 (R. J. Farrants) A Micrometer object-finder. Report of the Committee ap- 

 pointed by the Microscopical Society for the purpose of ascertaining the most 

 convenient form of finder for indicating the position of objects under the 

 Microscope — the point from which the distance of objects must be taken has 

 been fixed on as the centre of the slides — which are, or at least always ought to 

 be 3 inches by one — this at once gives the starting point for an universal system 

 of measurement. And we think the details which the Committee give in this 

 paper would be easily carried into execution by any optician. The Finder they 

 recommend is alike adapted to Microscopes with or without stage movements.
