|Title||Unpublished manuscript, 'Attempt to apply instrumental measurement to the zodiacal light' by Charles Piazzi Smyth|
|Date||25 March 1848|
|Description||After describing the manner in which the zodiacal light was first strongly represented to him in South Africa in 1843, and which seemed to imply that some of the received opinions with regard to it were erroneous, Smyth describes an equatorial instrument which he contrived for the purpose of measuring the right ascension and declination of the apex of the light; some instrumental method of determining these data, and thence the principal phenomena of the appearances, being evidently desirable on account of the immense extent to which the judgement may be biased by prejudice or casual circumstances, when the mere senses are trusted to for determining the extent, situation, and character of so faint and vague a body. Followed by eight pages of figures relating to astronomical observations and apparatus.|
