In the former paper, Miyagawa et al. reported on Kohsai Udagawa's writing on albumen-on-glass photography, entitled “Potokarahii”. Yokusai Ihnuma who lived in Mino was Kohsai Udagawa's real father, and was one of famous scientists in 19th Century. He and his followers tried photography. Among them, his nephew, Ryuh-a Kojima was a tallent photographic technician. He opened a photographic studio in Gifu-ken, which was the first one in this prefecture. In 1873, he made an interesting collage picture composed of his familie's and his own portraits. It could be the oldest one of such kind of pictures in Japan. Yoshihiro Kuze studied photography with Yokusai Ihnuma in the Chemical Institute of the Ohgaki Clan. Reiji Esaki opened his photographic studio in Tokyo. He studied, at first, wet-collodion process, subsequently, he tried to use imported dry plate to take picture of rapid moving objects. In addition to them, he developed collage picture making. He made a surprising one composed of 1700 babies' photographic portraits which were taken with dry plate, in 1893.

Examinations were made on the action of anhydromevalonic acid lactone, which inhibits incorporation of mevalonic acid into cholesterol in the cell-free system of rat liver, on microorganisms was studied. Microorganisms examined were mevalonic acid-requiring Lactobacillus acidphilus ATCC 4963 and L. heterohiochii H-1,and Saccharomyces cerevisiae and S. carlsbergensis ATCC 9080 which do not require mevalonic acid and have the ability to synthesize sterol. In the presence of 0.1 μg/ml of mevalonic acid, L. acidophilus required ca. 15 mg/ml of anhydromevalonic acid lactone for 50% suppression and 25 mg/ml for 100% suppression. In the presence of 1.0 or 4.0 μg/ml of mevalonic acid, L. heterohiochii required 0.5 and 20 mg/ml, respectively, of anhydromevalonic acid lactone. In the presence of 15 and 20 mg/ml of anhydromevalonic acid lactone the growth of S. cerevisiae and S. carlsbergensis was completely inhibited. However, there was hardly any effect on the sterol content per unit cell weight.
