sample 1 found it to be impregnated to a considerable extent 
with lead. It was found that a patch had been made with 
lead when repairing the cask, and no doubt in this way the 
lead [came in and caused the harm complained of.

A' case involving a somewhat unaccountable loss of calves 
was investigated by me, for a member of the Society. He had 
to complain of the death of a number of his calves. The 
different foods given to them were analysed and found to be 
perfectly good. Attention was then turned to the fact that the 
walls of the stalls in which the calves were had been white- 
washed with a preparation sold as taking the place of lime- 
washing. The walls were noticed to be scaling, and the 
calves licked the loose pieces off. An examination of some 
of these pieces revealed the presence of a decided amount of 
lead, and subsequent examination of the stomachs of some of 
the calves that died also showed lead in quantity. The vendors 
of the paint maintained that they did not use lead in their 
preparation, and a sample they submitted direct certainly 
contained none, but was composed chiefly of carbonate of 
lime with zinc and some barytes. The vendors, however, 
were not themselves the makers, and, anyhow, it was made 
clear that the deliveries made to the owner of the calves did 
contain lead paint, and the calves, attracted no doubt by the 
linseed oil in the preparation, licked it off, and so took the lead 
into their systems, with the disastrous consequences related.
