' that one cubic metre of cotton seed is calorimetrically equivalent to 

 about 1,000 cubic metres of air. It will thus be seen that it will be 

 no easy matter to make the requisite quantity of air pass through a 

 solid mass of cotton seed in anything approaching a reasonable time.

 el Din, Cairo, or to Mr. J. Mancantelli, c/o Messrs. Allen Alderson 

 & Co., Ltd., Cairo. 



(b) MACHINES IN WHICH THE SEED is HEATED BY RADIATION 

 FROM STEAM PIPES. 



(9) Domains' Machine. A purely experimental machine, already 

 referred to above, was erected in 1914 by the engineers of the State 

 Domains Administration. In this machine the seed was carried 

 on an endless band through a long wooden box containing a number 

 of steam-tubes by the radiation from which the seed was heated. 

 A full description of the machine and an account of experiments 

 carried out with it is given in the " Agricultural Journal of Egypt," 

 1914, Volume IV, Part II, page 115 (Storey, -''Notes on Large Scale 

 Experiment against the Pink Boll Worm in Cotton Seed"). 



For further particulars apply to the State Domains Administration 

 or the Ministry of Agriculture. 



(10) Matsowhis' (Plantas) Machine. A machine designed by 

 Mr. Panayoti Matsouchis, engineer to Messrs. J. Planta & Co., is 

 being erected at that firm's ginnery at Mansura. It consists of a 

 series of long axles bearing radiating blades, in section like a paddle- 

 wheel, arranged one above the other, alternate axles revolving in 

 opposite directions. The seed falls on the rising blades of the upper- 

 most axle, and is carried over by them as they revolve till they drop 

 it on to the rising blades of the next axle, on which they are carried 

 over in the opposite direction till they fall on to the rising blades of 

 the third axle, and so on to the bottom. During the course of this 

 journey the seed is heated by radiation from a number of steam - 

 tubes arranged in a plane parallel to that occupied by the falling 

 seed. 



At the time of writing the machine has not yet been completed, 

 *so it is impossible to give any definite opinion as to its merits. The
