In this paper, the conditions for dyeing cellulose in red with anthocyan were suggested.Cyanidin and pelargonidin were used as anthocyan. The number of hydroxyl group in the B ring in the chemical structure of anthocyanidin is two in the former and one in the latter.The results obtained were as follows : Cellulose treated with acidic materials such as tannic acid or thyntan were dyed in red with anthocyan solutions adjusted to pH 2, 3.4 and 4.Then, the important factor to consider when dyeing in red with anthocyan is to ensure that the acidic materials are free from constituents which form chelates with anthocyan, and that the anthocyan molecule does not have the structure to form chelates with metal ions in the mordants.Silk was directly dyed in red effectively in an acidic solution of anthocyan.

Skin lipid on the underwear worn by 30 high school female students for 24 hr was determined by the same method mentioned in the previous paper.<BR>The results obtained are as follows : <BR>1. The amounts of skin lipid stuck to the underwear worn by girls aged 16-17 years distribute considerably widely ranging from 0 to 43.18 mg and the distribution has the mode at 13 mg. The value of the mode is equal to that for high school male students. The skewness that indicates departure from the normal distribution of the data is only +1.06, and it is very different from that for boys.<BR>2. The distribution range and the mode of the amounts of skin lipid on high school female students' underwear are about twice the width and the quantity of those for 1314-year-old pupils'.<BR>3. The amount of skin lipid on the underwear worn by boys or girls shows a rapid rate of increase during they grow older from 1314 years to 1617 years old.
