Dr. Voelcker's subsequent analysis and report upon the 
sample sent to him were : —

" An impure cake, with considerable admixture of seeds other than 
linseed, and too much sand. " J. Auausxus Voelckek." 
Mr. Norris, having previously purchased a lot of Russian 
cake from the same vendors, wrote to them to ask whether the 
two last lots were of the same parcel, and received the following 
reply : ^ggg^ 
"Sir, — In I'eply to yours, the two last lots of cake we sold you were 
UlanofF's make ; the first 4 tons were x 200 tons per ' Leo,' which you 
bought on December 10 ; and the second 4 tons x ' Mabel ' {ex 100 tons), 
which you bought on the 18th ultimo. Not being the manufacturers, we do 
not guarantee any cake, and we are not responsible after goods have left our 
possession, as you will see by our contract. — Yours truly, 
" ROBEET & JnO. HeWETSON." 
This case shows clearly that it is unsafe to rely upon the 
printed analyses circulated with regard to cake of a certain 
brand, and that purchasers should be careful to insist upon the 
vendors' guaranteeing the particular delivery. 
3. Mr. Robert Marshall, of Ley Fields, Kneesall, Newark, 
sent on March 25, 1889, a sample of raw bone meal for 
analysis. Five tons of this had been purchased, at 5Z. 5s. per 
ton delivered, net cash, from Messrs. J. & T. Walker, of 
Nottingham, who were the manufacturers. The following is Dr. 
Voelcker's analytical report -
