Note 117 — Chapter XII
Reading edition
The openings of the hepatic diverticula through the sacks lined with thread cells are described by Hancock and Embleton, Ann. and Mag. of Nat. History, Vol. XV. 1845, p. 82. Von Jhering has also recently described these openings (Zool. Anzeiger, No. 23) and apparently attributes their discovery to himself.
