Mr. Crisp called attention to a Chinese book on natural history, having 

 an illustration which represented a Microscope almost identical in pattern to 

 the one from Japan exhibited at the meeting of the Society in May last. It 

 would be remembered that this instrument was much criticised at the time 

 by Mr. Beck, who threw doubts upon its Oriental origin ; but it was clear, 

 from the figure given in this book, that the pattern was one recognized in 

 the East as a typical form of Microscope. He was sorry Mr. Beck was not 

 present, so that he might see the illustration. 



Prof. M. Thnry's note was read, describing a multi-ocular Microscope, 

 which he had designed for facilitating class demonstrations. It had several 

 body-tubes and eye-pieces, the image being thrown into each tube succes- 

 sively by the rotation of a total-reflection prism placed over the objective. 

 The teacher and his pupils could thus view the same object without having 

 to change their seats {ante, p. 796). 



Mr. Crisp exhibited, in connection with the note, the bi-ocular and 

 tri-ocular Microscopes of M. A. Nachet, and the quadri-ocular Microscope 

 of Prof. Harting. 



Mr. J. Mayall, jun., said that, with regard to Prof. Harting's quadri- 

 ocular Microscope, he found that M. Nachet claimed to have made such a 

 Microscope, and to have communicated with Prof. Harting about it in 1854. 

 M. Nachet had recently forwarded a drawing of the particular prism which
