I want to know the answer to the following question:
How did Alexander Macfarlane summarize the relationship between different methods in "A Treatise on Algebra" in his review?
All the background I'm provided with is that "In a separate review, G. B. Mathews wrote, "It possesses a unity of design which is really remarkable, considering the variety of its themes."". Is that enough to answer the question?
Answer: no
