Contexto:
Está hablando de cómo la larva del gusano de seda se envuelve en un hilo fino que produce. La frase completa es la siguiente:
"Once again we have to take the simile of the spider’s light filmy substance that comes out not from without but from within the spider’s body, or the cocoon or a silky case as is spun
by a larva from fine threads of its own making, to protect itself as a chrysalis especially as a silkworm;wherewith we in course of time prepare all sorts of silken garments of so many designs and colours, to cover our nakedness and take delight to stunt in borrowed
clothings".
