obtained were as follows :
1. In the laundering process, lanolin in the soil solution largely reduces whiteness of the cloths made of hydrophobic fibers.
2. Detergents in soil solutions always lessen the amount of soils depositing on the cloths.
3. The contamination made by fatty and carbon black soils on the hydrophilic fabrics, such as cotton and modified polyester, in the soil solution which contains detergents is nearly equal to the contamination made solely by carbon black in the soil solution containing detergents.
4. It appears that ester type compounds in fatty soil decrease whiteness more than other types.

Five kinds of markers were employed in the experiment. All of them were 0.75 mm thick, but were different in radius. The depths of marks made on several pieces of the same kind of cotton cloth with the markers were measured by a special microscope. The following results were obtained :
1. The smaller the radius of curvature is, the deeper the streaks made by the marker are, but the depth of the streaks is not in reverse proportion to the radius of curvature.
2. As the streaks deepen, something like nodes developes in the streaks, and sometimes projections grow at the ends of the streaks ; consequently the depth of the streaks decrease suddenly.

Three kinds of markers having the same thickness of 0.75mm and different radii were employed in the experiment. The depths of marks made on several pieces of the same kind of cotton cloth with the markers were measured by a special microscope. The relation between the observed depths and the contact area of the markers on the cloths was investigated. The following results were obtained :
1. When the depth of the marks made by the marker is small, contact area of the marker on the cloths is almost in reverse proportion to the depth of the marks made by the marker.
2. As the streaks deepen and the threads of the cloth are stretched to an extremity, the inverse proportionality between the depth and the contact area is gradually lost.

Continuing from previous work, I investigated harmony between neck design and the physical type. The girl-students among whom I could select models for the present experiment were from the area different from that of the students investigated in previous papers. First I examined their physical types in the same way as described in Part I. Then six girls were picked out as models of the tests. These models wore sample blouses of basic designs and variations, and their color slide pictures were made. Seven judges carried out sensory tests on the harmony of shapes concerned. The following is the summary of the tests.
1. The standing collar harmonizes with the long neck. Even if the neck is short, the deeply fixed collars are becoming to sloping shoulder type persons and narrow collars deeply fixed in the middle front suit square shoulder types. The wide-bottom neck type and collars which hide the sides of the neck go well together.
2. Open collars are generally in harmony with every type. Shortened V-neck-line makes the short neck and big face look conspicuous, although it gives young appearance. Wide overlapping collars make plump people look plump.
3. With regard to shirt collars, the same thing holds true as with standing collars mentioned above.
4. As for no-collar (collarless) design, the small neck-line and the long neck harmonize. V-neckline or deep neck-line hamonizes with short neck with big face. For wide-bottom neck type, deep neck-line which shows the neck bottom is not suitable.

Somatometric studies have been made in order to obtain the measurements and physical forms of each age group and find out a standard of measures of clothing.
In this report 22 items relating to length were measured with each sex children between four and six years of age. Changes with the growth in physical forms, measurements of parts and their indices in the stature were investigated.
The results are as follows :
The values of all 22 items gradually increase with age in both sexes. All items except malleolaris lateralis show significant difference between two successive years of age.
Sexual difference is not recognized in children of 4 years of age, but males of six years of age are slightly superior in sizes than females of the same age.
Since the correlation between stature and values of items of length is high in 4-6 years of age and the regressions of these three ages coincide with each other, these three ages should be taken to be physically one group in determining clothing sizes.

Twenty-three items of the girth were measured with children between four and six years of age in order to study the change of children's physical forms with growth and sex. Girths, breadths, depths and index-values of girths were measured and discussed.
The results are as follows :
The depths of head and trunk showed little difference between ages in both sexes, but girths, breadths and the vertical trunk girth increased greatly with age and their differences between ages were significant.
Index-values of girths to the bust girth did not change by age. The proportions of hip girth and thigh girth to the bust girth were higher in females than in males showing sexual characteristics.
The proportion of the bust depth to the bust breadth was greater in males, but depth-breadth ratio of waist and that of hip were greater in females.
Correlations of girths to the body weight were high, but correlations of breadths to the body weight were medium, in both sexes.

Daily activities of married couples are analyzed according to whether or not the wife is employed and whether or not they have children, and also according to the age of the youngest child.
The result has been compared with the data collected by the same studies made in 1956 and 1961.
The conclusions are summarized as follows :
The hours spent by non-employed wife for homemaking have gradually decreased in the past eleven years, regardless of whether or not the family has children, or regardless of the age of the youngest child, whereas the hours spent for social and cultural activities have increased.
However, employed wives, particularly those who have children, spend more time for home-making comparing with the data obtained by our previous surveys.

Daily activities of married couples are analyzed according to the number of children and the number of family members. Two types of couples-one with wives who are employed and the other not employed-are taken as the samples for the present studies. The results are compared with the data collected by the same studies made in 1956. The conclusions are summarized as follows :
(1) In both types, the hours spent for homemaking by wives who have two children are longer than those by wives who have one child. This fact is contrary to the data collected in 1956. This is caused by the change in the length of time for caring for babies ; the length of time for caring for one baby was longer in 1956 but that for two babies was shorter relative to the present.
(2) The hours spent for homemaking by wives who have four or five children are longer than those by wives who have three children. However, the significant difference is observed with the wives who are not employed and on weekdays only.

This and two later papers deal with the difference between father's and his child's opinions about occupation.
The survey took effect around Nagoya City in July, 1968. Fathers of the third year students of 16 junior and senior high schools were inquired about occupations, educational backgrounds and places of residence of their own and their fathers. The effective answers were 1167.
An analysis was made in an effort to clarify changes of social aspects such as occupation, education and dwelling in the generation from grandfather to father. It has become clear that changes in occupations are least with those who are engaging in agriculture, forestry and fishery, while the changes are comparatively great for those who have professional, clerical, and transportational or communication occupations.
The analysis of educational backgrounds revealed that the percentage of middle school graduates was ten with the grandfathers, but it rose remarkably to twenty-six with the fathers.

This report deals with fathers' and children's views of occupation, especially the difference between their views. The selected samples were the same as Part 1; that is, students of junior and senior high schools and their fathers. Effective samples for this report were 750.
The results show that a greater part of fathers take a pride in their work, but they think it is not a serious problem whether or not their children choose the same occupation as fathers. On the other hand, children are indifferent to their fathers' occupation, but at the same time they show a tendency that they do not like to engage in the same occupation as their fathers.
