As the result of a great number of experiments, a distinguished 
continental authority, Ed. Dele, comes to the following con¬ 
clusions :* “ The invasion of pleuro-pneumonia (not easy to re¬ 
cognize) is accompanied by an increase of temperature. This 
continues during the period of increase , and it is at its height at 
the period of acme. From that it declines and indicates the 
period of decline towards recovery (slow diminution) or towards 
death (probably more rapid).” 
Treatment. —Seldom indeed will the enlightened practitioner 
attempt medicinal or curative treatment. One reason for this is 
the danger of keeping infected stock, for generally a case of 
apparent recovery is not a sound animal. 
Dr. Thayer gives the following as a case of supposed recovery: 
“ One-half or two-thirds of the lungs are solidified ; the first effort 
of nature is to throw around the diseased mass a covering of 
fibrinous material, entirely shutting off the healthy from the dis¬ 
eased tissue, which is generally accomplished in from fifteen to 
forty days. Suppuration then commences on the surface of the 
diseased mass, which continues until the whole is liquified ; 
absorption is constantly going on, and in from six to twenty 
months the animal recovers, but with the loss of a portion of the 
vital organ. If the animal is a working bullock, its value is de¬ 
stroyed ; if a cow in milk, after the acute stage is passed, the 
secretion is partly restored, and the milk consumed by the 
people.”! 
If treatment is undertaken in any case, no attempt must be 
made to “ cut short” the course of the disease. Unfavorable 
symptoms may be controlled by medicine, and every attention 
given to hygienic measures. The sick must be carefully segrega* 
ted, have plenty of fresh air “but without producing draughts: 
the skin should be protected by a light rug, which must be suf¬ 
ficiently thin to allow of cutaneous transpiration ; feeding not to 
be thought of in the earlier stages ; ” later, semi-fluid matter, as 
milk, glycerine, and raw eggs may be given in the acute stages, 
cod liver oil and molasses in the convalescent. Brushing: the skin
