available for this investigation. Tupaja, on the contrary, is 
much more common, and I might safely feel hopeful to collect 
a rich harvest of Tupaja javanica. 
Besides the additional genera of the order of the Insectivora, 
the investigation had in the second place to be directed towards 
another order which is said to occupy an intermediate place 
somewhere between the Insectivora and the highest order, that 
of the Primates, to which man and monkeys belong. This 
intermediate order is that of the Lemuride or Prosimie. In 
Europe it is no longer represented by living genera, although 
in earlier geological periods it did occur in this part of the 
world. A small number of genera compose this order, by far 
the majority of them being found in Madagascar. 
Two representatives of the Prosimiz occur in the Indian 
Archipelago, viz. Nycticebus and Tarsius. A peculiar genus 
of mammals, the so-called flying maki or Galeopithecus—dif- 
ferent in organisation as well as in mode of life—was at one 
time regarded by zoologists as being more closely allied to the 
Lemurs, at another time to the Insectivora or to the Cheiro- 
ptera, or even as an order by itself (Dermoptera). This genus 
also occurring in the Indian Archipelago, it had similarly to 
be included in the sphere of the projected investigation. 
Finally, I was interested in the only representative of the 
order of the Edentata that has as yet been brought to light 
in the Indian Archipelago, viz. Manis javanica, and desirous 
to obtain a complete series of the different stages of placenta- 
tion of this animal; the Edentates presenting considerable 
differences among themselves with respect to their placenta- 
tion. 
Coloured drawings of the above-named mammals were distri- 
buted, a few months before my arrival in India, by the Royal 
Physical Society amongst a number of persons with whom 
readiness to co-operate appeared probable. 
To this was added a circular, answers to which successively 
arrived. My friend Dr. P. C. Sluiter, librarian to the Society, 
to whose energetic assistance I am deeply indebted, entered 
into a preliminary correspondence with the writers, and placed
