Dr. Vriese's note on the temperature of the male inflorescence of 

 Cycadeous plants is very interesting. " Very recently a high degree 

 of temperature has been observed in a plant belonging to a family in

 chief gardener at Burtenzorg, in Java, in 1845, has informed me that 

 he has observed an elevated temperature, and at the same time a very 

 strong smell, in the male cone of Cycas circinalis. I received from 

 him, in October, 1849, and November, 1850, seven series of observa- 

 tions, made in the aforesaid garden, upon male flowers of this plant. 

 What is most remarkable in these observations is connected with the 

 following facts. The elevation of temperature dways takes place be- 

 tween 6 — 10 in the evening. Messrs. Bory, in the Isle of France, and 

 Hasscarl, at Java, have observed the maximum at 6 in the morning. 

 De Saussure observed it in the Arum Italicum between 4 — 7 in the 

 evening; and the Colocasia odora in the gardens of Paris, Amster-
