JDH’s "objection" that small local genera do not vary and mundane ones do, is exactly CD’s point. Local floras useful to test idea that varieties are incipient species. Same genus in different countries cannot be lumped.
Would support the establishment of Colonial magnetic and meteorological observatories if Edward Sabine were to continue to study the observations made [see GA's 1858-1-29].
Summary of JDH’s objections to CD’s survey of floras and conclusion that large genera vary more than small.

Enjoyed visit of Louisa [Herschel Marshall]. Wants copies of JH's new articles. Is witnessing a solar eclipse, in which half the disc was covered, as she writes.
Thanks JDH for his objections; will respond by sending fair copy of MS when written.
Carrington will be communicating with JH regarding Ignatio Porro's instruments. Pleased to hear of the projected new edition of JH's Outlines Astr. Is engaged translating D. F. J. Arago's Astronomy. Points out omissions in this work. Comments on the planet Neptune.

Regarding the recent eclipse of the sun. Has not been able to guess all his riddles.
About viewing the solar eclipse, and the many errors in G. B. Airy's Lectures.
Have looked up the deeds and will make a schedule of them.
Recommends Leonard Horner’s "Account of some recent researches near Cairo" for publication in Philosophical Transactions [R. Soc. Lond. 148 (1858): 53–9]. Believes all the details and sections should be published in full because of importance of investigations leading to the conclusion that man has existed in Egypt for over 13000 years.
Discusses the ranges of species in large and small genera; difficulties involved in limiting the discussion to Britain.
Extracts from MS of vol. 4 of HCW’s Cybele Britannica [1847–59] showing the diversity of views on species among botanists.

Expresses his views, generally supportive, on the question of the continuation of magnetic observations at various colonial stations.
