Referee's report by Walter Holbrook Gaskell, on a paper 'On the changes produced in the circulation and respiration by increase of the intra-cranial pressure or tension' by Walter Spencer and Victor Alexander Haden Horsley Recommended for publication in the 'Philosophical Transactions of the Royal Society'. The description and interpretation of the curves should be made with more care. The evidence is not strong. The paper however is still a strong one due to what it suggests. Subject: Physiology [Published in the Philosophical Transactions of the Royal Society, 1891] nd [1890]
