Richard Roberts. This model, which is thought to have been 

 constructed about 1836 or 1838, was afterwards copied on a 

 scale sufficiently large to convey a living traveller, and was 

 exhibited in Manchester, Liverpool, and other places. The 

 model is now the property of the Sal ford Corporation, and is 

 deposited in the Peel Park Museum. 



Mr. W. E. HoYLE, M.A., exhibited some coloured photo- 

 graphs prepared by the Sanger Shepherd process, which consists 

 in taking three negatives of each picture through differently 

 coloured screens, and then making positives which are stained 

 with a colour complementary to that of each respective screen. 

 When these are superposed, there results a slide which 

 reproduces very accurately the hues of nature. The series 

 exhibited included butterflies, shells, flowers, fruit, portraits and 

 landscapes, taken direct from the natural objects, as well 

 as copies of coloured prints, lithographs and illuminated 

 manuscripts. 



Mr. Francis Jones, M.Sc, read a paper " On the Action 

 of Alkalies on Glass and on Paraffin."
