	Hey, Stroud, what am I
supposed to do with him, huh?
1:04:15
	What am I gonna do?
1:04:20
	Hey, Bob?
1:04:30
	Stroud struck back
at the oldest enemy of all.
1:04:34
	Wash the cages, sterilise
the cell from top to bottom,
1:04:39
	read everything in
the prison library about birds.
1:04:43
	He learned of oxidisers, which had been
used as a poultry germicide for years.
1:04:48
	He wrote to his mother, asking
for these drugs, plus equipment.
1:04:53
	While waiting, he tried
fantastic concoctions on his birds,
1:04:57
	like a sulphur solution
made from the heads of matches.
1:05:11
	The birds died with increasing swiftness.
1:05:15
	The package of drugs and
equipment came from Mother.
1:05:19
	With little or no knowledge of the amount
of chemicals a canary could tolerate,
1:05:23
	Stroud proceeded to administer
the oxidisers to his sick birds.
1:05:39
	Clearly, this drug was
no cure for septic fever,
1:05:43
	but Stroud persisted,
trying different combinations.
1:05:51
	The birds still died.
1:05:53
	However, Stroud made one discovery:
1:05:55
	before death, their temperature
dropped to normal.
1:05:59
	He concluded the chemicals
were too harsh, too caustic.
