claim-galloway-royal-medal-astronomer-1848 recorded Thomas Galloway's 1848 Royal Medal on the strength of the Wikisource Dictionary of National Biography entry alone — Tier 4, and the load-bearing leg of observation-galloway-is-a-third-astronomer-actuary-instance. The Record of the Royal Society of London (3rd ed., 1912) — the Society's own compiled institutional record of its Fellows, medallists, and history, prepared under the supervision of then-President Sir Archibald Geikie — independently confirms the award. Its year-by-year list of Royal Medallists reads, across a page break: "1847. George Fownes. William Robert Grove. 1848. Thomas Galloway. 1848. Charles James Hargreave." Galloway and Hargreave were the two 1848 medallists.

Per the sourcing-floor note on "compiled statistical reference series" (00-meta/specs/sources.md), the Society's own list of its own medallists is treated as Tier 1 for the fact of the award — the institution's record of what it did, not a secondary retelling. It does not name the cited paper or state the citation reason; that detail (a memoir "On the Proper Motion of the Solar System," Philosophical Transactions, vol. 137, 1847, pp. 79–109) still rests on the DNB and the bibliographic record.

This clears the sourcing floor the medal fact previously failed and answers, for the medal specifically, question-verify-galloway-royal-medal-astronomer-primary. The rest of Galloway's RAS office chronology — vice-presidency in 1837 and 1848 above all — is not confirmed by this source and remains open.
