4 leaves July 30' in 2 dr. of 3 gr. of extract of Hyosciamus to 1 oz of water put on at 8˚ 14', & placed in 2 dr of Ph. of Amm. (1 gr to 20 oz) ie. on 2˚ 14) at 10. 34' immense inflection round immediately — They were somewhat somewhat inflected when put into the Phosphate.
10˚ 46' all 4 leaves greatly inflected — It is certain that 2˚ 20' of immersion in Hyosciamus (3 gr to 1 oz) does not in the least retard inflection)
