Demonstrating Mitosis in Mamnialia.| — Dr. B. Solger recommends 

 the amnion of the rat for demonstrating the mitosis of Mammalia to a 

 class. The freshly cut-out membranes are placed in a saturated aqueous 

 solution of picric acid for twenty-four hours. It is then washed in dis- 

 tilled water previous to immersion in 70 per cent, spirit, the strength of 

 which is to be gradually increased. The preparations are easily stained 

 in five minutes in Ehrlieh's hasmatoxylin, diluted oue-half with distilled 

 water. 



Instead of fixing with picric acid and staining with hsematoxylin, 

 excellent results are obtainable by means of Flemming's mixture and 

 safranin.
