The distribution of chingger mites is world-wide. Hatori, 1919 first reported the occurrenceof the scrub-typhus and its vector, Trombicula akamushi, in Taiwan Province. It.is predicted thatthe chigger mites must be widely distributed in this country. The writer made a preliminary survey-of the chigger mites in Nanking area in the summer andautumn months of 1955. Out of thirty six different kinds of wild and domestice animals examined,including rats, chickens, etc.,twenty were found to be parasitized by the chigger mites. Specimenscollected were mounted on slides with Puri's fluid. Altogether seven species of the chigger mites were found on the animals examined. They are:Walchia sp., Trombicula sp. 1, T. sp. 2, T. sp. 3, Acomatacarus sp. 1, A. sp. 2, and Neoschon-gastia gallinarum. The latter species has the highest percentage of infection ranging from71.4-97.1% and causes severe damages on domestic fowls.

In this paper, techniques are described for removal and replacing of yolk of eggs of pigeons, hens and ducks, and the effects of the exchange of yolk on growth and other morphological characters on the domestic fowls were studied.When 0.4-3.0 cc. of yolk (13%-88%) of pigeon eggs were replaced by yolk of Rhode Island Red, local black hen or South China Duck, the hatchability was about 60%.When pigeon eggs received more than 1 cc. of yolk from Rhode Island Red, the growth rate was lowered.If the parental...

In this paper, techniques are described for removal and replacing of yolk of eggs of pigeons, hens and ducks, and the effects of the exchange of yolk on growth and other morphological characters on the domestic fowls were studied.When 0.4-3.0 cc. of yolk (13%-88%) of pigeon eggs were replaced by yolk of Rhode Island Red, local black hen or South China Duck, the hatchability was about 60%.When pigeon eggs received more than 1 cc. of yolk from Rhode Island Red, the growth rate was lowered.If the parental pigeons were of the same breed and feather coloration, the exchange of yolk had no effect on the feather coloration of the youngs. But if the parental pigeons were not of the same feather coloration or breed, the exchange of yolk would produce youngs of a slightly darker feather coloration.

(一)本文研究调换卵黄的方法,及调换卵黄对于孵出的鸽、鸡、鸭生长率及性状的影响.(二)用洛岛红鸡,本地黑土鸡及华南鸭的卵黄调换到鸽蛋中,调换量自0.4至3.0毫升(约占鸽蛋卵黄总量的13%至88%).平均孵出率约为61%.(三)如果实验鸽亲本是同色纯种,调换卵黄对于羽色没有产生明显的变异;如果亲本不是同色,多数经调换蛋黄的幼鸽羽色较对照的显得深些. (四)用洛岛红鸡卵黄作调换,超过1毫升的量,一般会使鸽的生长率降低.(五)用2-10毫升(11%-53%)华南鸭、番鸭或澳洲黑鸡卵黄调换到来克亨鸡蛋中,或将4毫升(21%)番鸭或华南鸭卵黄调换到洛岛红鸡蛋中,多数实验组的体重增长较对照组的慢.至于出生至开始产卵日数、每月平均产卵数或卵重等方面没有明显的差异.在形态方面,经调换3-5毫升华南鸭卵黄的来克亨雄鸡表现着性早熟的现象.(六)调换10毫升番鸭卵黄的华南鸭与北京鸭的杂交鸭或调换10毫升华南鸭卵黄的番鸭(雌)与华南鸭(雄)的杂交鸭的体格都是较对照组的小.

1)The sound-conducting apparatus in the middle-ear of domestic fowls includes the membrana tympani,columella,musculus tensor tympani and several ligaments.These or- gans possess a simpler structure than in mammals,and yet their peculiar structures and interconnections between them make it possible to accomplish the conduction of sound waves. 2)The membrana tympani is about 6mm in diameter and forms the dorso- medial wall of the medial end of the external acoustic meatus.The surface of the mem- brane slopes...

1)The sound-conducting apparatus in the middle-ear of domestic fowls includes the membrana tympani,columella,musculus tensor tympani and several ligaments.These or- gans possess a simpler structure than in mammals,and yet their peculiar structures and interconnections between them make it possible to accomplish the conduction of sound waves. 2)The membrana tympani is about 6mm in diameter and forms the dorso- medial wall of the medial end of the external acoustic meatus.The surface of the mem- brane slopes ventro-medially,with the lateral end of the columella attached to its caudo- medial region.The tendon of the tensor muscle is inserted on its lateral surface and pushes its central part outward,producing a concavity of its inner surface. 3)The tensor muscle arises from the ventro-lateral part of the foramen magnum of the occipital bone and ends in a delicate tendon inserting on the lateral surface of the drum membrane where the extracolumella is attached.When the muscle contracts,it draws the drum outward and tenses the membrane,therefore it is better named as tensor tympani externum. 4)The columella,with its shaft directing in an oblique direction,has two special functional characteristics:(a)When the tensor tympani retracts the membrane,the columella changes its oblique angle to compensate the variation in the distance between the drum and the fenestra vestibuli;(b)The oblique position of the columella diminishes the force of the sound waves(push and pull)and avoids damaging the drum membrane. 5)The inner surface of the membrane tympani is concave,and therefrom the ten- sor tympani internum has lost its functional significance to regulate the tension of the drum,and has degenerated into a ligament.This ligament is divided into medial and lateral parts;the medial part is stronger then the lateral. 6)The ligaments of membrana tympani are the drum-tubal and marginal.Liga- ments of the columella are the columello-squamosal and ligament proprium.The columello-squamosal ligament is the most important apparatus to fix the columella,and the crucial point between the columella and ligament is the hinge of the columella move- ment.
