| X.4607 24 Basekir Road Custom House London E.16 Sept. 12. 25 Dear Sir Many thanks for your favour just to hand. The sample I have made is only a small affair as it is sent up for you to test it. It is only about 5" x 5" x 1/2". & I will get a little box to pack it off on monday. You can test it either by blowing through it, or by using a small bellows. The air will be cold if blown through from one side of device, & hardly felt at all if blown from the back. The faster a car or aeroplane travels the colder will be the air passing in. Hoping to have a favourable report. I am Dear Sir yours respectfully Edward Adowre | ||
