test 2
75 the Andromeda galaxy, like the Milky Way, is orbited by several companion galaxies but contains about as twice many stars.

78 found in wild woods and stony places, the canterbury bell never flowering until the second (and final) summer of its life.
"flowering" should be "flowers" or "flower"? maybe becasue "bell" is singular, it should be right to use "flowers"? but it is behind "never". i really do not know which is correct.
