SPOLIA NEMORIS. 81 
and how the preservation was to be done. Now that three 
years have passed by, I may safely say that the results have far 
surpassed my expectations. 
Among the hundreds of persons with whom these roamings 
through the woods and mountains of Java, Sumatra, Banka, 
Billiton and Borneo have brought me into close connection, 
and who have been interested in the object of my investigations 
as explained to them by me, it is only natural that the great 
majority has been unable by various circumstances to contri- 
bute in any way towards the increase of my embryological 
collection. 
They, however, who have thus contributed can hardly have 
imagined how their apparently small collections—but which are 
being forwarded from numerous parts—can together constitute 
a very considerable array of important material for research. 
Such has undoubtedly been realised on this occasion, consider- 
ing that at this present moment I already dispose of— 
469 uteri of Tupaja, 
137 »  Nycticebus, 
72 »  Galeopithecus, 
198 ee Lars, 
150 >» Manis, 
making the respectable total of 1026. This collection is yet 
increasing continually by new arrivals. 
The majority of these uteri are pregnant in one stage or the 
other ; many have been preserved very shortly after parturition ; 
only a very few are virginal. 
The pregnant uteri contain the most divergent stages, from 
the earliest phases of segmentation to the nearly ripe or newly 
born foetus. Several newly born young have also come into 
my possession, as also a few in the very act of birth, the nearly 
born foetus being still connected by its umbilical cord with the 
as yet adherent placenta. 
The numerous microscopical preparations which have already 
1 While correcting this proof, new arrivals have again increased this total 
to 1072.
