natives of India had prevented their noticing the existence of the disease until the fact was brought prominently forward by the presence of Europeans. It should also be brought to mind, that cholera asphyxia is not a new disease to these natives, but seems to be, in many places, almost endemical, whilst it is well known that strangers, in such circumstances, become more obnoxious to the disease than the inhabitants of the country. Moreover, travellers have superadded to the remote cause of the disease, fatigue and road discomforts, which are not trifling in a country where there are neither inns nor carriages." (p. 89.) Cholera only attacks a certain proportion of a population, and is it wonderful that we should hear more of epidemic on high roads, where the population is greatest? High roads too are often along the course of rivers; and is there not some reason for believing, that there is often along the course of rivers, whether navigable or not, certain conditions of the atmosphere unfavourable to health? When Dr. Hawkins stated, as we find at p. 131 he has done, that where the inhabitants of certain hilly ranges in India escaped the disease, "these have been said to have interdicted all intercourse with the people below," he should have quoted some respectable authority, for otherwise, should we unhappily be visited by this disease, the people of our plains may one day wage an unjust war against the sturdy Highlanders or Welsh mountaineers.[10] Little do the discussers of politics dream of the high interest of this part of the cholera question, and little can they conceive the unnecessary afflictions which the doctrine of the contagionists are calculated to bring on the nation. Let no part of the public suppose for a moment that this is a question concerning medical men more than it does them; _all_ are _very_ deeply concerned, the heads of families more especially so. [Footnote 9: This is by far the best work yet published in England on the cholera, but it is to be regretted that the author has not alluded to the works of gentlemen who have a priority of claim to some of the opinions he has published: I think that, in particular, Mr. Orton's book, printed in India, should have been noticed.] [Footnote 10: Something of this kind would have infallibly taken place, had certain insane proposals lately made respecting the _shutting in_ of the people of Sunderland, been carried into effect.]
