When I brought out the companion work to this, on the Elephant, an ingenious critic rated me soundly because I had not detailed information on diseases of the mighty pachyderm comparable on even terms with our knowledge of the surgery and medicine of the horse, ox, and man. That critic will have lots of scope in scarifying me over this book, for Cameline Pathology is sadly in arrears and the English in India, the Russians in Central Asia, the French in Algeria, and the Arabs in North Africa and South-Western Asia are but slowly accumulating exact knowledge of diseases of the Camel. Had I chosen to bring pure theory to bear I might have posed as a grand promoter, indeed as the originator, of Cameline Pathology and have given a full and elaborate account for correction hereafter by practical observers. Such has not been my object; I have aimed at "holding a mirror up to nature," and have painted Cameline Pathology "with all its warts for I believe that by making the utmost of what we do know, by systematic arrangement, and by scientific expression I best prepare the subject for future advances. It is no slight step forward when we learn our ignorance of a science!
