DR. WEBSTER ON CHOLERA.
THIS is a calm and rational inquiry into the nature of the extra- ordinary malady which has lately afflicted the nations. Dr. WEB- srrER is a Non-contagionist ; but at the same time, examines the evidence and weighs the nature of it on both sides, with impar- tiality and perspicuity. The peculiar merit of the work is the caution with which the author admits the testimony of alleged facts. Persons who are aware how difficult it is to get at the truth through hearsay, and talk, and prejudice, and interest, will appreciate the author's difficulty on this point. The manner in Which the defects in chains of evidence, relative to histories of the disease in especial cases, are pointed oat, would alone confer consi- derable value upon Dr. WEDSTEles essay.
