An observer states that in forty-two successive days at the Cape, there were only three in which he could not see Venus in broad daylight. Sir John Herschel assures us that he has written a letter by the light of an eclipse of the moon. Under these circumstances, the starry heavens presented a brilliance, of which the inhabitants of the northern hemisphere can have no conception; the line from Orion to Antinous being remarkably rich and brilliant, and appearing as a continuous blaze of light; with, however, a few patches of the sky destitute of stars. ------------------ INTRODUCTION OF THE POTATO. The history of the potato affords a strong illustration of the influence of authority. For more than two centuries, the use of this invaluable plant was vehemently opposed: at last, Louis XV. wore a bunch of its blossoms in the midst of his courtiers, and the consumption of the root became universal in France. ------------------ FARADAY, AS A LECTURER. Von Raumer acutely observes:--"Mr. Faraday is not only a man of profound chemical and physical science, (which all Europe knows), but a very remarkable lecturer. He speaks with ease and freedom, but not with a gossiping unequal tone, alternately inaudible and bawling, as some very learned professors do; he delivers himself with clearness, precision, and ability. Moreover, he speaks his language in a manner which confirmed me in a secret suspicion I had, that a great number of Englishmen speak it very badly. Why is it that French in the mouth of Mdlle. Mars, German in that of Tieck, and English in that of Faraday, seems a totally different language? Because they articulate what other people swallow or chew. It is a shame that the power and harmony of simple speech (I am not talking of eloquence, but of vowels and consonants), that the tones and inflexions which God has given to the human voice, should be so neglected and abused. And those who think they do them full justice--preachers--generally give us only the long straw of pretended connoisseurs, instead of the chopped straw of the dilettanti." ------------------ THE RAILWAY SYSTEM SUGGESTED.
