526 Kidd V. Royal Agricultural Society of England. 
Q. And also consulting chemist to the Eoyal Agricultural Society? — I was 
for eight or nine years. 
Q. Did you assist Professor Voelcker in making an analysis ou the 16th of 
July ?—A. I made with him an examination of two samples of cake on the 
16th of July. 
Q What was the examination you made ? — A. We made a few simple testa 
as to the character of the cakes, and also some microscopical, or rather optical 
examinations — examinations under a strong lens. 
Q. Did you make any notes yourself? — A. I did not make any notes. 
Q. Have you heard Dr. Voelcker's account of it to-day in the witness-hos ? 
— A. I have. 
Q. Speaking from memory is that correct ? — I believe so. There are some 
points which Dr. Voelcker has spoken to which I should rather not say any- 
thing about, simply because my botanical knowledge is not very great, and I 
do not profess to give any opinion upon that. There were some things 
which I v.'as competent to detect in the analysis, others were pointed out to 
me by Dr. Voulcker, but which I do not profess to know. Simply, I could see 
that there were a good many seeds which should not be present in a genuine 
linseed-cake. 
Q. Tell us what you observed yourself.? — A. I saw particles of bran, of 
husks, and of what I considered to be oats and barley, and a great variety 
of seeds which I know to be seeds of weeds, but which I could not 
particularly specify. 
Q. Do you know anything of the properties of the seeds of weeds you saw? 
— A. I do not. 
Q. Is there anything else ; can you tell me anything that you noticed 
yourself, and which you knew ? — jSTo. 
Q. Either the name or what it was ? — A. No. 
Q. Nothing else ? — A. No, nothing else. 
Q. Will you tell me the result of what you salw ? — A. I think you must 
take generally from me that, so far as my knowledge goes, and having 
formerly examined very many sampler, of pure linseed-cake, I considered 
this to be an inferior cake. That is the general result of my examination 
— cake made from dirty seed or from mixed materials other than linseed. 
Perhaps you will allow me to say that at the time when I was the chemist of 
the Agricultural Society it was not usual to find any great number of adul- 
terated cakes, and therefore my experience deals more with good cakes. 
Cross-examined ly Mr, Seymour. 
Q. Just one question or two. I suppose in the hay that the cattle eat 
there is a certain proportion of what you call weeds ? — A. No doubt. 
Q. What is a weed ? Do you agree with the poet that it is a flower out of 
place. I think that is the definition we have had of it. Just take that bottle 
and look at that sample of seed (hands a bottle marked C to the witness)? — 
A. Yes. 
Q. Can you detect any of those foreign seeds in that ? — A. That is a toler- 
ably pure specimen of seed, I should say. 
Q. Do you find there several of those vegetables that we have heard 
mentioned ? — A. I can see seeds other than linseed, but not in very great 
numbers. 
Mr. EICHARD V. TUSON sworn : examined ly Mr. Field. 
Q. What arc you ? — A. I am Professor of Chemistry at the Pioyal Veteri- 
nary College in London.
