out by ciliated cells, but there may be a few non-ciliated cells throughout 

 the whole extent and especially in the isthmus near the uterine ostium. 



The uterus was not found lined by a continuous ciliated epithelium in 

 any animal, and not in man. Ciliated cells were found scattered over the 

 surface, sometimes singly and sometimes in small groups. Apparently 

 only about one cell in 15 or 20 was ciliated. 



Ciliated cells with their cilia were found no more difficult of preserva- 

 tion in isolation preparations and sections from the oviduct and uterus 

 than from other situations, e. g. the trachea. 



HEMOLYMPH GLANDS IN DOMESTIC ANIMALS. By Mb. F. G. White. 

 Department of Histology and Embryology, Cornell University. (Com- 

 municated by Professor Simon H. Gage.) 



Besides verifying the presence, as previously reported, of hemolymph 

 glands in man, horse, ox, sheep, pig and rat, I have also found them in 

 cat, rabbit, red squirrel (Sciurus hudsonicus) and chipmunk (Tamais 

 striatus). In the cat they were found in the cephalic portion of the 

 thorax, near the renal vessels, and in the prevertebral region posterior to 

 the kidneys. Five were examined, in each of which these glands were 

 found. In the rabbit very few occur. From the six examined, hemo- 

 lymph glands were obtained in two cases. In one they were found in 

 the thorax near the carotid arteries, in the other near the vena cava, pos- 

 terior to the kidneys. In a single red squirrel examined these glands 

 were found near the thyroids, in the thorax near the carotid arteries and 

 in the pelvic region. 



In the chipmunk they were found at the branching of the renal ves- 

 sel. Histological examination was made in every case to determine the 

 true nature of the gland. 



In the horse many large hemolymph glands were found in the anterior 

 portion of the thorax, a few between the aorta and dorsal vertebrae, many 

 near the kidneys and a few in the pelvic region and in the mesocolon at 

 its visceral attachment. 



Very little difficulty is experienced in identifying, from the gross ap- 

 pearance, hemolymph glands in ox, sheep and pig, as their dark red color 

 forms a marked contrast to the prevertebral fat in which they are found 

 in large numbers. In man and horse one is less sure in thus identifying 

 them, while in the other animals mentioned it is usually necessary to 

 resort to an histological examination. 



The glands of the horse offer very favorable material for the study of 

 the histology of these structures. For laboratory purposes, however, 

 material is most easily obtained by getting from the butcher the tra-
