February : — (Spence, R.) Journal of Voyage up the Amazon and Rio

 lia ; the Vine Disease. This notice is a translation of M. Tulasne's " Notes 

 on the Fungus which causes the Vine disease," extracted from the " Comptes 

 rendus des Seances de l'Academie des Sciences, vol. xxxvii. This fungus, 

 now well known under the name O'idium Tuckeri (Berk), consists of 

 a network {Mycelium) of white, loose filaments, which covers here and 

 there the green and healthy parts of the vine, and causes the formation of 

 brownish or blackish spots. From these filaments, which are all superficial 

 or external on the epidermis of the infested plant, spring thick tufts of 

 simple pointed stalks, the ultimate points of each of which quickly becomes 

 a large oval cell, as capable of propagating the fungus as any true seed 

 could be. Independently of these reproductive bodies, the Oidium Tuckeri 

 produces brown, generally pedicellate, fruits, coated with a cellular mem- 

 brane, and containing very minute seeds, capable of germinating. These 

 fruits are commonly larger than the swollen acrogenous bodies, described 

 above, but not always so ; they are of the same form, and are often borne 

 on the same footstalk, almost appearing as if they were caused by a trans- 

 formation of the normal seeds. From a close observation of these pecu- 

 liar organs, M. Tulasne conjectures that the O'idium Tuckeri is of a very
