Title | Paper, 'On a method of determining the value of rapid variations of a difference of potential by means of the capillary electrometer' by George J [James] Burch |
Date | 1890 |
Description | Burch writes: 'In 1882 a paper by Professor Burdon Sanderson appeared in the "Biologisches Centralblatt", in which an account was given of the employment of photography for the production by means of the capillary electrometer of records of the electrical phenomena accompanying the excitation of the leaf of Dionaea. Other physiologists have availed themselves of this method for the purpose of determining the times at which the electrical changes in living tissues begin and end, but no complete investigation has been made of the relation between the curves obtained and the amount of variation of the difference of potential of which they are the expression.'
