(i) The « count » number was originally used to indicate the number of hanks of 560 yds- 

 per lb. of worsted yam. For example : 



lb. of 40's worsted yarn contained 40 X 56o = 22400 yds. of worsted 

 » 6o's » » » 60 X 560 = 33600 » 11 



But in actual practice the count number represents the fineness ot the fibres rather than 

 the yield ot hanks per lb. In fact the j'arn ma3^ be classed as 6o's for the thickness of its jarn 

 even if it only j'iel ded 50 hanks per lb. on account of the lack of length and uniformity in the 

 fibres. 



1223 - New and Quick Method of Determining the Age of Eggs. — Grossfeld, in Moi- 



kerei-Zeitun^^, Year 30, No° 33, pp. 515-517. llildesheim, August 18, 1916. 



A new method has been devised for estimating the age of eggs. It is 

 based on the fact that a new laid egg is heavier than water and that it 

 gradually loses weight as its age advances. The weight of an average sized 

 fresh egg in water is 4.3 gms. and decreases at the rate of 0.6 gm. per week, 

 so that after about seven weeks the egg is of exactly the same density as 

 water and then its weight gradually passes into minus values, as the egg 

 reaches advanced stages of preservation. 



By means of a simple areometer, the weight of the egg in water can 

 be determined ver^^ quickly. The instrument is made by hugershofp, 

 GUERBER AND CO., Leipzig and consists of a graduated tube with a metal 

 basket at its base. Having^ placed the egg in the basket, the whole 

 instrument is immersed in the coldest water available and the weight of 

 the egg in water as well as its age in weeks can be read off directly from 

 the graduations. The whole operation only takes a few seconds so that 

 a large number of eggs can be tested in a short time. 



Though the instrument is calibrated for an egg weighing 54.3 gms. 

 and occupying a volume of 50 cc. , i. e. for an average sized egg, the read- 

 ings are sufficiently correct for practical purposes with all but very small
