As all the shells had gradually augmented, so was this larger than the others. The extended limbs would have occupied a circle of four inches diameter. About a month after this exuviation the animal perished accidentally, having been two years and eight months under examination. It was an interesting specimen, extremely tame and tranquil, always coming to the side of the vessel as I approached, and holding up its little claws as if supplicating food." The shrimp when in confinement becomes very tame, and readily exuviates. The process is frequent, the integument separates entire, and is almost colorless. In female crustaceans the roe is placed outside the shell to which it adheres. During the period of such adherence, the female crab, so far as observation goes, does not change its shell--a marked provision of nature to preserve the spawn. We may remark that other classes of animals exuviate in a similar manner to the crustaceans. Thus serpents throw off in entire masses their scaly coverings, even a slough from the eyes; and various insects in their larva state are continually throwing off and renewing their skins. FROM GOLD TO GRAY. Golden curls, profusely shed O'er the lovely childish head-- Sunshine, caught from summer skies, Surely here entangled lies: Tossing to the light winds free, Radiant clusters, what are ye? Types of Time that ripples now In bright wavelets o'er the brow-- Of the hopes and feelings blest Dancing in the guileless breast, Beautiful in their unrest: Sparkling joys and willing faith Rising to love's lightest breath;-- Of the future, seeming fair, That may darken with the hair. What are ye, dark waving bands That, beneath the maiden's hands, Sweep around her graceful head? Fold o'er fold of changeful shade Touch the cheek's contrasted bloom With the poetry of gloom. Offerings for a lover's eye; Emblems of Love's witchery, Round her heart that richly lies-- Shadows, while it beautifies; Keepsakes Love delights to give. Did each friend one tress receive, Every shining tress were lost, For the maiden had a host. Ay! but trouble, stories say, Locks as rich hath worn away. What of this? But _friends_ grew spare As the scant and falling hair! Wherefore send your pallid ray, Streaks of cold, untimely gray, Through the locks whose burnish'd hue Hath but seen of years a few? Autumn leaves on summer trees Were less sorrowful than these. Portions of life's travel-soil; Footprints left by Grief and Toil; Relics, too, of watchings late, When one curl was too much weight On the hot brows, bending o'er Some grave book of ancient lore. 'Tis the mourning Nature wears For the hopes of younger years; And the scorching breath of care Thus can fade the brightest hair.
