JDH writes about the very bad health of [John] Smith, Curator of the Royal Botanic Gardens, Kew, whose doctors, Paget & Walshe, say he has a heart condition. Attacks of the illness often render Smith completely immobile, he has palpitations & severe pain. JDH goes on to give his own medical opinion that Smith has worsening heart disease but for Smith's state of mind it would be better not to have it officially diagnosed. JDH has not seen much of the British Association for the Advancement of Science [48th meeting, Dublin, Ireland]. However, he has sent Sir William Turner Thiselton-Dyer[WTTD] [William] Spottiswoode's address & [William Henry] Flower's paper on the Linnaean classification of mammals. JDH did not hear [Thomas Henry] Huxley's address as he spent the day with [Alexander] Moore, the Gardener at Glasnevin; where JDH admired the collection of tree ferns & the conifers. JDH has met Suringar & the man WTTD corresponds with about Sinapis glauca. [Alexander] Dickson, [John Hutton?] Balfour & [James] Britten all refused botanical visitors. JDH will take Flower's place at the Botany & Zoology section. Tickets to lectures at the Royal Dublin Society wer sold out to townspeople before any of the delegates arrived. The geologists' section has been quarrelling & 'set upon [William] Pengelly'. An afternoon given by the Lord Lieutenant, John Spencer-Churchill, at Vice Regal Lodge was ruined by bad weather. [John] Sadler has not turned up. JDH criticises the House of Commons office for printing the [Annual RBG Kew?] Report from an uncorrected copy. JDH has asked his son Charles Paget Hooker to visit his Aunt, & will probably send him to Edinburgh. JDH intends to go next to Killarney.
