the late Prof. Fjord, of Den- 

 mark, mentioned in the chap- 

 ter on heating milk for sep' 

 aration (See Fig. 28). These 

 have been greatly improved 

 by the government experts of 

 that country. In Fig. 77 I il- 

 lustrate one of these modern 

 Danish heaters. It is hung 

 on pivots u on a neat iron 

 frame screwed on to the floor 

 and ceiling. The steam is let 

 into the well insulated jacket 

 n from the pipe m, which is 

 easily desconnected by a un- 

 ion. The condensed water 

 leaves through the waterlock, 

 having an air cock. r. The 

 tinned copper cylinder v is 

 provided with drip-rings or 

 flanges o o, and the dasher 

 c with foam-killing plates. 

 The milk enters at a and 

 leaves through the lower 

 (Fig. 77) opening e and what little foam 



which is not destroyed in the room d k leaves by /. 



On this side of the water, the one made by A. H. Reid (Fig. 



78) and also the one made by 

 Jensen Mfg. Co. represent this 

 type. Of other, heaters I refer to
