I spent it in ransacking the library until I discovered a medical book which gave a description of strychnine poisoning.

我把它花在了翻阅图书馆， 直到我发现了一本描述士的宁中毒的医学书籍。

" We are now able to account for the symptoms of strychnine poisoning being so long in making their appearance. A narcotic taken with strychnine will delay the action of the poison for some hours" .

“我们现在能够解释士的宁中毒的症状为何出现这么长时间。与士的宁一起服用的麻醉剂会使毒药的作用延迟几个小时” 。
