charm even in its simplicity. The nomade sleeps on his hide 90 

 close to the grass, that he is only separated by planks ; he almost 

 touches it, and breathes its fragrant perfume. When the grass be- 

 gins to perish, the Nogai moves his hut to a different spot. The 

 landscape is uniform, and the green carpet is the same ; but he can 

 distinguish each individual in the flock, and his eye extends over 

 the whole of his possessions. 



Count Potocki, after his arrival at Taman, passed the Bosphorus, 

 and returned to Europe after a journey of eleven months. We have 

 endeavoured to convey some general idea of the nature and object 

 of his researches rather than to criticise the results. Of the most im- 

 portant of these, on the contrary, we have, as far as was in our power, 

 given careful sketches; and we shall, probably, in a future number, 

 pay the same well-merited compliment to the primitive history of 

 the Russian tribes, which, accompanied by important notes by Kla- 

 proth, constitutes the second volume of the work. 



Anthropogenese, Sfc. Anthropogenesis, or the Generation of Man, 

 with comparative views on the re-production of the Three King- 

 doms of Nature; by J. B. Demanoeon, M.D. &c. Paris: 

 Rouen Freres. 1829. 



Although the proper study of man may be man himself, yet 

 man, who has for ages been engaged in the study of all things ex- 

 ternal and internal, has yet not perfected his knowledge of what it 

 most concerns him to know. The author of the Anthropogeneis 

 has chosen an interesting department of the great science of the 

 microcosm, and has treated it in an interesting manner. The sub- 

 j ect, he says, he has found so difficult to manage, that he has been 

 obliged to make numerous excursions into the three kingdoms of 

 nature, and to draw from them whatever he could find illustrative. 



The first chapter treats of generation in the species whose sex is 

 known ; the second of generation in those whose sex is not known. 

 Generation is the act by which the elements, kept in reserve by 

 nature for a new individual organization, are united and vivified. 

 In vegetables, the pollen introducing itself by the stigma into the 

 style or vaginal canal of the ovary, gives rise to the formation of 

 the seed, which, on being placed in a favourable situation, repro- 

 duces the species of plant from which it was derived. In the most 

 perfect animals, generation is efi"ected through the means of copu- 

 lation, by impregnation, which is the application of the seminal 

 fluid of the male to the eggs or sexual product of the female ; and, 

 in some species, without copulation, by the mere sprinkling of the 

 fluid of the male upon the eggs after they have been deposited. 

 In this kind of generation, which is called univocal, the germ pre- 

 existing in the product of the female is vivified and developed.
