C. A. Young—Observations of the Transit of Venus. 323 
6. M. McNeill, Instructor in Astronomy. His instrument 
Was an equatorial mounted on a post in the open air. Aper- 
ture 4 inches; reflecting eye-piece with power of 162. 
7. Professor W. Libbey, Jr. Portable equatorial of 8 inches 
aperture ; reflecting eye-piece and power of 96. 
8. W. F. Magie, Instructor in Physics. He used the finder 
of the 94-inch equatorial. Aperture 8 inches; reflecting eye- 
piece and power of 124. 
. Crew, Fellow of the College. His instrament was an 
altazimuth of 3 inches aperture, reflecting eye-piece, power 80. 
10. H. L. Baldwin, student. Altazimuth of 8 inches aper- 
ture, with reflecting eye-piece and power of 80. 
, 4n addition to these observers, two squads of students, eleven 
Mall, observed images of the sun thrown upon screens by a 
9inch Newtonian reflector and a 54-inch comet seeker. The 
results, however, are hardly satisfactory enough to be given 
here, though they will be published in another connection at 
Some future time. 
At South Hadley, the third and fourth contacts were observed 
by Mr. R. F. West, a graduate student of astronomy in Prince- 
ton, who was sent (by the liberality of Professor Libbey), to 
Utilize the fine instruments o Bilvike Seminary, an insti- 
tation with which the writer has been long connected as a lec- 
turer, The telescope is an 8-inch equatorial by Clark. The 
whole aperture was used, with a reflecting eye-piece and mag- 
nifying power of 175. 
The local time at South Hadley was determined by transit- 
‘ustrument observations on Dec. 6th and 7th, and the approxl- 
Mate longitude by time-signals received at the telegraph office 
om Cambridge on Dec. 5th and 6th, and compared with the 
resulting longitude is doubtful by the amount of one second at 
least, and possibly two. The latitude was determined by the 
niter a year ago, by the zenith telescope met od 
For three or four weeks before the T'ransit all the observers 
had practiced with an artificial transit as opportunity offered.
