INTRODUCTION 
Mr. HOUWINK’S experiments have suffered from almost every ima- 
ginable untoward circumstance, formost among which was the war. 
Every thing became so expensive that even the most rigid economy, 
and the cutting down of the experiments to crosses of different-species 
of Gallus and of rabbit and hare, still surpassed the available means, so 
that Mr. HOUWINK finally had to decide to put a stop to the work. 
The matter was put before the Dutch Society for the Promotion of 
Scientific Breeding, which resolved to try to raise the necessary funds 
for the continuation of Mr. HoUwINK’s experiments concerning the 
origin of domestic animals, it being enabled to do so by the liberality 
of one of its members, Mr. B. WILTON of Rotterdam, who put sufficient 
means at its disposal to liberate the junior author, for the period of a 
year from all official duties, thus allowing him to devote all his time to 
efforts to raise the necessary capital. 
Unfortunately the results of the war affected Holland to such a de- 
gree, that the heavy taxation unavoidable to overcome them, forced 
even wealthy persons to the strictest economy, so that no sufficient 
funds could be raised.
