64 STATEMEJfT AND EXPOSITION OF 



A midnight band with parallel edges. The figure seems to indicate that the 

 band was about 7° or 8° wide. The appearance is such as it might be if the light 

 were reflected at all but right angles to the girdle. 



Evening of April 4, and also that of April 5, 1858; two and one days, respectively, 

 before the last quarter of the moon. 



In the evening of April 5, the light is expressly noted as being visible " entirely 

 across the heavens, from Aries at least to Libra." 



Evening of Oct. 27, 1858; nearly one day before the last quarter of the moon. 



The light seems to have, consistently, been short but considerably bright. 



Both characteristics are more distinctly manifest, in the evening of Oct. 28, 1858 ; 

 day of the last quarter of the moon. 



Evening of Dec. 28, 1858; about 2 days after the last quarter of the moon. 



Light short and rounded at the top, and the base very broad. 



Evening of Jan. 15, 1860 ; 1 day after the last quarter of the moon. 



Light described as having been "intensely bright;" and, in the drawing, it 

 tapers rapidly. 



(91) Among the Notes on the Zodiacal Light, by Eev. Samuel J. Johnson {Pro- 

 ceedings of Royal Ast. Societij for March, 1874), we find— "What Humboldt speaks 

 of as the 'mild pyramidally-shaped zodiacal light, very visible to the unassisted eye' 

 has been displayed liere" (at Upon Helions Rectory, Crediton) " this winter with 

 far more distinctness than I have noticed since Feb. 21, 1870, when I witnessed a 

 vivid appearance of the phenomenon from Lytham, on the Lancashire coast. It 

 was conspicuous, amongst other nights, on February 8, when the impression that 

 Tycho mistook the light for the ' abnormal vernal evening twilight,' appeared at 

 first sight almost pardonable." 



This seems again to present an example of our Case 5th. 



" Feb. 16. Sky clear for a brief interval about 8 P. M. The conical figure 

 very fairly defined, except at the apex, where the curvature was somewhat difiicult 

 to make out. Mars, situated nearly on the axis; about which point the light seemed 

 equal in brightness to that portion of the Milky Way that passes through Cassio- 

 peia. Near the horizon the intensity was decidedly greater, v Ceti appeared just 

 outside the cone of light ; the head of Aries faintly involved in it ; it could be 

 traced, though with difficulty, 3° or 4° above the Pleiwles." 



Again, a remarkable example of our Case \st. For this was the day of the New 

 Moon, and the moon was 1\ day from the Perigee. Confirmed this is withal by 

 the next observation. 



" Feb. 18. Could be readily followed before the moon set Clear extent 



at the base 30° to 35°. Not quite so brilliant as on the 16th; I fancied a slight 

 reddish tinge in the brighter portions." 



Appropriately descriptive of our Case 2d. 



" March 6. The Zodiacal Light again conspicuous. In extent and general 

 features unaltered ; in intensity scarcely so great. The clearest defined portion lay 

 between v Ceti and y Arietis ; at lower altitudes the light, although brighter, 

 appeared very much difli"used. Mars about 5° left of the axis."
