〃Very　clean；〃　said　the　house　doctor。　〃Very　clean　and　nice。〃

〃Urn；〃　said　the　doctor　with　the　beard。　The　third　doctor　looked　over　the　house　doctor's　shoulder。

〃Please　move　the　knee；〃　said　the　bearded　doctor。

〃I　can't。〃

〃Test　the　articulation？〃　the　bearded　doctor　questioned。　He　had　a　stripe　beside　the　three　stars　on　his　sleeve。　That　meant　he　was　a　first　captain。

〃Certainly；〃　the　house　doctor　said。　Two　of　them　took　hold　of　my　right　leg　very　gingerly　and　bent　it。

〃That　hurts；〃　I　said。

〃Yes。　Yes。　A　little　further；　doctor。〃

〃That's　enough。　That's　as　far　as　it　goes；〃　I　said。

〃Partial　articulation；〃　said　the　first　captain。　He　straightened　up。　〃May　I　see　the　plates　again；　please；　doctor？〃　The　third　doctor　handed　him　one　of　the　plates。　〃No。　The　left　leg；　please。〃

〃That　is　the　left　leg；　doctor。〃

〃You　are　right。　I　was　looking　from　a　different　angle。〃　He　returned　the　plate。　The　other　plate　he　examined　for　some　time。　〃You　see；　doctor？〃　he　pointed　to　one　of　the　foreign　bodies　which　showed　spherical　and　clear　against　the　light。　They　examined　the　plate　for　some　time。

〃Only　one　thing　I　can　say；〃　the　first　captain　with　the　beard　said。　〃It　is　a　question　of　time。　Three　months；　six　months　probably。〃

〃Certainly　the　synovial　fluid　must　re…form。〃

〃Certainly。　It　is　a　question　of　time。　I　could　not　conscientiously　open　a　knee　like　that　before　the　projectile　was　encysted。〃

〃I　agree　with　you；　doctor
