oi- nipple. Tliis test is not usually employed 

 in veterinary practice. 



(5) The intracutaneous or, as it is com- 

 monly called in veterinary practice, the in- 

 tradermal test (Moussu and Mantoux) con- 

 sists in the injection into the skin of suita- 

 bly diluted O. T. or purified tuberculin in 

 doses of 0.1 to 0.2 c.c. The intrapalpebral 

 test, as described by Mohler, consists of the 

 injection of tuberculin into the skin of the 

 lower eyelid and is a modification of the 

 usual intradermal method. 



Relative Sensitiveness of Tesls. 



According to Hamman and Wolman the in- 

 tracutaneous (intradermal) and subcutane- 

 ous local tests are the most delicate we have. 

 They reveal practically the full percentage 

 of tuberculous individuals. 



The same authorities state that according 

 to their sensitiveness the tests are to bt 

 ranked as follows: 



(1) Intracutaneous (intradermaH. 



(2) Subcutaneous (local reaction'*, 

 (o) Cutaneous. 



(4) Subcutaneous (.-systemic reaction'). 



(5) Percutaneous. 



(6) Conjunctival. 



Tuberoiilin. 



Tuberculin is the liquid, usually glyceiin- 

 ated bouillon, on which tubercle bacilli liave 

 grown until it has become saturated with the 

 product of the organisms (Moore). 



DosuKre of Tubereiilin. Subcutanc(ui.< tfst. 

 2-4 I'.c. of diluted tuberculin, each c.c. con- 

 taining 0.12.5 c.c. of O. T. tuberculin. M"hen 

 re-test.s are made within six months the 

 initial dose should be doubled. Horses same 

 as for cattle; goats and sheep, i/^ c.c. Swine, 

 1 c.c. Dogs, 0.1 c.c.
