This was not yet open to both orders. The Ogulnii accordingly gave notice of a measure providing that as there were at that time four augurs and four pontiffs, and it had been decided that the number of

priests should be augmented, the four additional pontiffs and five augurs should all be co-opted from the plebs How the college of augurs could have been reduced to four, except by the death of two of their number, I am unable to discover.

For it was a settled rule amongst the augurs that their number was bound to consist of threes, so that the three ancient tribes of the Ramnes, Titienses, and Luceres might each have their own augur, or if more were needed, the same number should be added for each. This was the principle on which they proceeded when by adding five to four the number was made up to nine, so that three were assigned to each tribe.

But the co-optation of the additional priests from the plebs created almost as much indignation amongst the patricians as when they saw the consulship made open.
