Meteorological Observations. 875 
THE POTATO FUNGUS. 
Mr. Moore of Glasnevin has sent me this morning a leaf of a po- 
tato clothed with our old enemy Botrytis infestans, from potatoes in 
the Royal Botanic Garden, Dublin. Everything seems to tend to a 
repetition of the ravages of last year. I can persuade nobody here 
that there are any fears, and all advice is vain.—M. J. B. (Garden- 
_ers’ Chronicle.)
