Excerpt from Special Announcement for Session 1891-92
The instruments for making the electrical measurements have been selected with much care; these instruments will enable measurements of current resistance, and difference of potential to be made with great se curacy, not only in the detached laboratories but in the dynamo room when the machinery is running; in separate rooms there are standard instruments of extreme precision with which the correctness of the work ing instruments can be readily checked. These include amongst others, tive of Sir William Thomson's beautiful electric balances. There are also a variety of instruments for special purposes connected with electrical measurements, such as instruments for determining coefficients of self and mutual induction, etc.
