error on p. 75, which I beg leave to acknowl- 
edge. By neglecting differential refraction in 
the determination of the value of a revolution 
of a micrometer screw (in the second of the 
three methods proposed) an error of about one 
part in 3,600 is introduced. That is, if the 
value of a revolution is 18/’’, the effect of ne- 
glected refraction is 0/7 .005. 
Again, by a slip of the pen, p. 43, the author 
is made to say that ‘‘ Jn all cases the refraction 
must be applied first.’? There isone exception 
that, in altitudes measured from the sea horizon, 
the correction for dip should be applied previ- 
ous to the correction for refraction. 
My statement concerning the surveyor’s 
transit, that the time, latitude and azimuth 
‘can easily be determined to an accuracy 
within the least readings of the circle’’ is the 
literal truth, so far as the methods given by me 
are concerned. I have not attempted to get 
everything possible out of the surveyor’s tran- 
sit, and why should I? If great accuracy is 
required, instruments and methods specially 
adapted to the solution of the problem, and de- 
scribed in the earlier chapters of the book, will 
be employed. Why should an astronomer 
make a fad of a surveyor’s transit when he has 
an observatory full of instruments which will 
‘do his work better? No further explanation is 
needed for the reviewer’s remark that the sur- 
veyor’s transit ‘has been strangely neglected 
by astronomers.’ W. W. CAMPBELL. 
The reviewer, after careful consideration of 
Professor Campbell’s remarks printed above, 
finds no reason to modify any of the opinions 
expressed in the review. Gan: 
FOEHN WINDS. 
To THE EDITOR OF SCIENCE: In connection 
with Professor Wilson’s communication on 
Foehn Winds in ScIENCE for August 18th, I beg 
to say that the word foehn was misspelled foehm 
in the proof sent me from the publication office 
of this JouRNAL. I made the necessary cor- 
rections in the proof, but for some reason the 
final m was left standing, instead of being re- 
placed by then. Being away from Cambridge at 
the time, I did not notice the mistake in the final 
printing of my note (in SCIENCE for July 21st) 
until a few days ago, and hence it happened that

necessary correction. R. DEC. WARD.
