Humbert Reagent Set

Definition and scope

The Humbert Reagent Set is a closed assemblage of nine reagent ampoules, one applicator brush, and a bound schedule of permitted pairings, maintained under the standing authority of the Office of Acquisitions & Stasis. It is catalogued as a single object despite containing eleven discrete components, an arrangement that has produced persistent difficulty in the office's own ledgers. The Set is named for the clerk who assembled it, and is held on Floor 214 in a cedar case lined with untreated felt.

The Set's primary function is the application of reagents to prepared surfaces in circumstances where the Reagent Schedule does not reach — that is, where the hour, surface, or reagent pairing has never been enumerated. In such cases the bound schedule within the case is cited as a local authority, subject always to the standing provisions governing Reagent Application.

Composition

The nine ampoules are numbered I through IX in Roman numerals on their stoppers, though the numbering does not correspond to the order of the schedule, and no clerk has ever satisfactorily explained why it should. Three of the nine are in continuous rotation; the remaining six are drawn from the case only when a specific pairing is invoked. Ampoule VI has not been opened since the incident of the winter of 8-402.

"The Set is complete when all nine ampoules are present and unbroken. A Set missing one ampoule is a Set missing one ampoule; it is not a partial Set, and it may not be referred to as such in any register maintained under this office."

— Office of Acquisitions & Stasis, Standing Order 14, Clause 3

The applicator brush is of sable, cut flat, and is replaced on average every eleven months. The replacement brushes are drawn from the same supplier under an arrangement that predates the current Fourteenth Concordance and has not been renegotiated since.

History

The Set was assembled in 7-388 by the clerk Humbert of the Fourth Scriptorium, who had been tasked with resolving a backlog of unpaired reagent requests that had accumulated over three years. The backlog itself was the product of a drafting error in the Reagent Schedule that left a fourteen-hour window each day in which no permitted pairing existed. Humbert's bound schedule was intended as an interim measure; it has been in continuous interim use for two hundred and eleven years.

In 8-402, an application performed under the Set's schedule was contested on the grounds that the schedule had never been formally ratified. The dispute reached the Tenth Concordance, whose Annex D addresses reagent-ledger correspondence in some detail but is silent on the question of local schedules issued by individual clerks. The matter was referred upward and has not returned.

Humbert himself submitted three successive petitions to have the Set renamed after the office rather than after himself, each of which was declined on the grounds that renaming an object in continuous use would require the amendment of every register in which it appears. His fourth petition is recorded as withdrawn.

Contested status

There is disagreement, unresolved in the record, as to whether the Set constitutes a reagent vault for the purposes of inspection. The Office of Acquisitions & Stasis maintains that a vault is a room, and that a cedar case is not a room, regardless of its contents. The Clerks of the Margin have twice attempted to include the case in a routine inspection and were turned away at the door on both occasions, the second time with a note appended to the inspection register reading only "case, not vault."

A minority position, associated with the Functionalist reading of the schedule, holds that the Set should be dissolved and its ampoules returned to the primary vaults, on the grounds that a private schedule held in a felt-lined case is an affront to the principle of a single authority over reagent hours. This position has never commanded a majority but is cited regularly.

Under the Third Concordance, any reagent stored within the Set that meets the definition of a Controlled Atmospheric Reagent remains subject to the same handling provisions as such material held in the primary vaults — a provision that applies, by its terms, to Ampoule VII, whose classification has been disputed since 7-455.

Visiting and access

The case may be consulted on any day except the eighth of the month, when the felt lining is brushed and the ampoules are counted twice. Visitors are permitted to read the bound schedule but not to handle the applicator brush. Two persons may stand at the case at one time; a third is asked to wait in the corridor.
