Wiirtemberg, including the principalities of Heicliingen, Sig- 

 manigen, and Fiirstemberg, and the neighbouring portion of the 

 Duchy of Baden. This plan in relief is 26 Parisian inches by 

 20, and is formed upon the same scale as the section published 

 by M. Alberto in 1826, in his work on the Mountains of Wiir- 

 temberg. The proportion of the horizontal distances to the 

 heights is as 1 to 18, and in this the higher portion of the 

 Swabian Alps has, in the plan, the height of one inch and a half, 

 and so on in proportion the other mountains. Professor Schiibler 

 of Tubingen, who has superintended and assisted in the work, 

 will contribute a treatise on the heights and on the geognosy of 

 Wiirtemberg. The colouring may, according to the wish of the 

 purchaser, be made to express either the leading geognostical 

 features of the country, or the natural appearances of the sur- 

 face. The price of a copy of either kind is 20 florins 24 

 kreutzers; and of both kinds if the two are taken by the same per- 

 son, 44 florins. Geognostical Maps of Wiirtemberg, coloured 

 by M. Rath after the original map by Professor Schiibler, are 

 also to be had at Tlibingen.

14. Hermaphrodis7n.' — M. Isidore Geoflroy Saint-Hilaire con- 

 siders the generative apparatus altogether as formed of six prin- 

 cipal segments, which in several circumstances are independent 

 of each other, to- wit, of the right and left side; these are, 1st 

 and 2d, deep-seated organs (ovaries, or testicles and their ap- 

 pendage) ; 3d and 4th, the intermediate organs (the womb or 

 prostate, and the vesiculae seminales and their appendages) ; 

 5th and 6th, external organs (clitoris and vulva, or penis and 

 scrotum). The facts which the author states, establish the in- 

 dependence of these six segments, and shew, that there is not 

 one of them which may not present sexual characters, the re- 

 verse of those of all the rest. These six segments correspond 

 to six orders of diff*erent vessels ; the deep-seated to the sperma- 

 tic arteries, the intermediate to the branches of the hypogas- 

 trius, and the deep-seated (les profonds *) to branches of the ex- 

 ternal iliacs. M. Geoff*roy divides the numerous cases of her-
