Source of text:
TxU:H/M-0495; Reel 1093
Summary:

Encloses copy of 29 July 1846 letter from G. B. Airy, who refuses to act on any further recommendations from Board of Visitors so long as James South is member of Board. Insinuations by South in R. H. Inglis's motion before House of Commons are deemed malevolent by Airy, who no longer considers South competent to guide scientific inquiry.
