On 110 preparations of the kidney in some wild animals (hare, fox, wolf, bear, boar and chamois), the blood vessels and the excretory apparatus were studied by dissection, injection-corrosion and microscope. Only the bear has a markedly split kidney, whereas the kidneys of the other animals are unsplit. In the fox there is an obvious split of the renal artery into anterior and posterior branches which supply the anterior and posterior portion, respectively, of the renal parenchyma, being separated from each other, so that we may speak of an anterior and posterior kidney. In the fox, wolf, hare and chamois the interlobar arteries pass through the renal calices in a loop composed of adipose tissue, invested by the epithelium of the renal calyx. The renculi of the bear kidney show complete autonomy in relation to the blood vessels as well as in relation to the excretory apparatus. The relation of the surface of the excretory apparatus to the whole kidney was studied. Thus we have found the fox to have relatively the largest excretory apparatus, whose surface amounts to 31% of the whole kidney. In the remainder of the animals investigated this percentage is considerably less, ranging from 21.7% (boar) to 26.7% (bear).
在对一些野生动物（野兔、狐狸、狼、熊、野猪和羚羊）的110个肾脏标本进行研究时，通过解剖、注射腐蚀法和显微镜观察了其血管和排泄器官。只有熊的肾脏有明显的分裂，而其他动物的肾脏没有分裂。在狐狸中，肾动脉明显分为前支和后支，分别供应肾实质的前部和后部，二者相互分离，因此可以说有一个前肾和一个后肾。在狐狸、狼、野兔和羚羊中，叶间动脉呈环状穿过肾盏，该环由脂肪组织构成，并被肾盏上皮覆盖。熊肾的肾小叶在血管以及排泄器官方面表现出完全的自主性。研究了排泄器官表面与整个肾脏的关系。结果发现，狐狸的排泄器官相对最大，其表面积占整个肾脏的31%。在其余被研究的动物中，这一比例要小得多，从21.7%（野猪）到26.7%（熊）不等。
