C. H. F. Peters—Observations upon the latest Planetoids. 291 
fathom-lines.* The drift of icebergs, as marked by dots on the 
small corner-map, shows the source of the material of the 
banks’ 
rowth of the continent is now most actively going forward. 
t is also evident that the shallowness of the Strait of Belle Isie, 
which prevents the passage of any but the smallest icebergs, is 
the principal means of preventing the filling up of the deep 
channel of the Gulf of St. Lawrence with the sediment now 
dropped on the ‘‘ banks.” 
I shall be under deep obligations to all who will be so kind 
as to furnish exact data for corrections to be made in future 
editions of the chart.

H. F. Perers. [From a letter to one of the Editors, dated 
Litchfield Observatory of Hamilton College, Clinton, N. Y.,

As the moonlight now for some days is interfering with 
observing the small planets, I communicate of the observations 
hitherto obtained the first and last positions of each, omitting 
for brevity’s sake the intermediate ones, The dates of discov- 
ery and the names proposed of these new additions to the group 
are the following : 
Ne) Loreley, 10°7 magnitude, discovered Aug. 9. 
166) Rhodope, 11:2 magnitude, discovered Aug. 15. 
167) Urda, 12 magnitude, discovered Aug. 28.
