A uredospore is shown in fig. 3, whilst fig. 4 depicts four 

 teleutospores, two of which are germinating ; one of the 

 germ-tubes bears four promycelial or secondary spores. All 

 the illustrations of spores are highly magnified. 



Before the life cycle of this fungus was properly understood, 

 the stage on the currant leaves was considered to be a distinct 

 species of fungus, and was christened Cronavtium ribicolum. 



Curiously enough, it is said that the Peridermium strobi does 

 not occur in America, the home of the Weymouth-pines f 

 The Weymouth-pines in the plantation at Inval have been 

 carefully kept under observation since the 1901 attack. In 

 1902 the Peridermium was not abundant. The ascophores of 

 the larch canker {Dasyscypha calycina = Peziza willkommii) were, 

 however, abundant on many branches which had been killed 

 by the Peridermium the previous year. 



In July, 1903, many of the trees showed the Tubercularia 

 fairly abundantly. 



In 1904 the trees yielded neither Peridermium nor Tuber- 

 cularia, but the Peziza was abundant on dead and dying 

 branches. 



During the present year a few isolated branches on some of 

 the trees have died ; these bore ascophores of Dasyscypha 

 calycina. The Peridermium has not been observed.

 gest a new life of Cobbett was a desideratum. We knew 

 only of the too detailed and by no means impartial bio- 

 graphies of Huist and Edward Smith. The most unfortunate
