1 It was the behaviour of this series which suggested to me to test the germination of 
the spore according to the age of the leaf, &c. 
(36) Vigorous germination. (37) Poor. (38) None germinated in 24 hours. 
(39) Fairly vigorous. (40,41) Poor. (42) None germinated : appeared paralysed. 
(43) Fairly vigorous. (44) None germinated : as if paralysed. (45) Poor. 
(46) Very vigorous. (47) None germinated : as if paralysed. 
(48) Very vigorous. (49) None germinated. (50) Very vigorous. 
(51) In 1 1 hours vigorous germination and tubes as long as the spore: in 3 hours = 4-5 spore 
diameters and branching : in 7 hours 12-20 diameters and much branched. 
(52) Very vigorous in both light and dark. In ij hours tubes =1-2 spore diameter: in 
3 hours = 6-8 diameters and branching. In 7 hours = 12-20 diameters and much branched. 
(53) Total inhibition. (54) Total inhibition in two trials. (55) Total inhibition. 
(56) In 1 1 hours none germinated : in 3 hours several have tubes 1-3 spore-diameters in 
length. In 7 hours many have tubes 8-10 spore-diameter. Same in watch-glass. 
(57) Similar results, both in light and in darkness. 
(58, 59) Vigorous germination in 2 hours. (60) None germinated in 2 days. 
(61) On thawing at I9°C none had germinated in 2 hours, but after 7^ hours several spores 
had put out tubes, and next day the germination was fairly good and general. 
(62) No recovery even in two days at 13-19 0 C. 
,(63) Normal germination. (64, 65) No germination.
