the like, at do a vast deal of damage. As an instance we may al- 
lude to the malady of the grape, which for the last year or two has so 
seriously diminished the product of this important culture in the south 
of Europe, Madeira, &c. This memoir, like its aggre: (in 1847), 
_ of which all successful remedial or preventive measures will 
have to be based. As Fungi, even of these tribes, are beginning to be 
studied in this country with much zeal, we have only to call the atten- 
tion of our mycologists to this able paper, and to say that the general 
physiologist will also find it of no small interest, from the light it sheds 
‘some of the simplest forms.of vegetable existence. M. Tulasne 
devotes much cieoige to a curious complication which occurs in these 
otherwise so simple plants; the lowest organized forms being almost 
uniformly intimately associated with those of a different and higher or- 
ment; some have contended that one species was here parasitic upon 
aaniher. itself a parasite ; while others look upon these cases as a kind 
o Penorphie in fructification, comparable with what is known to occur 
in a good many Phzenogamous plants. The latter view is penieene 
med M. Tulasne, and its correctness is nearly demonstrated.
