186 THE PEKIN OBSERVATORY. 



According to those who have studied them, the accuracy of the instru- 

 ments is questionable, the Chinese artisans charged with the gradua- 

 tion not having reproduced with exactness the models given to them. 



Nowhere is there met a trace of a telescope or even of a simple tube 

 capable of concenti-ating the visual ysljs of the observer upon a single 

 point. The pinnule is alone employed for observations. Fortunately 

 for science, alongside of this official observator}', the Cluny Museum 

 of Chinese Astronomy, stand some establishments, such as Lika Wey, 

 in which are found the most improved models of contemporar}' optics. 

 For our enoravings we are indebted to L'lllustration.
