538 Kidd V. Royal Agi'icuUural Society oj England. 
Re-examined hy Mr. Field. 
Q. You took out the heart, lungs, liver, and kidneys, and also all the four 
stomachs, and placed them in a large box ; everything just as it was ; but do 
not know what became of them yourself? Would it make any difference in 
your opinion, or in the result, supposing the intestines had not 'been examined, 
but only the heart, lungs, viscera, and kidneys ; would that make any differ- 
ence in your opinion? Do you think an experiment could be made, or a 
result obtained, from an examination without the intestines? — A. You could 
know whether the animal was healthj' at the time or not. 
Q. You were asked with reference to the 7 lbs. of cake that were given at 
Booth Ferry, G lbs. to the cows there, 4 lbs. at the Airmyn Pastures Farm, 
and at Sancton Farm only 3 lbs., and you gave your answer in reference 
to that. Now, I want to ask you this — supposing at Sancton the 3 lbs. of 
cake were given tof;ether with chopped hay or oats, would that, in your 
judgment, tend to diminish the effect of the cake upon the stomachs? — A. Of 
course it would. 
Q. Is it not the fact that the animal's food remains for a long time in the 
rumen? — A. It is. 
Q. It is first, of course, taken in by the mouth and deposited in the rumen? 
— A. Yes. 
Q. From the rumen, under natural circumstances, it goes back to be 
chewed ? — A. Yes. 
Q. But remains for a long time in the rumen. Whatever food had been 
given an hour before would be still remaining in the rumen when the cake 
would be given ? — A. It would. 
Q So that there would be a large mass of food in the rumen, irrespective of 
the cake, with which the cake would mix as it were ? — A. Yes. 
Q. You w^ere asked whether you would expect to find in the contents of the 
stomach traces of poison if poisonous material had been administered.? Do I 
understand that in hoven the effect is to press upon the diaphragm ? I think 
it was so read from that book? — A. Yes. 
Q. Does that affect the lungs ? — A. It causes a pressure on the lungs. 
Q. So that the animal cannot take in its proper quantity of air to decar- 
bonize the blood ? — A. No, it cannot. 
Q. So that, although there may not be poison in the stomach itself, the blood 
becomes in effect poisoned by the non-removal of the carbon ? — A. It does. 
Q. Now, you were asked whether hoven w'as generally attributable to change 
of food ; in what cases have you known hoven arise from change of food, and 
what was the change of food? — A. I have known it when they have been 
taken out from a bare jiasture and put into a good clover fog. 
Q. Have you known it in any other instances of change of food? — A. I 
have known it when a single beast has got to a potato pile — or anything of 
that sort — that has been hungry before. 
Q. Where animals have had 7 lbs. of cake regularly from October down to 
the middle of February and are off cake for say six to ten ,days, in your 
judgment would the administration of 7 lbs. then — the ordinary dose — cause 
hoven ? — A. I do not believe it would. 
Q. And you see nothing in this course of feeding which in your judgment 
would cause hoven? — A. I do not. 
Professor JAMES BEART SIMONDS sworn : examined hj Mr. Field. 
Mr. Field : Before I proceed with the examination of Professor Simonds, I 
ought to say that I have the station-master and the clerk here, who took this 
box to the station, and if I am put to it, of course I must call them. -
