easier detected by percussion.” The author also confirms this 
statement. Roder prefers to make the examinations in the open 
air, rather than in the stable. Ellinger claims that his experi¬ 
ence has taught him a more practical way in this procedure. 
And as nothing is mentioned about it in the text-books of clin¬ 
ical examining methods, as it is also unknown to most young 
practitioners, the author describes his procedure in the following 
way, accompanied by an illustration : For examinations by this 
method, two assistants are required. One of them takes the 
place to the right side of the animal, which is tied, and takes 
hold of the two horns. The other assistant takes hold of the 
lower jaw, with both hands, in such a way that all the fingers 
of both hands, with the exception of the thumb, are arranged 
so that they span the lower jaw, while the thumb of. each hand 
is placed on the nostrils, which are then closed and opened, 
according to the desire of the examiner. By this method the 
examination can be extended as long as necessary, and the 
respiration can be interrupted for longer or shorter periods. 
Examination, therefore, can be made very accurate. This pro¬ 
cedure is particularly suitable for testing caverns, tumors, con¬ 
solidation of tissue in the lungs, adhesions of the pulmonary 
pleura with the costal pleura, which very frequently exist in
