is built up, in two or more parts, to form a backing for the 

 mould. The two parts are then opened, and the canvas and 

 clay taken out and thrown away, the two parts are replaced, 

 and a hollow interval of the thickness of the clay will exist, 

 into which hot liquid gelatine is poured. After twelve hours 

 the gelatine will have attained a semi-solid consistency, which 

 will allow of the mould being opened and the gelatine im- 

 pression peeled from the face of the model. 17 A^JSlay 1,

NEW STUFFING FOR CUSHIONS. 



A material which has come quite extensively into use in 

 Germany as a substitute for hair in the stuffing of saddles, 

 etc., consists of a mixture of flaxseed and tallow. The ad- 

 vantage of this substitute consists primarily in the fact that 

 the mobility of the seeds, one upon the other, prevents the 

 packing or settling in any particular place, as often happens 

 in saddles stuffed with hair, thus causing any given pressure 

 to be readily and uniformly distributed over any given sur- 

 face. The tallow serves the purpose, too, of keeping the 

 leather flexible, and of preventing the absorption of perspi- 

 ration, protects the article itself, and prevents the back of the 

 animal from becoming galled. Animals with sores or galled 

 spots on the back can be ridden with saddles stuffed with 

 this material without any great inconvenience. The tallow 

 also has the effect of preventing the rotting of the flaxseed, 

 and is to be added in sufficient quantity to give the requisite 

 softness to the entire mass. An aromatic odor can be im- 

 parted by introducing oil of turpentine, or camphor powder, 

 and the durability considerably increased thereby. One part 

 of tallow to from six to ten parts of flaxseed may be used, 

 according to the temperature. 8 (7, November 23, 1871, 375. 



GLAZING FOR FRESCOES. 



It is stated that paraffine dissolved in benzole or Canada 

 balsam affords a glazing for frescoes much superior to soluble 

 glass. 18 A, March 8, 1872, 631. 



NEW GROUND FOR STERE0CHR0MIC PICTURES. 



A new painting ground for stereochromic pictures, invented 

 by Schweiger, consists of carbonate of lime, cement, and
