Letter from Georg Balthasar Neumayer, Frankenthal to Edward Sabine Update on Neymayer’s work. Neumayer asks Sabine if he received his ‘report on the inclination at Hobarton’. Discusses the printing of his [observations]. Refers to the [Austo-Prussian War] which ‘disturbed everything in’ their ‘poor country’. Remarks on Sabine’s request to have Neumayer’s barometrical observations. Refers to the Melbourne observations, the ‘state of the atmosphere’, and ‘radiation according to Professor [John] Tyndall’s theory’. 21 August 1866
