I　shall　now　mention　a　few　instances　in　which　the　disease　appears　to　have　been　conveyed　by　the　process　of　direct　inoculation。
  Dr。　Campbell　of　Edinburgh　states　that　in　October；　1821；　he　assisted　at　the　post…mortem　examination　of　a　patient　who　died　with　puerperal　fever。　　He　carried　the　pelvic　viscera　in　his　pocket　to　the　class…　room。　　The　same　evening　he　attended　a　woman　in　labor　without　previously　changing　his　clothes；　this　patient　died。　　The　next　morning　he　delivered　a　woman　with　the　forceps；　she　died　also；　and　of　many　others　who　were　seized　with　the　disease　within　a　few　weeks；　three　shared　the　same　fate　in　succession。
  In　June；　1823；　he　assisted　some　of　his　pupils　at　the　autopsy　of　a　case　of　puerperal　fever。　　He　was　unable　to　wash　his　hands　with　proper　care；　for　want　of　the　necessary　accommodations。　　On　getting　home　he　found　that　two　patients　required　his　assistance。　　He　went　without　further　ablution；　or　changing　his　clothes；　both　these　patients　died　with　puerperal　fever。　　This　same　Dr。　Campbell　is　one　of　Dr。　Churchill's　authorities　against　contagion。
  Mr。　Roberton　says　that　in　one　instance　within　his　knowledge　a　practitioner　passed　the　catheter　for　a　patient　with　puerperal　fever　late　in　the　evening；　the　same　night　he　attended　a　lady　who　had　the　symptoms　of　the　disease　on　the　second　day。　　In　another　instance　a　surgeon　was　called　while　in　the　act　of　inspecting　the　body　of　a　woman　who　had　died　of　this　fever；　to　attend　a　labor；　within　forty…eight　hours　this　patient　was　seized　with　the　fever。'
  On　the　16th　of　March；　1831；　a　medical　practitioner　examined　the　body　of　a　woman　who　had　died　a　few　days　after　delivery；　from　puerperal　peritonitis。　　On　the　evening　of　the　17th　he　delivered　a　patient；　who　was　seized　with　puerperal　fever　on　the　19th；　and　died　on　the　24th。　Between　this　period　and　the　6th　of　April；　the　same　practitioner　attended　two　other　patients；　both　of　whom　were　attacked　with　the　same　disease　and　died。
  In　the　autumn　of　1829　a　physician　was　present　at　the　examination　of　a　case　of　puerperal　fever；　dissected　out　the　organs；　and　assisted　in　sewing　up　the　body。　　He　had　scarcely　reached　home　when　he　was　summoned　to　attend　a　young　lady　in　labor。　　In　sixteen　hours　she　was　attacked　with　the　symptoms　of　puerperal　fever；　and　narrowly　escaped　with　her　life。
  In　December；　1830；　a　midwife；　who　had　attended　two　fatal　cases　of　puerperal　fever　at　the　British　Lying…in　Hospital；　examined　a　patient　who　had　just　been　admitted；　to　ascertain　if　labor　had　commenced。　This　patient　remained　two　days　in　the　expectation　that　labor　would　come　on；　when　she　returned　home　and　was　then　suddenly　taken　in　labor　and　delivered　before　she　could　set　out　for　the　hospital。　　She　went　on　favorably　for　two　days；　and　was　then　taken　with　puerperal　fever　and　died　in　thirty…six　hours。
  〃A　young　practitioner；　contrary　to　advice；　examined　the　body　of　a　patient　who　had　died　from　puerperal　fever；　there　was　no　epidemic　at　the　time；　the　case　appeared　to　be　purely　sporadic。　　He　delivered　three　other　women　shortly　afterwards；　they　all　died　with　puerperal　fever；　the　symptoms　of　which　broke　out　very　soon　after　labor。　　The　patients　of　his　colleague　did　well；　except　one；　where　he　assisted　to　remove　some　coagula　from　the　uterus；　she　was　attacked　in　the　same　manner　as　those　whom　he　had　attended；　and　died　also。〃　　The　writer　in　the　〃British　and　Foreign　Medical　Review；〃　from　whom　I　quote　this　statement；and　who　is　no　other　than　Dr。　Rigby；　adds；　〃We　trust　that　this　fact　alone　will　forever　silence　such　doubts；　and　stamp　the　well…　merited　epithet　of　'criminal；'　as　above　quoted；　upon　such　attempts。〃　＇Brit。　　and　For。　　Medical　Review　for　Jan。　　1842；　p。　　112。＇
