| Description | Capanema argues that the reason for the length of the pendulum beating seconds at different places is to do with numerous causes of error rather than imperfection in instruments. Capanema therefore suggests no alteration to the pendulum and measuring by the chronoscope. Describes his proposed apparatus including small diagrams depicting wire connectors with interrupting apparatus, arctic point, pendulum, chronoscope, and battery [see MS/257/1/279]. Capanema describes his method and experiments. |
