XI ZE-ZONG BO SHU-REN(Institute of History of Science Academia Sinica)
In this paper is presented a new revised catalogue of ancient novae, being a supplement and correction of a paper published in 1955. The first section describes the criteria of selecting the items which may be regarded as nova and gives the resulting list. Up to 1700 there are all together 90 items of novae observed in China, Korea, and Japan. In comparison with the former paper only 53 items are retained in the table, and 37 items are newly added. In the second section are discussed 12 possible supernovae and their identification with 11 radio point sources. The third section deals with the spatial distribution of supernovae and it is found that the frequency of occurrence of supernova in the Milky Way is about one in every 50 years on the average.
