work was erected within a few yards of his residence and manu- 
factory. Since that time, especially at night, sulphuretted hydro- 
gen has been evolved in large quantities from the sulphate of 
ammonia works, and the family above referred to have suffered, 
more or less continuously, from nausea, fainting, diarrhoea, and 
the other well-known effects of sulphuretted hydrogen ; all fowls 
die on his premises ; one large Newfoundland dog, after exhi- 
biting the symptoms of poisoning by this gas, died ; and his 
horses have been more or less affected. 
" In addition to the foregoing, I have examined several well- 
waters recently polluted with sewage and drainage ; and the 
general and scientific evidence obtained proved that the sickness 
and mortality among farm-stock observed in connection with 
these cases have been occasioned by the drinking of the waters 
so contaminated. 
" Among the cases of cattle-foods sent to me for analysis, I 
may refer to three, which were samples of rape-cake containing 
large quantities of charlock (wild mustard). The eating of these 
cakes by beasts, in three different counties, was followed by 
many deaths." 
XI. — Annual Report of the Consulting Chemist for 1875. 
By Dr. AUGUSTUS VOELCKEE, F.R.S. 
The appended tabulated summary shows that the number of 
samples of feeding-stuffs, manures, soils, waters, &c., sent to 
me for analysis in 1875, by members of the Royal Agricultural 
Society, exceeded the number sent in 1874 by 59. As many 
as 704 analyses and accompanying Reports were sent by me to 
individual members of the Society during the period between 
December 1874 and December 1875. With the exception of the 
year 1871, in which an unusually large number of oilcakes were 
sent for examination, this is the largest number of analyses which 
have been made by me for members in a single year, as will be 
seen by the following returns for the years 1867-75 : —

The paper which I contributed to the ' Journal,' " On the Com- 
position and Properties of Drinking Water, and Water used for 
general purposes," appears to have had the effect of directing the 
attention of country residents to the important and much-
