Topographical anatomy of the horse, W. Ellenberger and H. Baum (Topo- 

 graphische-Anatomie des Pferdes. Berlin: Paul l'arey,1897, 3 col*., pp. o:,l; rev. in 

 Nature, 56 {1897), No. 1460, p. 586). 



TECHNOLOGY. 



Paints and painting materials and miscellaneous analyses, H. 

 H. Harrington and P. S. Tilson (Texas Sta. Bid. 44, pp. 9H1-973).— 

 Tesus of the drying properties of crude and refined cotton-seed oil and 

 analyses of thirteen samples of commercial paints are reported. The 

 conclusion is drawn that cotton-seed oil may be used for rough outside 

 painting in summer weather, especially if mixed with a dryer, but in 

 no case will it give the luster or hardness which may be obtained with 

 linseed oil. "Its durability may, however, be even better." It is 

 recommended to buy the oil and pigments separately and mix them to 

 suit, rather than to buy the ready mixed paints. 



Analyses of 36 samples of mineral waters, 2 of damaged cotton-seed 

 meal, 6 of coal, 4 of copper ore, 2 of iron ore, 2 of clay, 1 of fertilizer, 

 1 of calcareous shells, 2 of asphalt, 2 of ashes, and 2 of satol (whole 

 plant and inner portion), and the results of an examination of 2 distil- 

 lation by-products from lignite tar are also reported. 



Notes on cold storage, F. W. Kane (Proc. Soc. From. Agr. Sci., 

 1897, pp. 53-59). — This is a general discussion of the use of cold stor- 

 age for the preservation of agricultural products of various kinds, 

 including an account of a cold-storage cellar constructed at the Kew 

 Hampshire Station in which apples and potatoes were successfully 

 stored. The principle upon which this storage cellar was constructed 

 is thus explained : 



"It might be termed climate cold storage, and consists of studying and husband- 

 ing the lowest temperatures of one's climate to do one's bidding. There are few 

 days at a stretch from .September until late in spring in New England, for instance, 

 but that the temperature falls at some time sufficiently to utilize it for cold storage. 

 Being prepared to retain this temperature in cellars or buildings constructed for the 

 purpose until a similar or lower temperature is again realized is the key to its suc- 

 cess. From experience it is believed this simple method can with comparatively 

 little care and expense be made more useful at present (in this our transitory stage) 

 than all others. It is not offered to take the place of other systems already men- 

 tioned, but to meet an apparent need in our rural districts." 



Wool scouring, E. F. Ladd (North Dakota Sta. Bui. 82, p. 271).— The losses in 

 weight from scouring three samples of wool were 60.01 per cent, 62.64 per cent, and 

 61.77 per cent. It is stated that these were "fair samples from the sheep as found 

 on the prairies in the sheep belt of the western part of the State. . . . Data that 

 have come under the observation of the writer have shown a loss of from 55 to 70 

 per cent from scouring samples of North Dakota wool.'' 



On the natural occurrence of large amounts of potassium chlorid and sodium 

 chlorid in the juice of grapes and in the wines of the saline regions of Oram 

 E. Bonjkan (Compt. Bend. Acad. Sci. Paris, 126 (1898), No. 18, pp. 1275-1277).— The 

 French law requires that wine shall not contain more than 0.607 gm. of chlorin per 

 liter. The author found more than this in grapes of the province of Oran and in the 

 wine made from these grapes.
