tolerable heat, with the absence of any nourishing food or 

 suitable lodgings, with mosquitoes, with Jacares and wild 

 Indians. If you consult a physician, lie gives you a good 

 supply of quinine, and tells you to take a dose every other 

 day as a preventive against fever and chills ; so that if you 

 escape intermittent fever you are at least sure of being poi- 

 soned by a remedy which, if administered incautiously, may 

 cause a disease worse than the one it cures. It will take

 may be made with as much ease as a reasonable traveller 

 has a right to expect, though of course not without some 

 privations, and also with no more exposure to sickness than

 on the beach at night have given place to the prosaic con- 

 veniences of the steamboat. It is no doubt true of the 

 Amazons, as of other tropical regions, that a long residence
