Responding to Apgar's letter of March 21, 1939, Connell provided more information on "intercoupling" patient,
anesthetist, and gas machine with special static-reducing tape to prevent the generation of static sparks that could ignite
anesthesia gases and cause an explosion.

[written in top right corner in different handwriting, Received Apr 10 1939]
Dear Dr Apgar:
Dr. Williams will check and deliver to you the real thing, collodial [sic] graphite electroresistor tape. One end around the
patients arm and tucked under the mattress, the continuity say 4 feet to the apparatus [?] the further continuity to a cool
[?] which the anesthetist wears continually on the wrist when near the patient.
This intercoupling mandatory on all anesthesia and whatever instrument.
The only residual danger then is rubber static (and sodalime as catalyst???) Rubber is killed as a generator and holder of
static by rinsing in 4 percent [ . . . ]/2 and letting this dry on the rubber. Dr Williams has long preached this. The Roosevelt
explosion brings it acutely to the fore, for that explosion began in the sodalime, bag side of the flutter valves.
I will show the Bac 1/2 effect on rubber on Friday meeting.
