have previously been found only in the salt pools near Torrla 

 and Szamosfalva in Transylvania. 



On the whole the Protozoan fauna of the salt-pool near 

 Deva agrees pretty well with that of the pools at Torda a)id 

 Szamosfalva, but in Enfzia tetrastomella and Amphidinium 

 operculatum it has to show two species peculiarly character- 

 istic of this pool. 



BIBLIOGEAPHICAL NOTICES. 



Vergleichende Moiyhologie unci Biohr/ie der Pilze, Mjicetozopn vnd 

 Bacterien. Von A., de Eary, Engtimaun : Leipzig, 1884. 



It may be said at once that no more Avelcome contribution conld 

 have been made to botanical science at the present time than Prof, 

 de Eary's new book. Eighteen years ago, when he published the 

 ' Morphologic und Physiologic der Pilzc, Elechtcn und Myxoray- 

 ceten,' students of the^e organisms were presented with a treatise 

 embracing the whole field of a subject where were lying scattered 

 abundant materials sorely in need of critical selection and anange- 

 mcntr. Of Prof, do Ikry's special qualifications for the task it would 

 not become me to speak ; it is sufiicient that they enabled him to pro- 

 duce a book which may be said, without the smallest fear of contra- 

 diction, to have given an impulse to the study amounting to a new 

 departure in its history. This sowing of fresh seed has again 

 yielded so fruitful a crop in the hands of many active workers that 

 a new edition of the text-boolv has for some years been greatly 

 wanted. The present work supplies the want, and testimony of the 

 extent of the advance that has been made appears in the fact that 

 it is in reality a new book, resembling the former, perhaps, more in 

 the thoroughness, vigour, and fertile thought displayed in its pages 

 than in the special treatment of the matter. During the interval 

 between the two books there arose such an accumidation of material 

 to be dealt with, and entangled with it so many points of controversy 

 to be discussed, that not only a fresh treatment of the matter be- 

 came necessary, but a limitation in some measure of the scope of 

 the treatise. The physiology of fungal organisms has received so 

 much notice in the general physiological works of Sachs and Pleffer, 

 and in the vast literatuie that has grown up on the subject of fer- 

 mentation, that Prof, de Pary has rightly considered it expedient to 

 deal with it less fully in the circumstances. But, as we are 

 reminded in the preface, morphological treatises of great extent 

 can scarcely now (and certainly not in the present instance) be satis- 

 factorily produced without constant reference to the phenomena which 

 are specially termed biological — the modes and the adaptations of 

 life ; and in dealing with these one necessarily comes in contact with 

 purely physiological matters.
