There is no description about Liancourt Rocks or Argonaut island although it referred to Dagelet island.
To follow is from the description of "Corea". It didn't mention Liancourt Rocks directly but many of the readers may think it's interesting.
COREA, or KOREA, ko-ree’ a, (called by the natives Tsyosien, by the Chinese, to whom it is tributary, Kao-lee, and by the Japanese, Ko-rai, ko’ri’, whence its European name of Corea, or Korea,) is an extensive peninsular country in North-eastern Asia, whose limits are not accurately known, bounded E. by the Sea of Japan, S. by the Strait of Corea, and W. by the Whanghai, or Yellow Sea, and the Gulf of Leao-tong. The capital, Kingkitao, is situated on the
, in the centre of the kingdom, lat. 37°40’N., and lon. 127°20’E. Corea comprises a peninsula with a small portion of the continent to which it is attached; the continental portion extending in breadth from lon. 124°to 132°E., the peninsula from lon. 125°15’ to 131°30’ E., between lat. 33°20’ and 43°N., its average width being about 135 miles, while the total length of the country, from N. to S., is somewhat less than 600 miles. Corea also includes numerous groups of islands in the Yellow Sea and Strait of Corea, and the island of Quelpart, 50 miles S. of the peninsula. Area of continental portion, about 80,000 square miles. Kiang River
The longitude 131°30' E. ,which was mentioned in the peninsula portion, would include Ulleungdo although it still excludes Liancourt Rocks.
Western people didn't think that Liancourt Rocks belonged to Korea in the 19th century at all, as many other books and maps indicated.
And to follow is about Dagelet island (Ulleungdo):
An island in the Sea of Japan, about midway
between Japan and Corea, 8 miles in circumference. Lat. (N.point) 37°25' N.,
lon. 130° 56' E.
GTOMR found that "Matsushima-No-Gi (Arguments on Matsushima)" from the three-volume book "A Study of Historical Evidence of Takeshima (竹島考証)" (1881) mentioned this "Pronouncing Gazetteer of the World" in its Section No.12 "Argument on Matsushima II".
The description of ”section No 12 Argument on Matsushima II" ( 第拾貳號 松島之議ニ) is as follows:
