Detached postscript that discusses the margins of the two photographs, which seem to show that all planets are in the near hemisphere.

Is returning March heliographs. Discusses the appearance of the spots. Has not received the April heliographs.

ES has been forwarded letter explaining why 'great telescope' at Melbourne will not work and suggesting construction corrections, on which JH, who believes such 'a priori condemnation' unjustified, comments herein.

Thanks for his pamphlet on 'Trade Unions and the Cost of Labour.' Comments on this.

Discusses her theory of aerolites and the zodiacal light. Used to visit his house at Slough.

Thanks for his letter about her theory regarding aerolites. Has another query on this question.

Inquires about other sunspot observations made by JH.

Has written to Kew Observatory to send on the photographs.

Has just learnt that some negatives were sent to his former place of residence. Will forward them when he goes to the City. A vote has been made from the Donation Fund of the R.S.L. for six copies of the Kew Solar negatives.

Asks AD's advice on an application JH received the previous day. Comments on JH's health.

JH's letter lays terrible responsibilities at his door. Should not neglect the offer. Regarding the Julian calendar.

Is publishing photographic volume of eminent scientists. Lists twelve. Would like to include JH.

Thanks WH for materials WH sent, including information about scientific activity in Vienna and papers on meteorites. Recounts some of the history of the Analytical Society. Discusses meteorites and also Homeric references to iron.

Suggests reasons for doubting the distribution of bright stars that RP had reported. Responds to RP's query concerning a statement in Outlines Ast. Encourages RP's hypothesizing on star distribution.

Reports on his studies of stellar and nebular distributions, discussing especially whether the Magellanic Clouds show a relation to the Milky Way stars. Speculates on whether recent studies on meteors bear on stellar formation and change. Stresses need for statistical studies in stellar astronomy.

Sends map from his new atlas. Reports finding a region rich in bright stars in the northern hemisphere but distinct from the Milky Way. States that in a Royal Institution lecture, he will claim that telescopes cannot reach the limits of the sidereal system and that it is far more complex than traditionally assumed.

Sends two of his publications, one on terrestrial magnetism at Berlin. Comments on the results, and wonders if JH would enlist the help of the B.A.A.S. to finance further studies by H. J. R. Petersen.

JDH writes that he is glad to hear of Sir William Turner Thiselton-Dyer's [WTTD's] appointment to the Dublin chair [of the Royal College of Science for Ireland, Dublin]. Has seen Dr [Edward Percival] Wright who is happy for WTTD to have access to, & make use of, the T[rinity] C[ollege] Herbarium. However, Wright wishes WTTD to wait a little before taking a more prominent position than himself so that 'matters will arrange themselves'. Wright is talking of getting leave for 2 years & going abroad, leaving WTTD in charge. JDH says that the vegetable products museum should be attached to the Botanic Garden, along with a Herbarium & Library, without which the garden will be useless. JDH cannot supply structural specimens of plants from the RBG Kew museum as all duplicates are sent to places which give things in return. Will be happy to give advice about Cape Flora & thinks it is a worthy endeavour to finish it. Notes that WTTD will probably not be ready to embark on the descriptive part of the flora, & therefore need the herbarium, before Wright leaves anyway.
