| The spectrum of omicron Ceti contains many very bright lines, and a large proportion of the variable stars are of this type. |
| One of the most interesting of variable stars is that known as omicron Ceti, whose period of change is about 331 days. |
| Another very interesting class of variables is known as the omicron Ceti type. |
| The space between this letter and the omicron is apparently uninscribed, presumably because of the defect in the stone. |
| Later, a letter omega was created for the long value, with O, known as omicron, kept for the short value. |
| I have not read them regularly through, but sufficiently to observe that they are much indebted to omicron. |
