what really goes on in Nature. That, however, is not his fault. It is simply 
due to what Dr Johnson called our “sheer ignorance.” 
One of the features of the hook which especially attracts us is the novelty 
of its illustrations: many of them are new, many of them are taken from 
recently published scientific papers, and the well worn “hack” figure is 
mercifully spared us. 
We have in fact nothing but praise for the book, with the solitary exception 
that we should have liked to have had one of the figures taken from our own 
work attributed to its source. 
Prowazek, S. von (1909). Taschenbuch der mikroskopischen Technik der Protisten- 
untersuchung. 2nd ed. Leipzig: Yerlag von Johann Ambrosius Barth. 
87 pp.17 x 11 cm. Price 2.50 Marks. Cloth. 
The second edition of this useful little pocket-book will be welcomed by 
protozoologists since it contains many additions to the previous edition. To 
our knowledge there is no other book of the kind. We can safely recommend 
it to workers in the laboratory. 
Thimm, C. A. (1909). Bibliography of Trypanosomiasis. Issued under the direction 
of the Honorary Managing Committee of the Sleeping Sickness Bureau, London. 
228 pp. 25 x 16 cm. London: Sleeping Sickness Bureau, Royal Society, 
Burlington House, W. Price (Paper cover) 4s. net. 
This bibliography, compiled by the Librarian of the Bureau, will prove quite 
invaluable to those interested in trypanosomiasis since it contains nearly 2000 
titles of publications arranged both according to authors and to the journals in 
which they appeared. All papers which appeared before April 1909 are 
included and references to Glossina literature are given. The costs of 
publications have been heavy and the price of the bibliography is not calculated 
to do more than cover a part of the costs of production.
