Claparède

p. 601— no canal in trunk for saliva

[Earthworms, p. 42: "Claparède doubts whether saliva is secreted by worms: see 'Zeitschrift für wissenschaft. Zoologie,' B. xix. 1869, p. 601."]

602 from structure of muscles of trunk judges that it is folded for sucking. (add after describing this agree with inference from structure)

p. 603 3 pairs of lime-secreting glands— — the first the largest, often with rhombs of carbonate of lime.— when single in size even up to 1 1/2 mm.

604. The 2 succeeding pairs of glands considerably smaller Morren says they disappear in winter — (agrees with what we saw in one case Nov. 17th — yet really prob.—

Claparède says he knows nothing about pretended disappearance — The fluid calc-milk milk-like fluid — made of spheres fr 2 to mmm. in diameter —not dissolved in ether, but are so by acetic acid with effervescence— did not otherwise test them.—

Only by exceptions are there crystallize masses in these 2 post. pairs. Agrees with what I once saw.

605 — The glands are not hollow sack, but solid diverticula of the œsophagus, formed formed of glandular follicles — (agrees with results of slow solution)

p 606 — thinks implies that chalk-milk may form the concretions in the œsophagus, but admits that nothing is known or possibly that the calc-milk may be regurgitated into these anterior receptacles & these form the concretions—

He does not seem to think that they are found in the anterior glands. — For these anterior organs are not glandular. but are lined with epithelium with cilia [illeg] (may not these brought the calc-milk into the sacks)
