with the help of our method we could hope to obtain certainty in 
this matter, we proceeded at once to testing our hypothesis. 
For this purpose the first thing we needed was a Linnean de- 
scription of the wood of Aptiana in order to compare it with the 
several summarizing descriptions of the wood of whole families, 
already published in our “Mikrographie des Holzes”. Having done this 
we found, that our first impression had been correct and that Aptana 
was no doubt a plant belonging to the family of the Ternstroe- 
miaceae, very nearly allied to the genus Lurya, if not belonging 
to it indeed. 
In order to give the reader the means of judging for himself, we 
will now go somewhat more in detail, first giving the Linnean 
description of Aptiana, mentioned above, then a translation of our 
description of a species of Eurya, given in the “Mikrographie des 
Holzes”, and ending with a discussion of the results obtained. 
The Linnean deseription of the wood of Aptiana now following 
was of course abstracted from the paper of Mrs. Stopes. The data 
thus gathered were arranged in the Linnean fashion, according, fo a 
form for the description of secondary xylem, which we always 
use as a basis of our deseription *). As far as possible Mrs. Sroprs’ 
own words were used and the pages where they are to be found 
were mentioned. But in some cases, where our interpretation dis- 
agreed with that of the writer or where characters were described 
only to be seen in the drawings or photos, this was of course im- 
possible. These passages were printed in italics and if necessary a 
footnote explains why it was desirable to alter the writer’s statement.

2) On p. 85 is added: “but not clearly marked by any noticeable change in 
the character of the wood or size of the vessels.’ By studying Pl. 6 Photo 4 and 
Pl. 7 Photo 6 we have come to an opposite opinion, to that mentioned in the text.
