drop, to separate the excess of lead as sulphate, filter and evaporate 
the fluid to small bulk at a low temperature, mix with an equal volume 
of alcohol, filter, and treat the filtrate with 15 to 20 grammes of ammo- 
nia sp. gr .960, mixed with an equal volume of alcohol. The alcoholic 
solution of ammonia is divided into two portions, which are added half 
an hour apart, after which the fluid is allowed to stand twenty-four 
hours. The morphine, which separates in distinet crystals, is collected 
on a weighted filter, washed with dilute alcohol and freed from a small 
quantity of narcotine which may be present by washing with ether. 
The remaining crystals of morphine are carefully dried and weighed. 
FLESH-MEAL.—In our monthly report for July, under the head 
‘Animal farina,” we published a description of the process of manufac- 
ture of extract of beef at Fray-Bentos, Uraguay, as well as of the 
refuse consequent upon it, together with experiments upon the use of the 
latter as feed for cattle. In an article published in a late number of “ Die 
Landwirthschaftlichen Versuchs-stationen,” (Bd. XVI, No.2 u3,) Dr Pott 
ealls this residue jflesh-meal, which seems more appropriate than that 
given in the previous article. He also furnishes results of complete 
analyses of the product, which are as follows:
