measurement of electricity should be made and approved by Her Majesty
in Council as Board of Trade standards.

(2) That the magnitudes of these standards should be determined on the
electro-magnetic system of measurement with reference to the
centimeter as unit of length, the gramme as unit of mass, and the
second as unit of time, and that by the terms centimeter and gramme
are meant the standards of those denominations deposited with the
Board of Trade.

(3) That the standard of electrical resistance should be denominated
the ohm, and should have the value 1,000,000,000 in terms of the
centimeter and second.

(4) That the resistance offered to an unvarying electric current by a
column of mercury of a constant cross sectional area of 1 square
millimeter, and of a length of 106.3 centimeters at the temperature of
melting ice may be adopted as 1 ohm.

(5) That the value of the standard of resistance constructed by a
committee of the British Association for the Advancement of Science in
the years 1863 and 1864, and known as the British Association unit,
may be taken as 0.9866 of the ohm.

(6) That a material standard, constructed in solid metal, and verified
by comparison with the British Association unit, should be adopted as
the standard ohm.

(7) That for the purpose of replacing the standard, if lost,
destroyed, or damaged, and for ordinary use, a limited number of
