Referee's report by William Henry Lang, on a paper 'A petrified Williamsonia from Scotland' by Albert Charles Seward Sectional Committee: Botany Recommended for publication in the 'Philosophical Transactions of the Royal Society'. Has not had chance to consult the literature before writing the report, and does not feel confident in offering an opinion on the theoretical portion of the paper. The description is excellent and provides an advance on previous knowledge. The description might be condensed due to the fragmentary nature of the specimen. Has seen some of the specimens on which the paper is based. [Published in the Philosophical Transactions of the Royal Society, 1913] Endorsed on verso as received 9 July 1912. [July 1912]
