.. .//- VTiM compliments of Dr, Agorastes. AMPHIOXUSANDASGIDIAN OUR GELATINOQS ANCESTORS. EoTT the misidng links were discovered and made known. Imitated from the German of M.

Sc, etc., and to the ■; learned President and Members of the Canadian Institute, Toronto, ^. ■* By DR. PHIL. AGORASTES. A lancelet (Am- phiosus lanceo- iatus) finds it pleasant on Posilippo's shore. Horrid advent of an anatomist A slimy lancelet once lay Half-hidden in the golden sand Of Naples' blue and balmy bay — And thought — hoW pleasant, here, to-day Is Posilippo's strand. But on the horizon's shadowy brim A horrid vision doth arise — A spectacled Professor grim ! All things that creep, crawl, fly, or swim, Must he anatomize! #■ C4) The lancelet captured, and pronounced a vertebrate. The lancelet's objectiona to thia view. The Profeaaor'a answer. A deed of horror. Reault of investigations. A "find" his eager senses sniff — He stoops — he sees: with joy elate He grasps the creature in ^. jiff — And cries — now, I'll be jiggered — if It isn't vertebrate! The victim groan'd — "Come, that's too pale- Don't try on me that precious cram — Limpid and soft from top to tail, I'm nothing but a naked snail — Ask Pallas* what I am 1 " The horrid "Zoo" made answer, "nay! I mean, my dear, myself to 'fix' it: No wise man trusts what others say, Or heeds, in this far-searching day, The dead Past's ipse dixit:" So saying, without more ado, (To tender feeling sadly callous) He slit poor Slimy through and through, And bottled— as he'd bottle you — This pseudo-snail of Pallas ! And thus, although the little nata- Torial beast has no backbone, For reasons based on larval data It came among the Vertebrata A place, at last, to own ! ♦ A celebrated German naturalist of the last centunr, who first described the lancelet in 177*. *»«1 regarded it as a kind of slug. The vertebraie nature of the animal, based on the presence of a chorda dorsalis.was fir^t shewn by Corda.in 1834; *nd its relations to the larval condition of certain tnnicates or ascidlans, by Kowalewslgf in i8«6. It is now commonly looked upon as the lowest type of the tish series. II. Another Professor I A good " bag. " The great news. Heckel on the move. The miaffag links. Pass thirty years and two — Ah me!
