The perception of Ireland and India as ‘zones of famine’ led many nineteenth-century observers to draw analogies between these two troublesome parts of the British empire. This article investigates this parallel through the career of James Caird (1816–92), and specifically his interventions in the latter stages of both the Great Irish Famine of 1845–50, and the Indian famines of 1876–9. Caird is best remembered as the joint author of the controversial dissenting minute in the Indian famine commission report of 1880; this article locates the roots of his stance in his previous engagements with Irish policy. Caird's interventions are used to track the trajectory of an evolving ‘Peelite’ position on famine relief, agricultural reconstruction, and land reform between the 1840s and 1880s. Despite some divergences, strong continuities exist between the two interventions – not least concern for the promotion of agricultural entrepreneurship, for actively assisting economic development in ‘backward’ economies, and an acknowledgement of state responsibility for preserving life as an end in itself. Above all in both cases it involved a critique of a laissez-faire dogmatism – whether manifest in the ‘Trevelyanism’ of 1846–50 or the Lytton–Temple system of 1876–9.

A series of ten cis-dihydro-diol metabolites has been obtained by bacterial biotransformation of the corresponding 1,4-disubstituted benzene substrates using Pseudomonas putida UV4, a source of toluene dioxygenase (TDO). Their enantiomeric excess (ee) values have been established using chiral stationary phase HPLC and H-1 NMR spectroscopy. Absolute configurations of the majority of cis-dihydrodiols have been established using stereochemical correlation and X-ray crystallography and the remainder have been tentatively assigned using NMR spectroscopic methods but finally confirmed by circular dichroism (CD) spectroscopy. These configurational assignments support and extend the validity of an empirical model, previously used to predict the preferred stereochemistry of TDO-catalysed cis-dihydroxylation of ten 1,4-disubstituted benzene substrates, to more than twenty-five examples.
