In the second type the disease begins with a high fever ; feeding and 

 rumination are suspended ; chills and muscular tremors appear ; the 

 animals are dull and show great weakness ; in the courre of the disease 

 the dullness gives waj- to unecisiness, champing of the jaws, spasms of 

 the limbs, kicking and pawing the ground ; breathing is difficult, nos- 

 trils dilated and mouth open ; nose, mouth, and all visible mucous 

 membranes become bluish ; the animals may moan ; discharges con- 

 tain red mucus or blood ; blood vessels may rupture ; the animal lies 

 down and death closes the scene in two or three days. 



Symptoms of Symptomatic Anthrax, or Black I^eg, differ somewhat. 

 An animal which a short time before appeared strong and vigorous now 

 seems listless ; has a vague expression about the eyes ; the ears become 

 heavy and pendent ; the animal is tender about the loin, ribs, and flank ; 

 pulse irregular, from 80 to 100 per minute ; the animal may be lame in 

 one or more hmbs ; tumors may form about the loin, brisket, head, and 

 neck ; they refuse to move and are unconscious to surrounding objects ; 

 staring eyes ; the tumors contain serosity extravasated blood ; they 

 speedily decompose ; gases are evolved which give rise to a crepitating 

 sound ; they die in a state of coma. Sheep assume the enteric form. 

 The first symptoms are a short step. They will lie down or stand 

 apart from the flock ; head depressed ; back arched ; abdominal pains ; 

 the wool begins to fall out and has a dry appearance. If the disease 

 advances rapidly death is sure. 



Treatment. Curative treatment is out of the question. Only 

 vaccination of healthy animals to check the spread of the disease. 

 Destroy all diseased animals and burn the carcasses. Burn all forage 

 and the sheds where healthy animals may come in contact. Vaccina- 

 tion should be directed by a skilled veterinary that all antiseptic pre- 

 cautions may be adhered to. This consists in making a hypodermic 

 injection of Serum No. x, repeat in five days with Serum No. 2. 

 Treatment of Symptomatic Anthrax, or Black I^eg, is followed up in 

 much the same way by serum especially prepared and injected hypo- 

 dermically, according to the age of the animals and circumstances. 

 One preparation is injected, which suffices in older animals but younger 

 ones should be injected with double vaccine ten days later. 



VERMICULAR BRONCHITIS OF SHEEP. 



A highly infectious disease caused by the strongjdus filaria. This 

 parasite is from one to two and one half inches long. The female is 

 white and larger than the male, which is of a yellowish white color. 

 Its body is of a uniform size but tapered at both ends. The head is 

 short, stumpy, rather angular, but not tuberculated as in other strongy- 

 lus. The anatomical situation of the parasites in the lungs of lambs and 

 sheep is not always the same. In lambs they are found not only in 

 the bronchial tubes but also in the lung substance, while in sheep they 

 are generally encysted in the parenchyma of the lungs, giving them
