- Editor's Notes
- "We have been running about a year on a slow running pump taking off 9 runs a day. ## Are you absolutely sure that this form of pump is better than the quick working pump from which 11 runs can be taken off daily at the same expense? ## You will remember that we changed when you were working regarding mercury vapors."
