I may mention here the process which I adopt in examining 

 Stephanoeeros. I take an ordinary glass slip and place the object 

 with a small quantity of water in the centre. I then shred some 

 blotting-paper very thin, cut three small squares and place them at 

 different intervals round the fluid, but taking care not to let the 

 blotting-paper touch the fluid, or else the object will be drawn 

 towards it by capillary attraction. I usually wet the blotting- 

 paper, previous to putting it on the slip. I mention this as I 

 have lost some valuable specimens through inadvertence. I then 

 place the cover-glass over the object, letting it rest on the edges 

 of the blotting-paper; and as the fluid evaporates it is easily 

 renewed by wetting the edges of the paper. I find twice in 

 twenty-four hours quite sufficient. The process is very simple and 

 inexpensive, and I have found it answer better than the usual live- 

 box or compressorium. I have kept Stephanoeeros alive thus for 

 ten and twelve days, and have watched its progress from the ovum 

 to maturity. What is important to any one whose means are 

 limited, it is inexpensive, and very convenient. I keep it covered, 

 when not under observation, with a small watch-glass.
