THE LYMPHATIC GLANDS. 243 



In the "Tollwuthabteilung of the Institut fuer Infections- 

 krankheiten," in Berlin, the subdural and the intra-muscular 

 inoculations are used exclusively, sometimes both methods are 

 used at the same time. (Beck). 



Differential diagnosis. Beck calls attention to the fact that 

 material obtained from dogs affected with the nervous form of dis- 

 temper will produce paralysis of the hind parts of rabbits that have 

 been inoculated. In these cases the paralysis is not confined to 

 the posterior extremities, but extends to the bladder and rectum. 

 Rabbits thus affected become soiled with feces and urine. This 

 affection cannot be transmitted to a second generation of rabbits. 



14. The Lymphatic Glands. 



The intermaxillary lymphatic glands of horses are always 

 subjected to an examination in diseases of the respiratory ap- 

 paratus. Otherwise they are subjected to special exam- 

 inations only when infectious diseases, glanders and 

 tuberculosis, constitutional blood diseases (leuce- 

 m i a ) or the presence of malignant tumors ( carcinoma 

 and sarcoma) are suspected. Examination consists in 

 palpation (conducted according to the rules given on p. 21). 

 The correct interpretation of these changes was discussed 

 under "intermaxillary lymphatic glands." 



When an examination is called for, the following lym- 

 phatic glands must be considered: 



1. Intermaxillary lymphatic glands, lym- 

 pho glandula submaxillaris. In the ox these are of 

 the size of half a walnut and are situated on the median side of the 

 submaxilla, near its border and in the region of the point of in- 

 sertion of the muse, sterno-maxillaris. 



2 A Lymphatic glands of the parotid region, 

 lymphoglandula parotideae. These are between and 

 below the lobules of the parotid gland. In the ox they have the 

 shape of a flattened tongue and a length approaching 6cm.; this 

 gland projects from beneath the border of the parotid gland, below 

 the maxillary articulation. 



3. The superior cervical glands lympho 

 glandula cervicales superiores, and retro- 

 pharyngeales are situated, as the name implies, on the pos- 

 terior wall of the pharynx. In the ox they consist of a closely 

 united packet, about 5cm. long, under the lateral processes of the 

 atlas, where they can be felt by placing the thumb on the lateral
