== Some Potential Edits == 

 I would first like to commend you on the job well done for this article on John Ray! I was looking it over and I would just like to suggest some possible edits to make it even better.  
 First I'd like to say that in general, the lead section is good as it is clear and understandable and I feel it does a good job of outlining different subjects that he published work in and mentioning the significance of his career. However, I feel there are some pieces of information about his life in general that could be added to the introduction. For example, the introduction does not specify where John Ray was born or include information about his life in general. Although the introduction is not supposed to go into detail about his life, I feel it is lacking any background information of John Ray. Also, I personally do not see the last sentence of the first paragraph as a relevant detail to the introduction. It is an interesting fact that I believe should be mentioned later in the article when more of the detailed facts are being mentioned. 
 The structure overall is good as it includes several heading with subtopics. However, it only includes two images and I believe the inclusion of more images could benefit the article overall. I also think this article could benefit from a “See Also” section that would include links to other relevant articles that the reader may be interested in. The “Notes” section is also rather short and perhaps it could be expanded to further add to the content of the page and give the reader a more thorough understanding of this topic.  
 Although I think this article covers some sections very well, there are others that seem to be rather brief and could be elaborated on. The section that talks about John Ray’s career is extremely long in comparison to the other parts of the article. While I think this is a sub topic that has a lot of information, I still feel other sections should be elaborated on as the coverage seems to be a bit unbalanced. For example, the sections on John Ray’s later life and family as well as his definition of species are very short sections. The section that discusses Ray’s definition of species doesn’t really elaborate on it at all. It includes a quote saying what the definition is but doesn’t say anything else. I think this section could be elaborated on and include some writing and paraphrasing of what the definition is as opposed to just a quote.  
 This article includes neutral coverage as it mostly covers facts about what happened in his life and what he accomplished. Perhaps the article could be improved if there was a section added that talked about the way different people viewed his ideas and perhaps some criticism as the facts included can make it look like John Ray didn’t run into any skeptics along the way.  
 This article has a good amount of references relative to its length and appears to have many reliable sources. The only thing is that the “Other Sources” section is a little short and could benefit from including some more secondary sources to get an array of viewpoints.
