As a part of series of "Studies on Inorganic Chinese Drugs in Korea" four arsenic mineral Chinese drugs were analyzed by emission spectrographic method, and also were studied crystallographically by X-ray diffraction method. The following results were revealed: 1) Tang-shin-suk was not a Native arsenic but a Arsenolite which containing 94% of $As_{2}O_{3}$, 2) Toh-shin-suk was Crade Aluminum silicate 3) Woong-whang was a Realgar $As_{2}S_{2}$, 4) Yeh-suk was a Ca-Al-Silicate which was mixed with .alpha.-quartz contaminated by Iron compound and trace amount of Arsenic. It was not verified that the presence of Arsenopyrite FeAsS which has been believed as a main component of Yeh-suk by a Japanese author Wakimizu, nor the presence of Arsenolite which was reported by Masutomi.
