本文报道的实验是在三种不同的鱼上进行的，即异斜眼底鱼、鲫鱼和星云鲫鱼，它们的侧线系统不同。鳉鱼没有管道，但每个感觉器官在鳞片上都是自由的，骨板上有一个孔，允许神经和毛细血管进入该器官。金鱼的系统属于通常的硬骨鱼类型，即包围感觉器官的通道。不存在辅助侧线器官，但味蕾遍布整个身体（Herrick，'03）。鲶鱼有一条典型的含有感觉器官的运河。此外，味蕾和辅助侧线感觉器官的分布广泛且相当普遍。后者从来没有封闭在运河中，而是通过坑向表面开放（Herrick，'01）。 Harrison ('03) 和 Stone ('22,'33) 已经表明，两栖类的侧线器官源自外胚层基板，该基板在早期阶段受到遗传限制。为了测试鱼的侧线原基是否存在类似的遗传限制，对眼底胚胎进行了一系列手术。听前和听后原基在首次出现时和稍后阶段被去除。一般来说，即使皮基已被去除，侧线感觉器官也是在胚胎发育时形成的。
The experiments reported in this paper have been performed upon three different fish, Fundulus heteroclitus, Carassius auratus and Ameiurus nebulosus, the lateral-line systems of which differ. In the killifish there is no canal but each sense organ is borne free on the scale, a foramen in the bony plate admitting nerve and capillaries to the organ. In the goldfish, the system is of the, usual teleost type, a canal enclosing the sense organs. No accessory lateral-line organs are present but taste buds occur all over the bddy (Herrick,'03). In the catfish there is a typical canal containing sense organs. In addition there is a wide and rather general distribution of both taste buds and accessory lateral-line sense organs. The latter are never enclosed in canals, but open to the surface by pits (Herrick,'01). Harrison ('03) and Stone ('22,'33) have shown that the lateral-line organs in Amphibia arise from ectodermal placodes which are genetically restricted at an early stage. To test whether similar genetic restriction occurs in the lateralline primordia of the fish, a series of operations were performed on Fundulus embryos. Preauditory and postauditory primordia were removed at the time of their first appearance and at slightly later stages. In general, lateral-line sense organs were formed as the embryo developed even though the ppimordia had been removed.
