On the general Form of the Thymus Gland in the Foetal Calf. The Thymus Gland of this animal is composed of a thoracic portion of an isthmus of a cervical ])art and of two cornua. The Gland reaches from the anterior mediastinum above the pericardium, to the angle of the lower jaw, extending by its cornua on each side of the neck, and, at the angle of the inferior maxillary bone it doubles upon itself, so that its length is thus somewhat increased. In describing the situation of this organ and of its diflferent parts, I shall suppose the animal lying on its back. The thoracic portion of the Thymus is placed under the upper part of the sternum, and it is generally somewhat in- clined to the left side. It is situated in the anterior medias- tinum, and consequently has the pleura placed upon its sides as it is reflected from the cartilages of the ribs to the peri- cardium. 0](https://iiif.wellcomecollection.org/image/b21300367_0016.jp2/full/800%2C/0/default.jpg)
