Show SHELL FISH. Non: XXVII. 74 could not exifl: but for the exertions of the Cancer Pinnotheri s, who li \·es in the fame ihell as a guard and companion. Amren. Acad. Vol. II. P· 48, Lin. Syfl:. N at. Vol. I. p. u 59, and P· I040· The Pi nnothe ris, or P in nophylax, is a fmall crab naked lil e Bernard the H ermit, but is furndhed with good eyes, and li ves in the fame {hell with the Pinna; when they want food the Pinna opens its fh cll, and fends its faithful ally to forage ; but if the Cancer fees the Polypus, he returns fudden1y to the arms of his blind hofl:cfs, who by doling the {bel\ avoids the fury of her enemy; otherwife, when it has proc ured a booty, it brings it to the opening of the fh ell, where it is admitted, and they div ide the prey. This was obferved by HJflcqu ifl: in his voyage to Pal~fl:in e. The By!fus of the antients, according to Arifl:otle, was the beard of the Pinna above mentioned, but feems to have been ufed by other writers indifcr iminately for any fpun material, which was efleemed fin er or more valuable than wool. Reaumur fays the threads of this Byffus are not lefs fine or lefs beautiful than the filk, :~s it is fpun by the filk-worm; the Pinna on the coafls of Italy and Provence (where it is filhed up by iron-hooks fixed on long poles) is called the filk-·worm of the fea. The fl:ockings and gloveli manufatl:urcd from it, are of exquifite finenefs, but too warm for common wear, and are thence efl:eemed ufeful in rheumatifm and gout. DiEt. raifonnc art. Pinnemarine. The warmth of the Byfrus, like that of !ilk, is probably owing to their being bad conducrors of heat, as well as of eletl:ricity. V/hen thefe fibres are broken by violence, this animal as well as the mufcle has the power to reproduce tpem like the common fpiders, as was obferved by M. Adanfon. As raw filk, and raw cobwebs, when [wallowed, are liable to produce great ficknefs, (as I am informed) it is probable the part of mufcles, which fometimes difagrees with the people who eat them, may be this f1lky web, by which they attach themfelves to fl:ones. The large kind of P inna contains fome mother-pearl of a reddi!h tinge, according to M. d'Argenville. The fubltance fold under the name of Indian weed, and ufed at the bottom of fi.lh -lines, is probably a produttion of this kind; which however is fcarcely to be difl:ingui lhed by ~he eye from the tendons of a tat's tail, after they have bee n feparated by putrefaClion 111 water, and well cleaned and rubbed; a produtl:ion, which I was once {hewn as a great curiof1ty; it had the uppermofl bone of the tail adhering to it, and was faid to have been ufed as an ornament in a lady 's hair. 75 .
