to that of low Auroree Boreales. We could not believe that 

 it was crepuscular, as it was too early, nor that it was of the 

 nature of what are commonly called the " Northern Lights." 

 We watched it for a considerable time, during which it ap- 

 peared to vary in brilliancy. However, it branched out to 

 Regulus, and also towards Coma Berenicis, the edge of low 

 fog, towards the south, being also illuminated. It faded first 

 in the branch towards Coma Berenicis; and, lastly, under the 

 advancing twilight, in that towards Regulus. Gamma Virginis 

 was in the axis, near the horizon, and Kappa Crateris on 

 the azimuthal limits towards the south. From east, through 

 the north to west, stars were visible to the horizon, which 

 but very seldom is the case here. A considerable number of 

 shooting stars were streaming about this morning. Having 

 little doubt that the branch of elliptic light which extended 

 towards Regulus was the zodiacal light, although I had ne- 

 ver before seen it in the morning (and, indeed, in Italy alone 

 in the evenings of the months of March and April), I re- 

 solved to look out again for it. The weather was unpropi- 

 tious until the morning of the 10th, when it was seen from 

 the observatory, at ten minutes before four o'clock, and for 

 some time afterwards, by my assistant, Mr. Magrath. I saw 

 it from my house at a few minutes before five o'clock, when 

 it shewed, with very tolerable definition, the elliptic outline 

 which I have so often remarked in Italy in the spring 

 evenings. There was no trace, on this occasion, of a branch 

 of light towards Coma Berenicis. In less than a quarter of 

 an hour it was almost entirely lost behind a rising fog, 

 which left a sharp white frost upon the ground. The re- 

 markable features of the phenomena we witnessed seem to 

 be these, viz., 1st, that on the morning of the 4th there 

 was a second branch of light, and also an illuminated edge 

 to the fog in horizon ; neither of which were visible on the 

 morning of the 10th, nor have I ever previously observed 

 any thing similar to accompany the evening exhibitions of
