How is Dr. Knowles described in the novel, Margret Howth: A Story of To-Day?

Dr. Knowles, principal owner of the weaving mill, is described as old and obese, "overgrown, looking like a huge misshapen mass of flesh," and has a face that "repelled most men: dominant, restless, flushing into red gusts of passion, a small intolerant eye, half hidden in folds of yellow fat."
