James Edward Preston Muddock, The Sunless City — Chapter XVII (1905)
“ Perhaps no opinion I have ever advanced had incurred more opposition than that of there being inhabitants on the outside of the earth. I am sorry to say that this opposition has not always come from the lower classes, but persons who by position and learning ought to have known better have been pleased to contradict my theories --- theories that were only arrived at after profound research and anxious thought. I have ever stoutly maintained the possibility of the existence of being differently constituted from ourselves, and greatly inferior in mental and physical organisation. ”
