At Berlin, the Scientific Society (_Winenschaftlicher Vereins_) have been giving a course of lectures to a large and aristocratic audience, invited by members of the society. Their success has brought out the Evangelical Society, in another course of a more theological and religious nature. In the first-named society, Professor Brandes lately lectured upon the Mormons; but it seems that the majority of the elegant gentlemen and ladies, did not fully appreciate his efforts for their instruction, for want of the necessary elementary knowledge. "When the doctor rose and announced his subject, the question was at once whispered in all parts of the hall," "Who are the Mormons?" The ladies in the most brilliant costume were generally the most eager in this inquiry. But unfortunately they got no satisfaction; the common reply of the gentleman appealed to being, "I am sorry to say I have forgotten." Some, more learned than others, however, assured their lovely companions that the Mormons were an Indian tribe of America, closely connected with, if not directly descended from, the Hurons, so frequently mentioned in Cooper's novels. Another amusing misunderstanding recently occurred in the same course. The lectures are not generally announced before-hand, but one day the newspapers got hold of the subject, and informed all the world that Professor Diterici would read a lecture upon _Pera and the desert festivals_. A great crowd of ladies was the consequence, all agog to hear about the picturesque costumes and strange ways of Pera, the national festivals of the Bedouins, and, perhaps, to have a glimpse at the mysteries of the seraglio. How great was the disappointment of the fashionable auditory when the learned doctor rose and began his discourse upon _Petra, the Fastness of the Desert_. That evening the ladies went home in very ill humor. * * * * * A work which political students and legislators may read, with advantage, is the _Wesen und Verfassung der Laadgemeinde_ (Nature and Constitution of the Country Towns, and of the tenure of Real Estate in Lower Saxony and Westphalia, with special regard to the Kingdom of Hanover.) It is by Mr. STUVE, recently the Prime Minister of Hanover, and is interesting, especially as exhibiting the extent to which the principle of local self-government obtains in Germany, and the probabilities and methods of its extension. For its historical view of the organization of the _commune_ or township in Germany, it is very valuable. * * * * * The second part of the _System of Ethics_, by IMANUEL HERMANN (not Johann Gottlieb) FICHTE, has recently appeared. The anticipations awakened by the first historico-critical part of the work do not appear to be satisfactorily realized by this second dogmatic division. * * * * *
