56 COMPLETE INSTRUCTION IN 



When it remains perfectly clear, the worms are 

 preserved. This will require several days. 



After the worms are dead, and before they get 

 hard and stiff, they should be carefully taken 

 out with nippers onto a glass slab or plate and 

 straightened out, and it is best then to inflate 

 with a hypodermic syringe, using some of the 

 same fluid the worms- are in. This process will 

 enlarge the worms, as well as harden the internal 

 organs. The syringe may be inserted in the 

 anus, but great care must be taken not to 

 puncture the internal organs. After this is done, 

 they should be at once put back into the fluid. 



ARRANGEMENT FOR A CASE. 



To prepare worms for a case for exhibition, 

 have ready as many sets of bottles (five consti- 

 tutes a full set) as you require. The bottles 

 should be such as are used by naturalists, i. e., 

 without necks. The largest should be 4^ inches 

 long, the others gradually receding in length to 

 the smallest, If inches. The corks must always 

 be the best, and not more than a half-inch deep. 

 A very appropriate finish for the cork is made by 

 splitting cocoons in several layers. Then cut 

 circles just the size of the corks, and glue them 

 onto the corks. Put one worm of the fifth age in 

 the largest bottle, and one of the fourth age in
