Observations show, however, that the threads are of very short duration since the mucus becomes brittle and easily broken and is eaten by the snail, especially if food particles settle upon it. The following are variations from the process above described in spinning: 1. Instead of the snail taking air, when it reaches the film and then descending in the usual manner as above descr
