My dear Sir

I have long wished that the Intellectual Observer, which I have edited from its beginning, should publish some of your important papers on natural history subjects.1

I have not ventured to ask you before before, because I feared that from health & occupation you might not be able to accede to the request, but let me assure you that if at any time, it would be convenient to publish portions of your researches in a scientific magazine, I should be much obliged by your letting me have them for the I. O2

Permit me also to say that as Hon Sec of the Royal Microscopical Society, that any paper from you on points of minute structure would be highly appreciated by that body.3

I remain | My dear Sir | Yours faithfully | Henry. J. Slack

Charles Darwin Esq FRS | &c &c

The Intellectual Observer, established in 1862, was one of the most popular science periodicals in Britain during the 1860s, appealing to a young and well-educated readership (Ellegard 1957, p. 29). Its contributors included William Bernhard Tegetmeier and Alfred Russel Wallace (see Correspondence vols. 11 and 12, and this volume, letter to A. R. Wallace, 6 July [1867]).
CD did not contribute an article to the Intellectual Observer.
The Royal Microscopical Society published the Quarterly Journal of Microscopical Science. CD never contributed an article.
