ox THE VISIBILITY OF VENUS — CAMERON. 159 



not be made for one of her niornino--star seasons if some one 

 would onl}' take the trouble to turn out in the mornings and 

 make the necessary observations at the beginning and end of the 

 season. 



So far, I have dealt with only one of the two questions that I 

 proposed to treat when lieginning to write, but tlie paper is 

 already longer for the one suljject than I hoped to make it for 

 both. The second — as to the visibility of Venus to the naked 

 eye in daylight — is the more interesting of the two, l)ut it must 

 stand over for the present. I maj^just saj', however, that I have 

 learned from Venus herself that it is not at all a rare or extra- 

 ordinary thing to see her with the eye in broad daylight, and 

 that no keen powers of vision are needed to see her so. On 

 ever}' clear da}' this year so far she could have been seen even 

 at noon by any eye of average quality that knew where to look 

 for her ; and the same sight may be had by the same kind of 

 eye on ever}- clear da}' from now till the end of the year, except- 

 ing only a fortnight or so in Jul}'.
