Referee's report by Henri Milne Edwards, on a paper 'Researches on the structure and homology of the reproductive organs of the annelids' by Thomas Williams Recommended for publication in Philosophical Transactions. Some of the results seem insufficiently established. There is currently not a lot of existing work on the subject, so publication would be positive. Writing style of the paper could be re-worked. All drawings don't need to be published - only important ones should be kept. Encourages the author to write more slowly to ensure less mistakes. Subject: Zoology [Published in Philosophical Transactions, 1858]. 16 April 1857
