THE STAR- PISH. 



Lesson I. 



Specimens : A dried star-fish and a single dried lay for each 

 child, and a few large star-fishes in alcohol. The single rays 

 shonld he ent open down the back and the contents removed, leav- 

 ing only the sacs eonneoting with the tube-feet. The best way to 

 prepare star-fishes dry is to pnt them into fresh water nntil their 

 bodies become fully rounded, then to soak in alcohol for an hour or 

 two to harden the tissues, and finally to dry in the sun or a moder- 

 ately hot oven. If alcohol is too expensive, they may be pnt into 

 boiling water for a few minutes before drying. But the rays will 

 drop off if they are left in the hot water too long. In this lesson, 

 and the two following, parts are described as they appear on dried 

 specimens.
