Ipromisedfractions。Heretheyare。LetusconsidertheTarantulaandtheEpeiraonwhomtheCalicurgihavejustoperated。Thefirstthrustofthestingisdeliveredinthemouth。Inbothvictimsthepoison-fangsareabsolutelylifeless:ticklingwithabitofstrawneveroncesucceedsinmakingthemopen。Ontheotherhand,thepalpi,theirverynearneighbours,theiradjunctsasitwere,possesstheircustomarymobility。Withoutanyprevioustouches,theykeeponmovingforweeks。Inenteringthemouththestingdidnotreachthecervicalganglia,orsuddendeathwouldhaveensuedandweshouldhavebeforeoureyescorpseswhichwouldgobadinafewdays,insteadoffreshcarcasesinwhichtracesofliferemainmanifestforalongtime。Thecephalicnerve-centreshavebeenspared。
Whatiswoundedthen,toprocurethisprofoundinertiaofthepoison-fangs?
Iregretthatmyanatomicalknowledgeleavesmeundecidedonthispoint。

Iinsistuponthispoint。Despitetheirextremedelicacy,thesetwofilamentsmustbeinjureddirectly;for,ifitwereenoughforthestingtoinjectitspoison“thereorthereabouts,“thenervesofthepalpi,soclosetothefirst,wouldundergothesameintoxicationastheadjacentregionandwouldleavethoseappendagesmotionless。Thepalpimove;theyretaintheirmobilityforaconsiderableperiod;theactionofthepoison,therefore,isevidentlysituatedinthenervesofthefangs。Therearetwoofthesenerve-filaments,veryfine,verydifficulttodiscover,evenbytheprofessionalanatomist。TheCalicurgushastoreachthemoneaftertheother,tomoistenthemwithherpoison,possiblytotransfixthem,inanycasetooperateupontheminaveryrestrictedmanner;sothatthediffusionofthevirusmaynotinvolvetheadjoiningparts。Theextremedelicacyofthissurgeryexplainswhytheweaponremainsinthemouthsolong;thepointofthestingisseekingandeventuallyfindsthetinyfractionofamillimetrewherethepoisonistoact。Thisiswhatwelearnfromthemovementsofthepalpiclosetothemotionlessfangs;theytellusthattheCalicurgiarevivisectorsofalarmingaccuracy。

Ideclaremoreover,that,toprovokelightningparalysis,thepoison,ifitisnotdepositedinsidethemassofnervoussubstance,mustactfromsomewhereverynear。ThisassertionismerelyechoingwhattheTwo-bandedScoliahasjustshownus:herCetonia-grub,stunglessthanamillimetrefromtheregularspot,didnotbecomemotionlessuntilnextday。Thereisnodoubt,judgingbythisinstance,thattheeffectofthevirusspreadsinalldirectionswithinaradiusofsomeextent;butthisdiffusionisnotenoughfortheoperator,whorequiresforheregg,whichissoontobelaid,absolutesafetyfromtheveryfirst。

Everythingjustifiesusinbelievingthat,forthesedecisiveinoculations,thestingseeksoutthecorrespondingganglionandactsonlywhenitfindsitunderitspoint。Ontheabdomenthispeculiarinsistenceceases;thestingpassesswiftlyfromonesegmenttoanother。Forthesesegments,whicharelessdangerous,theAmmophilaperhapsreliesonthediffusionofhervenom;inanycase,theinjections,thoughhastilyadministered,donotdivergefromaclosevicinityoftheganglia,fortheirfieldofactionisverylimited,asisprovedbythenumberofinoculationsnecessarytoinducecompletetorpor,or,moresimply,bythefollowingexample。
