if care be not taken to preserve them in a dry place, whereby a por- 

 tion of the excess of moisture may be removed. The author has 

 found that the disease remains stationary when they are dried ; at 

 least at the end of several weeks it had not attacked the neighbour- 

 ing parts. These diseased potatoes might be used to obtain potatoe- 

 starch, as also for distillation, without there being any necessity for 

 throwing away the diseased portions or even those which have be- 

 come putrid ; in the preparation of starch, however, the washing 

 must be continued longer than usual. They may also be used with- 

 out injury, after having been boiled, to feed cattle upon, but the 

 water in which they are boiled should be thrown away. They are 

 perfectly useless for planting, for the disease is found generally to 

 extend from those points at which the young buds are situated ; the 

 germ is also frequently destroyed. — Bot. Zeitung, Oct. 10, 1845.
