在动物学的教学中,都要用淡水变形虫做为实驗的材料。可是,采集变形虫和培养变形虫都比较麻煩,至于純粹变形虫的培养,一般在显微鏡下进行分离,如果技术掌握不好,費时较多,不合教学的亟切需要。我們用自然水洋菜制成培养基,来分离淡水变形虫,并利用小球藻,进行培养,經过数次試驗,效果甚好。玆将方法介紹如下: (一)材料試管、棉花(未脫脂)、白金耳,烧杯、滴 In zoology teaching, freshwater amoeba should be used as experimental materials. However, collecting amoeba and cultivating amoeba are more troublesome, as pure amoeba cultivation, generally under the microscope for separation, if the technology is not good, more time-consuming, non-teaching the urgent need. We use natural aquatic plants made of medium, to separate fresh water amoeba, and the use of chlorella, culture, after several tests, the effect is very good. The method will be introduced as follows: (a) material test tube, cotton (non-fat), platinum ear, beaker, drop
