open the box after fifteen minutes, and throw over it 20 cc. of ben- 

 zine. Reclose the door of the box and leave it for ten or fifteen 

 minutes longer. Fleas revive from the chloroform used in killing 

 the cat, but they do not revive if benzine is used. 



Do not use the benzine until the cat is completely anaesthetized, 

 for it causes great discomfort.

glass. The dimensions are given in the figure. The base and frame 

 should be grooved for the reception of the glass, and the whole 

 should be put together with screws to permit the renewal of the 

 glass in case of breakage. 



Along one side, near the top, runs a thick brass wii'e, on which 

 slides a curtain, moved by a string. Just above the curtain, when 

 furled, is a hole, which is closed by a cork secured from loss by a 

 string. The leather handle is convenient in lifting and moving the 

 box. 



The cost of the cat-box, including the glass, is about $1.50. 



Almost any close vessel or box will answer for the administra- 

 tion of a fatal dose of chloroform, but for experimental purposes 

 the progress of anaesthesia must be observed.
