在脊椎动物亚門各綱的实驗课和标本制作中,我們对所需用的动物,在解剖前进行处理时,沒有采用文献所介紹的“杀死”方法;而是用形成“气栓”的方法將动物弄死。在血循环器官的着色和血循环系統的显示方面,也沒有用一向所沿用的色液配方注射;而是用非常簡單的“石油色料液”注射。这兩种方法都便于操作,而且效果良好,又由于与一般文献所载方法出入较大,特介紹出來,并请指正。 In the experimental class and specimen preparation of the vertebrate subphylum, we did not use the “kill” method described in the literature for the animals we needed before we dissected them. Instead, we used the “thrombus” The animal killed. In the coloring of the blood circulation organs and the display of the circulatory system, it is not injected with the color liquid formulation which has been used all along; rather, it is injected with a very simple “petroleum color liquid”. Both of these methods are easy to operate and work well, and because of the large discrepancies with the methods contained in the general literature, they are introduced and corrected.
