exotic plant and very rare, the Puccinia graminis and its ravages 

 in cereals are frequent. 



Prof. A. B. Griffiths, of Lincoln, whom I have already cited, 

 has recently advised sulphate of iron as a remedy against Corn 

 Mildew; the quantity to he 88 lhs. to the acre. 



I have already said that my reason for taking the liberty of 

 presenting these reflections, overlengthy, perhaps, is the imper- 

 fect popular acquaintance which there seems to be, in this 

 part of England, with modern investigation in regard to fungi. 

 I should, however, also say that the manner in which some of 

 the English books are written, those most consulted and fol- 

 lowed respecting fungi, does not seem calculated for the proper 

 education of public opinion. I will merely cite two examples: 

 the undoubtedly important work of M. C. Cook, "Handbook 

 of British Eungi," 2 vols., 1871, seems to be behind the year 

 in which it was published. In 1882, Mr. Thomas Brittain, 

 President of the Manchester Microscopical Society, published a 

 small popular work called " Microfungi, When and ivhere to find 

 them" which, principally on account of what it says on pages 

 24, 44, 70, 74, and Plates I. and II., does not for the same 

 reason, seem to me, to correctly guide the opinion of agricul- 

 turists.
