Cassini regnede Opdagelsen af denne fjerde Stjerne („ag- giunta della quarta Stella alle tre contigue“) til de Forandringer, som Orions-Taagen i sin Tid har lidt. 68 (S. 228.) „It is reinarcable that within the area of the tra- pezium no nebula exists. The brighter portion of the nebula imme- diately adjacent lo the trapezium, forming the square front of the head is shown with the 18—inch reflector broken up into masses, whose mottled and curdling light evidently indicates by a sort of granular texture its consisting of stars; and when examined under the great light of Lord Rosses reflector or the exquisite defining power of the great achromatic at Cambridge, Ü. S., is evidently percehed to consist of clustering stars. There can therefore be little doubt as to the whole consisting of stars, too minute to be discerned individually even with the powerful aids, but which become visible as points of light when closely adjacent in the more crowded parts.“ (Outlines p. 609.) William C. Bond, der anvendte en 23 Fods Refractor, forsynet med et 14 Tommers ObjectiV, siger: „there is a great diminution of light in the interior of the Trapezium , but no suspicion of a star“ (Mem. of the Amer. Acad., new Series Vol. III. p. 93). 69 (S, 228.) Philos.
