es　to　which　they　carried　their　ever…welcome　aid　and　sympathy。

One　whom　we　have　lost；　very　widely　known　and　honored；　was　a　leading　practitioner　of　this　city。　　His　image　can　hardly　be　dimmed　in　your　recollection；　as　he　stood　before　you　only　three　years　ago；　filling　the　same　place　with　which　I　am　now　honored。　　To　speak　of　him　at　all　worthily；　would　be　to　write　the　history　of　professional　success；　won　without　special　aid　at　starting；　by　toil；　patience；　good　sense；　pure　character；　and　pleasing　manners；　won　in　a　straight　uphill　ascent；　without　one　breathing…space　until　he　sat　down；　not　to　rest；　but　to　die。　　If　prayers　could　have　shielded　him　from　the　stroke；　if　love　could　have　drawn　forth　the　weapon；　and　skill　could　have　healed　the　wound；　this　passing　tribute　might　have　been　left　to　other　lips　and　to　another　generation。

Let　us　hope　that　our　dead　have　at　last　found　that　rest　which　neither　summer　nor　winter；　nor　day　nor　night；　had　granted　to　their　unending　earthly　labors！　　And　let　us　remember　that　our　duties　to　our　brethren　do　not　cease　when　they　become　unable　to　share　our　toils；　or　leave　behind　them　in　want　and　woe　those　whom　their　labor　had　supported。　　It　is　honorable　to　the　Profession　that　it　has　organized　an　Association　a　for　the　relief　of　its　suffering　members　and　their　families；　it　owes　this　tribute　to　the　ill…rewarded　industry　and　sacrifices　of　its　less　fortunate　brothers　who　wear　out　health　and　life　in　the　service　of　humanity。　　I　have　great　pleasure　in　referring　to　this　excellent　movement；　which　gives　our　liberal　profession　a　chance　to　show　its　liberality；　and　serves　to　unite　us　all；　the　successful　and　those　whom　fortune　has　cast　down；　in　the　bonds　of　a　true　brotherhood。

A　medical　man；　as　he　goes　about　his　daily　business　after　twenty　years　of　practice；　is　apt　to　suppose　that　he　treats　his　patients　according　to　the　teachings　of　his　experience。　　No　doubt　this　is　true　to　some　extent；　to　what　extent　depending　much　on　the　qualities　of　the　individual。　　But　it　is　easy　to　prove　that　the　prescriptions　of　even　wise　physicians　are　very　commonly　founded　on　something　quite　different　from　experience。　　Experience　must　be　based　on　the　permanent　facts　of　nature。　　But　a　glance　at　the　prevalent　modes　of　treatment　of　any　two　successive　generations　will　show　that　there　is　a　changeable　as　well　as　a　permanent　element　in　the　art　of　healing；　not　merely　changeable　as　diseases　vary；　or　as　new　remedies　are　introduced；　but　changeable　by　the　going　out　of　fashion　of　special　remedies；　by　the　decadence　of　a　popular　theory　from　which　their　fitness　was　deduced；　or　other　cause　not　more　significant。　　There　is　no　reason　to　suppose　that　the　present　time　is　essentially　different　in　this　respect　from　any　other。　　Much；　therefore；　which　is　now　very　commonly　considered　to　be　the　result　of　experience；　will　be　recognized　in　the　next；　or　in　some　succeeding　generation；　as　no　such　result　at　all；　but　as　a　foregone　conclusion；　based　on　some　prevalent　belief　or　fashion　of　the　time。

