and the povotcepais, no living representatives of any of which 

 animals can be supposed to have any existence in nature*. Na- 

 turalists are, we believe, agreed upon the point that the so-called 

 Unicorn is a fabulous animal from beginning to end. It has 

 merely been my object in this paper to show how utterly ground- 

 less is the foundation on which the whole superstructure rests. 

 We cannot, therefore, participate in the slightest degree in the 

 hope that Dr. Baikie will be more successful than his prede- 

 cessors.

Naturhistorisk Tidsskrift {Journal of Natural History), founded 

 by Dr. H. Kroyer; edited by Prof. T. C. Schjodte at Copen- 

 hagen. Third Series, 1861. [Kroyer, Contributions to the His-

The 'Naturhistorisk Tidsskrift,' or 'Journal of Natural History,' 

 founded by Dr. Kroyer of Copenhagen, which, from 1837 to 1849, 

 formed one of the principal means of literary communication for 

 Danish naturalists, will be remembered by all those who occupy 

 themselves with the fauna and flora of the North. The editor com- 

 municated through this channel a great many of his numerous and 

 valuable contributions to the natural history of Crustacea and Fishes ; 

 but in 1849 he was forced by different circumstances to discontinue 

 the journal, six substantial volumes having at that time been published. 

 Travels and declining health afterwards prevented Dr. Kroyer from 

 resuming the publication, which has thus been interrupted for twelve 

 years. At present, however, Professor Schjodte, whose name as an 

 entomologist is also well known in England, has undertaken the task 

 of continuing the journal ; and the first part of the third series 

 appeared a twelvemonth ago. That it is an undertaking deserving 

 the attention of English naturalists will appear from a review of the 

 volume before us. It is a matter of course that the majority of the 

 papers will always be in Danish ; but the affinity of this language to 

 the English is so great, that any person may easily acquire sufficient 

 Danish for consulting scientific treatises in that language. Besides, 

 the diagnoses and explanations of the plates are given in Latin ; this 

 is, at least, the case in the first part of the work, on which we will 

 offer a few remarks. 



It is headed by a paper from the pen of Dr. Kroyer, containing 

 descriptions of several species of Mysidee and similar Crustacea. 

 Dr. Kroyer was one of the naturalists who accompanied the great 

 expedition of 'La Recherche' to the Arctic regions, in 1838-1840, 



* Pliny (N. H. viii. 21) says that "there are in India oxen with solid 

 hoofs and a single horn." So here we have another kind of Unicorn.
