The slugs, well cleared of their mucus, are to be placed in any 

 one of the above media, in small cylindrical glass tubes and 

 tightly sealed, so as not to admit air. This sealing can be done 

 by means of tightly fitting corks, subsequently covered over with 

 a coating of Brunswick black, or by the use of glass tops cemented 

 down with a mixture of old guttapercha, five parts, and asphalt, 

 four parts, melted together and applied hot. 



In concluding this chapter, I would strongly advise you not to 

 go to the expense of buying cabinets wherein to lodge your shells. 

 Rather purchase large books on the subject with your money. 

 Cardboard trays are all that is needed for storage purposes. In 

 them lay the shells on cotton-wool, with a label bearing the date 

 of capture and the locality, also the specific and — if a variety — 

 the varietal name, but these are not so important as the locality, 

 for the shells carry their own identification with them.
