Now add to all this the undisputed fact, that within the walls of lying-in hospitals there is often generated a miasm, palpable as the chlorine used to destroy it, tenacious so as in some cases almost to defy extirpation, deadly in some institutions as the plague; which has killed women in a private hospital of London so fast that they were buried two in one coffin to conceal its horrors; which enabled Tonnelle to record two hundred and twenty-two autopsies at the Maternite of Paris; which has led Dr. Lee to express his deliberate conviction that the loss of life occasioned by these institutions completely defeats the objects of their founders; and out of this train of cumulative evidence, the multiplied groups of cases clustering about individuals, the deadly results of autopsies, the inoculation by fluids from the living patient, the murderous poison of hospitals,--does there not result a conclusion that laughs all sophistry to scorn, and renders all argument an insult? I have had occasion to mention some instances in which there was an apparent relation between puerperal fever and erysipelas. The length to which this paper has extended does not allow me to enter into the consideration of this most important subject. I will only say, that the evidence appears to me altogether satisfactory that some most fatal series of puerperal fever have been produced by an infection originating in the matter or effluvia of erysipelas. In evidence of some connection between the two diseases, I need not go back to the older authors, as Pouteau or Gordon, but will content myself with giving the following references, with their dates; from which it will be seen that the testimony has been constantly coming before the profession for the last few years. “London Cyclopaedia of Practical Medicine,” article Puerperal Fever, 1833. Mr. Ceeley's Account of the Puerperal Fever at Aylesbury. “Lancet,” 1835. Dr. Ramsbotham's Lecture. “London Medical Gazette,” 1835. Mr. Yates Ackerly's Letter in the same Journal, 1838. Mr. Ingleby on Epidemic Puerperal Fever. “Edinburgh Medical and Surgical Journal,” 1838. Mr. Paley's Letter. “London Medical Gazette,” 1839. Remarks at the Medical and Chirurgical Society. “Lancet,” 1840. Dr. Rigby's “System of Midwifery.” 1841. “Nunneley on Erysipelas,”--a work which contains a large number of references on the subject. 1841. “British and Foreign Quarterly Review,” 1842. Dr. S. Jackson of Northumberland, as already quoted from the Summary of the College of Physicians, 1842. And lastly, a startling series of cases by Mr. Storrs of Doncaster, to be found in the “American Journal of the Medical Sciences” for January, 1843.
