Mr. A. D'Abbadie also writes* to say tbat "here" (presumably 

 Paris), micron is currently used to express the 1/1000 mm. ; while 

 Mr. K. B. Hay ward proposes "j" a new nomenclature which would convert 

 the micro-millimetre into a " hexametret." 



The Council of the Society having considered the question raised by 

 Prof. Kiicker, decided, as announced at the April Meeting, that the term 

 micron should in future be used in this Journal and in the official pro- 

 ceedings of the Society, in place of micro-millimetre. It was felt that 

 the term micrometre from its similarity to micrometer (especially in 

 French) was unsuitable.
