Urcdinca? must have existed as parasites during a longer period of time 

 than Botrytis or than C'uscua. The phenomena are very complicated, 

 and it is not always easy to decide whether they are not in some cases 

 also morphologically distinct. 



Diseases of Plants, with Methods of Prevention or Cure.* — J. 

 Kindshoven recommends treatment by spraying with copper-lime or 

 copper-soda solutions for the extirpation of fungal diseases. He proved 

 the value of this method in overcoming an attack of Pears by Fusi- 

 c Iridium . 



W. Freckmannf describes the development oiSclerotinia Trifoliorum, 

 which, he finds, attacks Trifolium pratmse, T. incarnatwn, T. hybri- 

 durn, T. pannonicum, Onobrychis sativa, Medicayo sativa, Anthyllis 

 vulneraria, and Lupinus permnis. The fungus attacks plants three and 

 four years old, as well as the seedlings. To stamp out the disease, it is 

 necessary to prevent the sclerotia from germinating ; they should be 

 deeply ploughed in. A change of crop is also recommended.
