结果发现七鳃鳗的心脏接受来自迷走神经的纤维，耳廓含有大量的嗜铬细胞-显然与小神经节细胞相同。在Myxine心脏中未观察到此类细胞。在七鳃鳗迷走神经刺激产生强烈的加速度，随后心动过缓。迷走神经、延髓或大血管刺激后，在Myxine心脏中未观察到立即反应。报告的其余部分涉及2个心脏对乙酰胆碱、丁酰胆碱、丙酰胆碱、尼古丁、肾上腺素、去甲肾上腺素和毛果芸香碱的反应。
It was found that the heart of Lampetra receives fibers from the vagus nerve, and the auricle contains numerous chromaffin cells - apparently identical with small ganglion cells. No such cells were seen in Myxine heart. In Lampetra vagal stimulation produces intense acceleration followed by bradycardia. No immediate response was noted in Myxine heart upon vagal, medulla oblongata, or large blood vessel stimulation. The remainder of the report concerns the reaction of the 2 hearts to acetyl-choline, butyrylcholine, propionylcholine, nicotine, epinephrine, nor-epinephrine, and pilocarpine.
