Progress of Astronomy during the Year 1879. 4:79 
nomical subjects, which appears in Nature in the course of a year, 
and most of which are totally forgotten a month after they have 
been printed. If the editor could see his way to collect reprints 
of all such notes, letters, &c., from time to time in separate 
volumes, he would render good service to Astronomy, even a 
systematical index of five or ten volumes at a time would be very 
useful. The Observatory gives, every month, editorial notes on 
recent publications, which it would be pleasant to see enlarged, 
even if this would have to be done at the expense of the monthly 
double stars and meteors, so very uninteresting to the majority of 
readers. 
16. Observatories. 
In his review of the progress of Astronomy in 1878 (Annual 
Record of Science and Industry), Professor E. 8. Holden has 
collected reports from all the American Observatories, public and 
private. As each report contains a list of all the instruments of 
each Observatory, the whole series gives a very good picture of the 
state of practical Astronomy in the United States. Abstracts are 
also given of the reports in the Monthly Notices, and the 
“ Vierteljahrsschrift der astronomischen Gesellschaft.” It is Pro- 
fessor Holden’s intention in future, to continue these Observatory 
reports in the Report of the Smithsonian Institution. 
Mr. A. A. Common, has mounted his new 36-inch silver-on- 
glass equatorial at Ealing, near London. It is described in “The 
Observatory,” III, p. 167, and Mr. Calver has given a very full 
account of the process of figuring and silvering the mirror in the 
M. N. for November. 
A new observatory has been founded at Kalocza in Hungary, 
by Cardinal Archbishop Haynald. Dr. Charles Braun is the 
Director, and the chief instrument is a seven-inch refractor by 
Merz. 
Another private observatory has been constructed at Plonsk, 
about thirty-seven miles from Warsaw, by Dr. Jedrzejevicz, 
The principal instrument is a 6°4 inch refractor by Steinheil, to be 
used for observations of double stars. 
The new observatory of Queen’s College, Cork, though only 
furnished with comparatively small instruments, promises to 
become one of the most remarkable astronomical institutes exist-
