SOCIETY MEETINGS. 
and after allowing the micrococci to develop in it until August 24tli, I inoculated 
two guinea-pigs from the culture. For this purpose I used a sterilized hypoder¬ 
mic syringe, and injected the culture under the skin of the abdomen. To distin¬ 
guish these guinea-pigs, I will call them No. 1 and No. 2. 
August 27th, three days after inoculation, No. 1 was noticed to have some 
difficulty in breathing. Respiration was rapid and somewhat labored, and when 
held up close to the ear the respiratory murmur was so harsh and loud that it 
could be easily heard over both lungs. Otherwise he did not appear to be particu¬ 
larly sick. 
August 28th—No. 1 appeared the same as day before. 
No. 2 showed symptoms similar to No. l’s, but not so well marked. 
August 29th—Pig No. 1 is killed. The autopsy showed the viscera in an 
apparently healthy condition, excepting the lungs. The anterior lobe of the left 
lung is hepatized, and the posterior portion of the right lung very much con¬ 
gested. 
Several test tubes of agar agar are inoculated from the diseased portions 
of lung. 
Pig No. 2 is kept for further observation. 
September 2d (Friday)—Pig No. 2 seems Sicker to-day than at any time 
since he was attacked. 
September 9th—Pig No. 2 has steadily improved since Sept. 2d, and is now 
nearly well. 
Examined cover glass preparations from second generation of cultivations 
from lung of pig No. 1 (second generation being raised in order to get a pure 
culture, the first being mixed). 
The cultivations present the same appearance in agar agar as those used to 
inoculate the pigs, and also have the same appearance under the microscope. 
Sept. 15th—Guinea-pig No. 2 appears well again, and is rapidly regaining the 
flesh which he has lost. 
I had a telegram on the morning of Sept. 13th from the New Hampshire 
Cattle Commissioners, to proceed to Cornish, N. H., and investigate a supposed 
outbreak of contagious pleuro-pneumonia. 
Cornish is in Sullivan county, north of Hillsboro and Cheshire counties. I 
i mmediately repaired to the scene of action, and found a similar state of affairs 
prevailing to those witnessed on Lyndeboro Mountain earlier in the season. 
Here I find that a number of steers, chiefly two-year-olds, brought from the West 
a few weeks ago, have been turned out to pasture. 
They were brought on from Iowa, three or four weeks before my visit, pass- 
igg through the Chicago stock yards on their way. The drove originally num¬ 
bered 110, but small lots were sold, from time to time, until only 44 remained. 
The week before my visit some of these sickened, four died, and one was killed, 
so that when 1 saw them (Sept. 14th), but 39 remained. Five of these were sick, 
their symptoms resembling those of the sick cattle seen on Lyndeboro Mountain 
the last of July. Of the five, four were convalescing and one was still in the 
acute stages of the disease, having a temperature of 105^-° F. 
I had the animal which had most recently died exhumed for an autopsy. As 
he died Sunday night and was buried Monday morning, he was still (on Wednes-
