 types. 



Some omissions are quite surprising. Thus, while Enrothun is 

 described as a typical ascomycetous fungus, there is no suggestion 

 of a possibility of the existence of sexual organs or a sexual process ; 

 and the only mention of Collema is as an instance of a gelatinous 

 lichen. Hepatics are dismissed in four pages, and the account con- 

 sists mainly of a description of a by no means typical example, viz. 

 Marchantia. Mosses are as badly treated. Phanerogams are intro- 

 duced as " plants in which the organs of sexual reproduction, always 

 highly differentiated, alone or accompanied by accessory organs, 

 constitute a flower." The all-important idea of the seed does not 

 enter into the definition. 



We wonder how M. Courchet and his pupils got through the 

 exhaustive list of natural orders which make up the bulk of the 

 book. It is stated in the preface that the students took a real 

 pleasure in the natural sciences, and we hope the remai'k applies 

 also to this branch. But we are of the opinion that more pleasure, 

 and profit too, would have been derived from a careful comparative 

 study of one-fifth of the number of orders, and those by preference

 abundant and on the whole good ; many are old friends, used with- 

 out any acknowledgment of their source. A "R "R
