B. T. Lowne’s observation [Mon. Microsc. J. 4 (1870): 326–30] that boiling does not kill certain moulds is curious, but then how account for absence of all living things in Pasteur’s experiment?

Always delighted to see a word in favour of Pangenesis.

Thiselton-Dyer’s paper ["On spontaneous generation and evolution", Q. J. Microsc. Sci. 10 (1870): 333–54] is Spencerian.

The chemical conditions for first production of life are said to exist at present, but in some warm little pond today such matter would be absorbed or devoured, which would not have been the case before living creatures were formed.

JDH writes that he is pleased William Thiselton-Dyer is starting work on the Asclepiadoideae [for FLORA CAPENSIS]. The herbarium of Robert Wight will be at Thiselton-Dyer's disposal. William Henry Harvey is a model of how to approach complex systematic work. JDH approves of Thiselton-Dyer's plan to have an educational museum in the [botany] department [of Royal College of Science for Ireland]. Discusses sending Welwitschia specimens for the museum, 2 live specimens have already been sent from RBG Kew to Glasnevin [National Botanic Gardens, Ireland]. JDH will send Thiselton-Dyer Asclepiad flowers as they bloom at RBG Kew & a copy of Benjamin Delessert's ICONES SELECTAE PLANTARUM QUAS IN SYSTEMATE UNIVERSALI with figures by Joseph Decaisne. JDH adds he has not heard from India House about a flora of India, he is concerned about 'the neuralgia' & would like Salix specimens from Dr Moore for Kew's new 'Salicetum'.
