Paper, 'The chemistry of the urine of the horse' by Fred [Frederick] Smith Smith writes: 'I have attempted in the following paper to record the results obtained from a series of analyses of the urine of the horse in health. When I first commenced my subject I was under the impression that, with the exception of the following references, the literature of the subject was remarkably bare. It is true that nothing had been done in England, but on the Continent, in Germany in particular, the urine of the horse has received especial consideration. My attention was later called to the following references.' Annotations in pencil and ink. Subject: Chemistry / Biology Received and read 20 June 1889. Communicated by William Aitken. A version of this paper was published in volume 46 of the Proceedings of the Royal Society as 'The chemistry of the urine of the horse'. 1889
