I want to know the answer to the following question:
What friend of Claridge's was helpful in introducing asphalt for use in pavements?
All the background I'm provided with is that "Dr T. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement (in 1836)".". Is that enough to answer the question?
Answer: yes
