Harshbergrer's Mycology and Plant Pathologry* 



The author has compiled a lot of undoubtedly useful informa- 

 tion and therefor deserves our sincere thanks. He has, however, 

 undertaken a difficult, if not, indeed, impossible task in trying to 

 combine successfully under one cover the subjects of mycology 

 and plant pathology. Perhaps, however, the experiment has 

 been worth while if only for the value of the encyclopedic com- 

 pilation, notwithstanding the fragmentary treatment of some of 

 the subjects. 



The style is unfortunately at times rather involved and ob- 

 scure; commas are often used wrongly or else omitted where 

 necessary to make the meaning clear. The ending "ic" is used 

 fairly consistently throughout the book; sounding rather poetic 

 in such words as "chemic," "technic," "the mycologic student." 

 But chemical, physica/, typica/, spherica/ have occasionally 

 slipped by, along with some careless proofreading, such for 

 instance as the failure to transfer pp. 324 and 325 to the end of 

 Chapter XXIV and the inverted figure on page 229. "Fun- 

 guses" is rather unusual; and the interpretation of "geographic 

 distribution of fungi" as a study of "habitats is somewhat 

 strained." Strict adherence to the Engler-Gilg syllabus and 

 disregard of recent researches, in particular certain American 

 ones, has made his treatment seem rather archaic in places.
