Professor Dodds' Bentley Car & Sparking Plugs. Sg.{Arthur F. Sidgreaves - MD}3/D.22.7.36. Sg.{Arthur F. Sidgreaves - MD}13/D.21.7.36. We will investigate Professor Dodds' complaint while he is away, and in any case will have the car at Park Ward's by the 9th August for the painting. All porcelain plugs are weaker mechanically than Mica plugs. We are in communication with America and are also working with General Motors in England, to determine whether Mica is the basic source of our trouble, or some other feature of design.
