Shelley, let us say in the connection, is a light, and Swinburne is a sound--Browning alone is a temperature.
I think that is a mighty fine way of putting things. It makes me want to be a temperature too, with its associations of temper, temperament, tempered. To be a temperature is to touch the whole skin, and through the skin, to get under it, and not just appeal to the eyes or ears. It is to be a whole climate.
