The next volume is to be wholly occupied by Prof. Engler's 

 monograph of AroidecB. Would it not conduce to lu'ompt publication

In a paper in the ' Proceedings of the Royal Society of 

 Victoria' Dr. J. Jamieson calls attention to a point in the 

 respiration of plants not hitherto examined, namely, the trans- 

 formations undergone by the oxygen. From various experiments 

 and considerations he is led to believe (1) that the oxygen inhaled 

 by i)lants, as well as by animals, enters first into some form of 

 loose combination, as in the blood, whereby it is ozonized or 

 rendered active, and is capable of being slowly given off to 

 combine definitely with oxydizable substances; and (2) that 

 plants contain a substance, other than chlorophyll, having some 

 important points of analogy with the haemoglobin of animals and 

 acting like it as an ozone-transferer.
