To the planet (199), found on July 9th, as mentioned in the 
ast number of the Journal, I have given the name Byblis. 
gga, as is known, had been searched for in vain for many 
years, though it had come twelve times in opposition since its 
discovery, Nov. 12, 1862. There existed nine observations of 
reflecting power, be it atmospheric or arising from the shape. 
And I find, that, in communicating my observations in 1863 to 
the Astron. Nachr. (No. 1428), I added then the following 
note: “From the mean of the estimates the magnitude of the 
planet in the mean opposition results 18:0, Remarkable is the 
whiteness of the light with which it was shining, and though 
but a luminous point, the image presented a certain neatness. 
This was very striking in comparing it on the same evenings, 
therefore independently of the state of the air, with Ferona, 
which was not far off.” Moreover, in 1864 Professor Tietjen, 
e orally communicated to me, estimated the magnitude 
- much larger than the computation had given it. Frigga, there- 
fore, needs watching, as perhaps it may give us some insight 
ite the physical structure of the planetoids and their atmos- 
eres. 
When it was re-discovered, on J uly 16th, its position differed 
about 6° in right-ascension and 2° in declination from the place 
Q=45,. t= 2°28, log a=—0-4425, 
while for Frigga we have 
QHeA, 1=2°28', log r= 0431, 
therefore quite the same, the apparently larger difference in the 
longitude of the node arising only from the small inclination.
