In the present paper we publish the teratological deviations

 send him. We want to express our sincere thanks to the senders : 

 The Resident of Ternate, Mr. C. Brandts Buys, Dr. Elbert, 

 Mr. S. P. Ham, Mr. Huysmans (Buitenzorg), Mr. J. Hulshoff 

 Pol (Buitenzorg), Mr. H. ten Oever, Mr. Phaam, Mr. Salverda, 

 Mr. Schreuders (Bandong) and Dr. Th. Valeton (Buitenzorg)

Our former papers on the same subject are to be found in 

 the present publication of 1895, 1904, 1905 and 1909.
