必须看到归纳与演绎不能人为地对立起来。指出“归纳和演绎正如分析和综合一样，是必然相互联系着的。不应当牺牲一个而把另一个捧到天上去”。在此早着先鞭。关于实验与假设之间的关系，在各种都有论述。他在 中山朗立批发SHINHWA继电器SAS-4225A,25A,75~480VAC

布莱克在化学研究中非常实验，而且是个应用定量的研究气体的人，定量研究需要称量，而称量离不开天平。历史资料表明，布莱克确实使用了天平，他用过的天平至今仍保存在爱丁堡皇家博物馆中，下图即是布莱克用过的天平。用绳子挂着称盘，横梁又挂在另一个称钩上。布莱克正是用这个天平进行化学实验研究，而且做出了发现的，这个天平的使用，不仅在化学实验中建立了定量，而且对天平的进一步发展、改良，也是重要的。布莱克之后，英国化学家亨利·卡文迪许也进行过精密的定量实验，据说还曾设计制造过天平，由于卡文迪许本人的生平资料不详，很难确切知道他是何时和如何设计、制造天平的。后来，卡文迪许用过的天平曾在皇家科学院展览。这架天平柜内。中山朗立批发SHINHWA继电器SAS-4225A,25A,75~480VAC