There　are；　of　course；　in　every　calling；　those　who　go　about　the　work　of　the　day　before　them；　doing　it　according　to　the　rules　of　their　craft；　and　asking　no　questions　of　the　past　or　of　the　future；　or　of　the　aim　and　end　to　which　their　special　labor　is　contributing。　　These　often　consider　and　call　themselves　practical　men。　　They　pull　the　oars　of　society；　and　have　no　leisure　to　watch　the　currents　running　this　or　that　way；　let　theorists　and　philosophers　attend　to　them。　　In　the　mean　time；　however；　these　currents　are　carrying　the　practical　men；　too；　and　all　their　work　may　be　thrown　away；　and　worse　than　thrown　away；　if　they　do　not　take　knowledge　of　them　and　get　out　of　the　wrong　ones　and　into　the　right　ones　as　soon　as　they　may。　　Sir　Edward　Parry　and　his　party　were　going　straight　towards　the　pole　in　one　of　their　arctic　expeditions；　travelling　at　the　rate　of　ten　miles　a　day。　　But　the　ice　over　which　they　travelled　was　drifting　straight　towards　the　equator；　at　the　rate　of　twelve　miles　a　day；　and　yet　no　man　among　them　would　have　known　that　he　was　travelling　two　miles　a　day　backward　unless　he　had　lifted　his　eyes　from　the　track　in　which　he　was　plodding。　　It　is　not　only　going　backward　that　the　plain　practical　workman　is　liable　to；　if　he　will　not　look　up　and　look　around；　he　may　go　forward　to　ends　he　little　dreams　of。　　It　is　a　simple　business　for　a　mason　to　build　up　a　niche　in　a　wall；　but　what　if；　a　hundred　years　afterwards　when　the　wall　is　torn　down；　the　skeleton　of　a　murdered　man　drop　out　of　the　niche？　　It　was　a　plain　practical　piece　of　carpentry　for　a　Jewish　artisan　to　fit　two　pieces　of　timber　together　according　to　the　legal　pattern　in　the　time　of　Pontius　Pilate；　he　asked　no　questions；　perhaps；　but　we　know　what　burden　the　cross　bore　on　the　morrow！　　And　so；　with　subtler　tools　than　trowels　or　axes；　the　statesman　who　works　in　policy　without　principle；　the　theologian　who　works　in　forms　without　a　soul；　the　physician　who；　calling　himself　a　practical　man；　refuses　to　recognize　the　larger　laws　which　govern　his　changing　practice；　may　all　find　that　they　have　been　building　truth　into　the　wall；　and　hanging　humanity　upon　the　cross。

The　truth　is；　that　medicine；　professedly　founded　on　observation；　is　as　sensitive　to　outside　influences；　political；　religious；　philosophical；　imaginative；　as　is　the　barometer　to　the　changes　of　atmospheric　density。　　Theoretically　it　ought　to　go　on　its　own　straightforward　inductive　path；　without　regard　to　changes　of　government　or　to　fluctuations　of　public　opinion。　　But　look　a　moment　while　I　clash　a　few　facts　together；　and　see　if　some　sparks　do　not　reveal　by　their　light　a　closer　relation　between　the　Medical　Sciences　and　the　conditions　of　Society　and　the　general　thought　of　the　time；　than　would　at　first　be　suspected。

Look　at　Vesalius；　the　contemporary　of　Luther。　　Who　can　fail　to　see　one　common　spirit　in　the　radical　ecclesiastic　and　the　reforming　court…physician？　　Both　still　to　some　extent　under　the　dominion　of　the　letter：　Luther　holding　to　the　real　presence；　Vesalius　actually　causing　to　be　drawn　and　engraved　two　muscles　which　he　knew　were　not　found　in　the　human　subject；　because　they　had　been　described　by　Galen；　from　dissections　of　the　lower　animals。　　Both　breaking　through　old　traditions　in　the　search　of　truth；　one；　knife　in　hand；　at　the　risk　of　life　and　reputation；　the　other　at　the　risk　of　fire　and　fagot；　with　that　mightier　weapon　which　all　the　devils　could　not　silence；　though　they　had　been　thicker　than　the　tiles　on　the　house…tops。　　How　much　the　physician　of　the　Catholic　Charles　V。　had　in　common　with　the　great　religious　destructive；　may　be　guessed　by　the　relish　with　which　he　tells　the　story　how　certain　Pavian　students　exhumed　the　body　of　an　〃elegans　scortum；〃　or　lovely　dame　of　ill　repute；　the　favorite　of　a　monk　of　the　order　of　St。　Anthony；　who　does　not　seem　to　have　resisted　temptation　so　well　as　the　founder　of　his　order。　　We　have　always　ranked　the　physician　Rabelais　among　the　early　reformers；　but　I　do　not　know　that　Vesalius　has　ever　been　thanked　for　his　hit　at　the　morals　of　the　religious　orders；　or　for　turning　to　the　good　of　science　what　was　intended　for　the　〃benefit　of　clergy。〃

Our　unfortunate　medical　brother；　Michael　Servetus；　the　spiritual　patient　to　whom　the　theological　moxa　was　applied　over　the　entire　surface　for　the　cure　of　his　heresy；　came　very　near　anticipating　Harvey。　　The　same　quickened　thought　of　the　time　which　led　him　to　dispute　the　dogma　of　the　Church；　opened　his　mind　to　the　facts　which　contradicted　the　dogmas　of　the　Faculty。
