One juan. White bamboo paper in one ce, forty-two folios (ff. 8–10 and 29–31 are missing).

The title page is xylographed in Latin from the handwriting of Verbiest with the date 1668, which engraving was done in Beijing: Astronomia Europaea | sub Imperatore Tartaro Sinico | Cam Hy appellato | Ex umbra in lucem revocata | A P.

On the twenty-first day of the eleventh month, the seventh year of the Kangxi reign, we had an unexpected visit from four Grand Secretaries sent by His Majesty, namely, His Excellency Wu Gesai 吳格塞, His Excellency Duo Nuo 多諾, His Excellency Zhuo Ling’an 卓令安, and His Excellency Fan Chengmo 范承謨, all of them now deceased. His Majesty wanted to know whether the calendars then issued were correct. My reply was that they were very erroneous and that I had solid argument for saying so. There and then I pointed out the errors of these calendars. His Excellency Duo referred my reply to the emperor. The following day (22nd) an imperial order summoned me, An Wensi 安文思 [Gabriel de Magalhães], and Li Leisi 利類思 [Lodovico Buglio] to present ourselves at the Donghua Gate. On that same day the officials of the Imperial Observatory, Ma You 馬祐, Yang Guangxian, and Wu Mingxuan, were also there. [There followed a disputation between Yang, Wu, and Verbiest]. It was proved that the calculation of the calendar was incorrect and by imperial order the Qizheng minli 七政民曆 was compiled in the eighth year of the Kangxi reign by Wu Mingxuan, then Vice president of the Imperial Observatory, to be examined carefully for definite errors . . .

Xinfa biaoyi 新法表異.
By Tang Ruowang 湯若望 (Johann Adam Schall von Bell).
Two juan. Bamboo paper, one ce.
No date or place of publication.

The cover bears a label with the title and a Latin inscription: “Differentia inter Euro | paeam et sinicam astro | nomiam | a p. Adamo Schall | S.J. | 2 tomi.”

The Xinfa biaoyi (Divergences of the new calendar) was written about 1634. It is divided into two parts. Juan A is a general study of the ancient Chinese calendars. According to Schall, although it had been said that there were over seventy calendar experts in the history of China, in reality, there were only forty odd. Juan B deals with the new calendar adopted by the Manchus after fall of Beijing in 1644. It is the Western calendar introduced into China by the Jesuits.
Folio 35 of juan A gives a brief account of the reform of the calendar at the end of the Ming dynasty:

The proposal for calendar reform was first made in the Wanli reign, and the decision was made in the Chongzhen period. It was in the jisi 己巳 year (i.e., 1629, Chongzhen 2), when I was summoned [to the capital] where I wrote [books] and set up instruments. Six years later, the calendar was ready, and after verification both before and after, we found [the calendar] to be in close accord with the celestial movements. At that time, there was a scholar, Wei Wenkui 魏文魁 by name, known as a calendar expert, who had been in the service of His Excellency Xing Yunlu 邢雲路, the Surveillance Commissioner 按察使. This man had written a book entitled: Lüli kao 律曆考. He too came with his disciples and having presented a memorial to the throne, he petitioned that a calendar bureau should be set up for his school with the intention of competing with us. His calculations were later found to be inaccurate and he was dismissed. The new system continued to prevail. In the Forbidden City, His Majesty himself took interest in the calculations and time and again gave high praise to our achievements. Unfortunately, the situation of the empire was precarious and became worse as time went on. With uninterrupted warfare throughout the empire, it was impossible to promote the new calendar, a fact that was lamented by many contemporaries.
