Firstly, oscillation between events of imperial and of local interest, the anticipated diamond jubilee of Queen Victoria (born 1820, acceded 1837) and the posticipated opening of the new municipal fish market:  secondly, apprehension of opposition from extreme circles on the questions of the respective visits of Their Royal Highnesses the duke and duchess of York (real) and of His Majesty King Brian Boru (imaginary):  thirdly, a conflict between professional etiquette and professional emulation concerning the recent erections of the Grand Lyric Hall on Burgh Quay and the Theatre Royal in Hawkins street:  fourthly, distraction resultant from compassion for Nelly Bouverist’s non-intellectual, non-political, non-topical expression of countenance and concupiscence caused by Nelly Bouverist’s revelations of white articles of non-intellectual, non-political, non-topical underclothing while she (Nelly Bouverist) was in the articles:  fifthly, the difficulties of the selection of appropriate music and humorous allusions from everybody’s book of jokes (1000 pages and a laugh in every one):  sixthly, the rhymes, homophonous and cacophonous, associated with the names of the new lord mayor, Daniel Tallon, the new high sheriff, Thomas Pile and the new solicitorgeneral, Dunbar Plunket Barton.

What relation existed between their ages?

16 years before in 1888 when Bloom was of Stephen’s present age Stephen was 6. 16 years after in 1920 when Stephen would be of Bloom’s present age Bloom would be 54.  In 1936 when Bloom would be 70 and Stephen 54 their ages initially in the ratio of 16 to 0 would be as 17 1/2 to 13 1/2, the proportion increasing and the disparity diminishing according as arbitrary future years were added, for if the proportion existing in 1883 had continued immutable, conceiving that to be possible, till then 1904 when Stephen was 22 Bloom would be 374 and in 1920 when Stephen would be 38, as Bloom then was, Bloom would be 646 while in 1952 when Stephen would have attained the maximum postdiluvian age of 70 Bloom, being 1190 years alive having been born in the year 714, would have surpassed by 221 years the maximum antediluvian age, that of Methusalah, 969 years, while, if Stephen would continue to live until he would attain that age in the year 3072 A.D., Bloomwould have been obliged to have been alive 83,300 years, having been obliged to have been born in the year 81,396 B.C.

What events might nullify these calculations?

The cessation of existence of both or either, the inauguration of a new era or calendar, the annihilation of the world and consequent extermination of the human species, inevitable but impredictable.

How many previous encounters proved their preexisting acquaintance?

Two.  The first in the lilacgarden of Matthew Dillon’s house, Medina Villa, Kimmage road, Roundtown, in 1887, in the company of Stephen’s mother, Stephen being then of the age of 5 and reluctant to give his hand in salutation.  The second in the coffeeroom of Breslin’s hotel on a rainy Sunday in the January of 1892, in the company of Stephen’s father and Stephen’s granduncle, Stephen being then 5 years older.
