visible result, but on the sixth the Boletus was abundant every- 

 where. The species had never been found before within a mile of 

 the spot." The patience of the French was surely well exemplified 

 in this instance. Here we expect two crops in a year in our 

 cultivated lands, while in France results are waited for for five 

 years on waste land. With our agricultural energy we shall soon 

 have no wastes or Boletuses left. A curious phenomenon is to be 

 seen in certain species of Boletus, the flesh, when broken, changing 

 from white or yellow to blue. It is stated that Professor Robinson 

 has ascertained that this is not due to chemical action but to some 

 change in the molecular arrangement. Roques says of B. Luridus, 

 that a cat died in 24 hours after eating an ounce of it. A young 

 surgeon who had eaten one of these Boletuses, experienced intense 

 heat in the throat and stomach, attended with spasms and great 

 weakness ; the pulse rapid with a burning skin, and after a medical 

 treatment of some hours he recovered. He records another instance 

 which proved fatal to a Chevalier P. The species hitherto met 

 with in our district are —
