Blue emissions of the Wolf-Rayet type then became occasionally prominent, in remarkable correspondence with the varying lustre of the star; finally, a band at Lambda 3969, found by Wright at Lick to characterise nebular spectra, assumed abnormal importance; and in July the nebular transformation might be said to be complete. Striking alterations of colour attended these spectral vicissitudes.
The star lambda in Orion's head presents an easy conquest for the three-inch, as it consists of a light-yellow star of magnitude three and a half and a reddish companion of the sixth magnitude; distance 4", p. 43°. There is also a twelfth-magnitude star at 27", p. 183°, and a tenth or eleventh magnitude one at 149", p. 278°. These are tests for the five-inch, and we must not be disappointed if we do not succeed in seeing the smaller one even with that aperture.
«§ 361. En avant de ce rocher, du coté l'est, on en voit un autre d'une structure très remarquable. Il a la forme d'un chevron aigu ou d'un lambda [Greek: L]. on le nomme, sans doute
An interesting variable, of the type of Algol, is lambda, which at maximum is of magnitude three and four tenths and at minimum of magnitude four and two tenths. Its period from one maximum to the next is about three days and twenty-three hours, but the actual changes occupy only about ten hours, and it loses light more swiftly than it regains it.
I bade him write down that ‘ὁ νοῦς ἐστιν αὐλός.’ He said that he would do so, and went home, while I stepped over to the pyramids. But my conscience smote me for having uttered a truth, even to aid a friend, and hastening back to Athens, I arrived behind the philosopher’s chair as he was inditing the ‘αυλός.’ “Giving the lambda a fillip with my finger, I turned it upside down.
Here am I, the Professor, a man who has lived long enough to have plucked the flowers of life and come to the berries, which are not always sad-colored, but sometimes golden-hued as the crocus of April, or rosy-cheeked as the damask of June; a man who staggered against books as a baby, and will totter against them, if he lives to decrepitude; with a brain as full of tingling thoughts, such as they are, as a limb which we call "asleep," because it is so particularly awake, is of pricking points; presenting a key-board of nerve-pulps, not as yet tanned or ossified, to the finger-touch of all outward agencies; knowing something of the filmy threads of this web of life in which we insects buzz awhile, waiting for the gray old spider to come along; contented enough with daily realities, but twirling on his finger the key of a private Bedlam of ideals; in knowledge feeding with the fox oftener than with the stork, loving better the breadth of a fertilizing inundation than the depth of a narrow artesian well; finding nothing too small for his contemplation in the markings of the grammatophora subtilissima, and nothing too large in the movement of the solar system towards the star Lambda of the constellation Hercules; and the question is, whether there is anything left for me, the Professor, to suck out of creation, after my lively friend has had his straw in the bunghole of the Universe!
The magnitudes of the components of gamma are four and four and a half, or, according to Hall, both four; distance 8.5", p. 180°. A few degrees above gamma, passing by beta, is a wide double lambda, magnitudes five and eight, distance 37", p. 45°, colors white and lilac or violet.
