a pigeon was inoculated from the same culture, and after a short 

 illness it recovered. 



A liealthy })ig' was inoculated at noon 80th March with a pure 

 broth cultivation derived from the mesenteric glands of a pig dead of 

 the disease, and on 2nd April it was very sick, and it was noticed that 

 its breathing was difficult and that it had a cough. It woidd lie about 

 and would only resent being disturbed by a short grunt. It went 

 olf its food, but was enticed to eat with warm pollard and cooked 

 potatoes and milk. At 4.80 p.m. on 1st April its temperature was 

 105'8 deg., and at 10 a.m. on 2nd it was 104 deg., and at 5.o0 p.m. 

 on same evening it rose to 104'4. From 2nd to btli it was getting 

 worse, and its temperature ran a little above 104 deg. On the 6tli 

 the difficulty of breathing and cougli had increased and load moist 

 rattlings in the throat could be heard. From 7th to 1 1th it was much 

 about the same as on 6th. 



On 12th an abscess was noticed in thigh at seat of inoculation. 

 The breathing was still difhcult and moist sounds could be heard. 

 It could not stand long when urged to do so. It would lose the 

 power of the fore legs, sink down upon and crawl about on its knees. 

 Its temperature at 4.80 p.m. on 12th was 104 4 deg. At 9.80 a.m. on 

 18th its temperature rose to ]04"8 deg., and from 18th to 16th it was 

 much about tlu^ same as on 12th. 



On 17th, at 8.80 p.m., its temperature rose to 105 deg., and it was 

 very sick. Respirations, 28 ; pulse, 180 ; auscultation revealed moist 

 sounds in both lungs. The ears and belly had a dirty reddish colour. 

 C)n the back the skin was very scaly. The breathing seemed to be 

 getting easier. From 18th to 22nd the temperature kept above the 

 line of 104 deg., and it seemed to be improving. On 23rd, at 5.40 

 p.m., the temperature sank to 104 deg., and the reddish colour had 

 almost disappeai'ed. On the 24th its temperature sank to 10 1 deg., 

 and from that time onward it rapidly improved in health and 

 condition. 



The virus derived from pigs that spontaneously contract swine 

 plague is, as experimentally shown, fatal to guinea-pigs and pigeons. 



A broth culture of the bacillus did not prove fatal to an experi- 

 mental pig. 



The virus derived from a pig experimentally inoculated, and from 

 nutrient cultures, does not appear to be fatal to pigeons and guinea- 

 pigs. 



Preventive and Remedial Measures.

 When disease breaks out in a herd, where all members of it are 

 allowed to intermingle freely, mortality may be very great, particularly 

 if the surroundings are insanitary. If proper precautions are not 

 forthwith taken to combat the outbreak, 60 per cent, of the herd may 

 die. Of the remainder of the herd a few may be observed to be
