Mr. R. H. Niseett-Brown writes as follows : — 

 " Scientific measures are now made in metres and 

 divisions of the metre. The metre is itself a few 

 inches more than a yard long, and is defined by the 

 Act of Parliament which has legalised the use of 

 metrical weights and measures in the British do- 

 minions as equal to 39*37079 inches. The metre is 

 divided into raetrets, a convenient name for its 

 decimal subdivisions, that is, subdivisions each of 

 which is the tenth part of the one before it in the 

 series, and ten times the next after it. The deci- 

 metre, or tenth part of a metre, is the first of these 

 metrets ; it is about a hand-breadth, or i*6 milli- 

 metres less than four inches. The next metret is the
