Someone's added a comment saying "This article may not meet the general notability guideline. Please help to establish notability by adding reliable, secondary sources about the topic. If notability cannot be established, the article is likely to be merged, redirected, or deleted. (August 2010)"

Could they advise me what more reliable secondary sources than the ones cited (Proceedings of the Royal Society, 1915, B. Vol 89 pp. xv-xx and "David Douglas Cunningham (1843–1914): a biographical profile". Aerobiologia (Springer) 15 (4): 255–258. Dec. 1999) are necessary.
