188 . Address to a Phrenologist. 
may consult you as our forefathers did a Lilly, or a Dee; but 
superior minds will regard you with a mixture of compassion 
and contempt*. Take counsel, and follow another course ; the 
field of useful knowledge is wide, it is of a rich soil, and yet af- 
fords but a small produce from the want of labourers that are 
willing to abandon altogether toy-making, and the construction 
of ingenious riddles.

* If you be eminent in any branch of human knowledge, beware how 
you engage with phrenology, for the foibles and false steps of superior 
minds are sometimes recollected when their real excellencies are nearly 
forgotten or kept out of sight ; you will find an instance of this in a descrip- 
tion of Merehiston Tower, in a late Number of the “ Provincial Antiquities 
of Scotland.” In that description, those fathers of science, Newton and 
Napier, have their foibles exposed with too free a hand, when it is consi- 
dered that the authority of this popular writer will be gladly seized by men 
who would willingly sink the greatest talents. to the level of their own. The 
writer seems also to be in error when he makes Napier’s bones a name of 
logarithms.

XLII. Tables of the Longitude and Altitude of the Nonagesi- 
mal Degree of the Ecliptic. By Mr. James Urtine. 
To Dr. Tilloch. 
Sir, — I HAVE sent you for insertion in the Philosophical Ma- 
gazine and Journal, a Table of the Longitude and Altitude of the 
Nonagesimal Degree of the Ecliptic. As the finding of the longi- 
tude and altitude of the Nonagesima is an extremely tedious 
operation, I presume the ‘Table I have calculated will be found 
valuable, more particularly as the Tables inserted in the first vo- 
lume of Dr. Maskelyne’s Astronomical Observations made at the 
Royal Observatory at Greenwich, and in Vince’s Astronomy, 
give the longitude and altitude only to within 10 seconds (being 
calculated before Taylor’s Tables of Logarithms were published), 
and moreover contain no correction for the Variation of the 
Obliquity of the Ecliptic, and but a very brief Table of the cor- 
rection necessary to be made for a change of latitude. 
Longitude and Altitude of the Nonagesimal Degree of the 
Ecliptic, for the Latitude of the Royal Observatory at Green- 
wich, 51° 28’ 40 North, or 51° 17’ 48” reduced to the 
Earth’s centre, the Ellipticity of the terrestrial Spheroid being 
1-309th part of the Equatorial_Radii. With the Variations of 
Longitude and Altitude for 100 Minutes of Latitude North of 
Greenwich; and for 100 Seconds Diminution of the Obliquity 
of the Ecliptic. (Obliq. Ecliptic 23° 28’) Calculated from 
~ Taylor’s Tables of Logarithms.
