** (@. 338.) »It is remarkable that within the area of Ihe 

 trapezium no nebula exists. The brighter porlion of the nebula 

 immediately adjacent to the trapezium, forming Ihe Square front 

 of the head, is shown with the 18-inch rcflcctor broken up 

 into masses, whose motlled and curdiing light evidenlly indi- 

 cales by a sort of granulär texture its consisting of stars; and 

 when examined under (he great light of Lord Rosse's reflector 

 er the exquisite detining power of ihe great achromatic at Cam- 

 bridge, U. S. , is evidentiy perceived to consist of cluslering 

 Stars. There can Iherelore be little doubt as to the whole con- 

 sisting of Stars, too minute to be discerned individually even 

 with the powerl'ul aids, but which become visible as points of 

 light when closely adjacent in the more crowdcd parts.« (Out-

 Trapezium, but no suspicion of a star« (Mem. of the Am er,

 »that a person is immediately madc aware of its having risen 

 abovc Ihe horizon, though he should not be at the time look-

 the atmosphere, resembling the ctTect of the young moon.«
