ventilation at all was provided and with less space
between the top of the battery and the underside of
the lid{A. J. Lidsey} than at present, very little trouble or none
was experienced from corrosion.

Improvements in the design of the cell cover and
terminal glands are always under consideration, in fact
we have now experimentally an improved form of cell lid{A. J. Lidsey}
with rubber terminal gland in addition to the vaseline
gland, and this is likely shortly to become standard.

It will be understood that we think the corrosion
complained of was the temporary result of one modification
fundamentally in the nature of an improvement, shewing
up another fault which required rectification.
