Letter from Philip Lutley Sclater, to George Gabriel Stokes, regarding a paper 'On fossil remains of equines from central and South America referable to Equus conversidens, Ow., Equus tan, Ow., and Equus arcidens, Ow' by Richard Owen Apologises for not being able to referee the paper, as it deals with a subject on which the referee has 'paid no sort of attention'. Suggests the paper be referred to someone who is 'engaged in the study of extinct Mammalia'. Subject: Zoology, Palaeontology [Published in the Philosophical Transactions of the Royal Society] 23 March 1869
