soaps, the dressing of hides, etc., while the scrap is converted 

 into fertilizers of various kinds. 



It is now stated that a new use has been found for this 

 scrap, namely, that of employing it as a source whence a large 

 amount of ammonia and other nitrogenous products may be 

 obtained. Tliis is accomplished by a certain process of treat- 

 ment with lime. It is proposed to prepare from this sub- 

 stance a sulphate of ammonia, by treating it with sulphuric 

 acid of the refineries of petroleum. Doubtless other chem- 

 ical products will also be attempted. 



The menhaden is also put up in oil in numerous establish- 

 ments in New Jersey, and sold as the American saidine^ 

 ocean trout, etc., and sometimes is also put up in spices and 

 pickled. 



Mr. Goodale, of Maine, has recently suggested another ap- 

 plication of this fish, in the preparation of a meat juice, which 

 he claims to be extremely palatable and nourishing, quite 

 equal in this respect to any of the articles of a similar kind 

 known in the trade, while at the same time the value of the 

 fish for oil and guano is undiminished. Letter of Dr. Squihbs. 



.UTILIZING THE OFFAL OF CODFISH ON THE GULF OF ST. 



LAWRENCE. 



M. Levy has lately started an establishment at the French 

 island of St. Pierre, in the Gulf of St. Lawrence, for the pur- 

 pose of utilizing the gurry and offal of the codfish, etc., taken 

 on the banks of Newfoundland. All the heads, entrails, etc., 

 are gathered in, and after the extraction of the oil, the bones 

 are converted into gelatine and superphosphates. There are 

 two factories of a similar character in Norway, one at the 

 Loffoden Islands and the other at Christiania. 8 -S, August
