510 SUPPOSED DEATH OF COWS FROM SPRAY OF BULLETS. 
I now beg to furnish you with the following report upon the 
results obtained. 
The Stomach .—Fragments of bullet-spray were found ad¬ 
hering to the coats of the stomach. These were picked off, 
and about eight ounces of the stomach, thus freed from spray, 
were washed in distilled water, for the purpose of endeavour¬ 
ing to remove any mechanically adhering lead which might 
have escaped detection by the eye, and then analysed. Most 
decided evidences of the presence of lead were obtained. 
The Intestines .—About eight ounces of the intestines were 
examined in precisely the same manner as the stomach, and 
lead was discovered in them. 
The Liver and Kidney .—On testing portions of these organs, 
after rinsing them in distilled water, for lead, that metal was 
detected; but it evidently existed in the liver and kidney in 
much smaller quantity than in the stomach or intestines. 
The Bullet-Spray .—In addition to the above-mentioned 
analysis, the following experiments were made on the bullet- 
spray which you forwarded to me, and which, I understand, 
was found among the herbage in the pasture adjoining the 
Rugby rifle-butts. Some of the flattened, irregularly shaped 
fragments of lead constituting the spray, had a semi-metallic 
lustre, indicating that part, at least, of the metal had under¬ 
gone but little chemical change. Most of the fragments of 
spray, however, had suffered considerable alteration, as was 
shown by their being coated with a drab-white incrustation. 
This drab-white incrustation was analysed, and found to 
contain carbonate of lead, and I believe, if a sufficient quan¬ 
tity of the incrusting material could have been obtained, so 
as to have enabled me to have conducted a more complete 
and quantitative analysis of it, I should have ascertained that 
it consisted of a mixture of carbonate of lead with oxide of 
lead. I may here remark, that the lead found in the stomach 
of the cow possessed similar characters to the spray picked 
up in the pasture. 
Some special experiments were made with reference to the 
action of solvents, possessing similar qualities to those con¬ 
tained in the alimentary canal, upon the incrusted fragments 
of bullet-spray, and I find that chloride of sodium (common 
salt), alkaline solutions (water containing carbonate of potash 
or carbonate of soda), and exceedingly dilute hydrochloric 
and acetic acids, will act upon and render soluble a portion 
of the lead. 
The conclusions, therefore, which I think we are justified 
in drawing from the foregoing experiments and observations 
are—
