Interim Report on Veterinarij Investigations. 205 
On the result of the experiment beings reported to the Marquis 
of Exeter, his Lordship communicated the circumstance to tlie 
Council of the Society, when some members appeared to think 
that the death of the animal was rather due to the quantity of 
the cake partaken of, than to anything deleterious which it mio;ht 
have contained. It was therefore determined to have recourse 
to some other experiments of a like kind with Hardon's cake, 
and to contrast these with experiments in feeding other young 
animals with large quantities of pure linseed cake. For this 
purpose two heifers — each about lO months old — were selected, 
and three pigs, between three and four months old. A fresh 
supply of Hardon's cake was obtained for the experiments from 
the Marquis of Exeter. 
11. — Second Experiment with Hardon's Cake. 
July nth, 1871. Heifer A. — 2 lbs. of cake, in addition to 
other food of the ordinary description, were given to this animal. 
It was readily partaken of. On the 18th, 19th, 20th, and 21st, 
the same quantity was allowed on each day. On the 22nd. 
3 lbs. were given, and repeated for three consecutive days. 
During the four following days, 4 lbs. were allowed ; and on 
the 29th and 30th, 5 lbs. On the 3lst, 6 lbs. were given, and 
continued daily to August 3rd. On August 4th the quantity 
was increased to 7 lbs., and subsequently repeated day by day 
in this proportion throughout the month of August, and down to 
September 7th, when the experiment ceased. 
During the entire time the animal did not appear to have its 
health impaired, beyond an octasiojal slight attack of indi- 
gestion. Its general condition, however, was but little improved ; 
the inference being that the cake possessed only moderate feeding 
qualities. 
III. — Linseed Cake. 
This cake was of best quality. 
Juli/ nth. Heifer B. — 2 lbs. of cake were added to the food 
of this animal, which was of the same kind as that supplied to 
Heifer A. As in the other case, no increase was made in the 
quantity of the cake until July 22nd, when 3 lbs. were given 
and continued for the three following days. On the 26th the 
quantity was raised to 4 lbs., at which rate it was supplied for 
the four following days, when it was increased to 5 lbs. Two 
days subsequently it was raised to 6 lbs., and on August 4th to 
7 lbs. Throughout the remaining part of the month, and down 
to September 7th, when this experiment also ceased, the animal 
was supplied with 7 lbs. daily. During the entire period tiie 
animal tontinued in perfect health. No loathing of food was at
