[1] After Samuel Rowbotham's death in 1884, Blount became the President of the Universal Zetetic Society, whose objective was "the propagation of knowledge related to Natural Cosmogony in confirmation of the Holy Scriptures, based on practical scientific investigation".

[6] Blount and her husband wanted to provide evidence of the earth's flat surface and they created experiments on the Old Bedford Level Canal over several weeks.

[1] On 11 May 1904, Lady Blount hired a photographer to use a telephoto-lens camera to take a picture from Welney of a large white sheet, which she had placed the bottom edge near the surface of the river at Rowbotham's original position 6 miles (9.7 km) away.

[8] Blount's letter did not discuss the effects of atmospheric refraction but the photographer noted a mirage which he described as "an aqueous shimmering vapour [appearing] to float unevenly on the surface of the canal".

[8] These controversies became a regular feature in the English Mechanic magazine in 1904–05, which published Blount's photo and reported two experiments in 1905 that showed the opposite results.
