viz. the Malacopterygii and Ostariophysi. Detailed criticism must be reserved 

 until the publication of Dr. Chaudhuri's complete paper, but we have already 

 sufficient to show that this, the most important constituent of the fauna of the 

 Lake, will be dealt with in a proper and scientific manner. With each succeeding 

 paper on the fish fauna of India we are more and more compelled to the conclusion 

 that the volumes by Day (1889) are hopeless as guides to the fish of India. We 

 should like the Editor of the "Fauna of British India" to arrange with the 

 Superintendent of the Indian Museum for a re-issue of the volumes on fish in 

 that series. We believe there would be a real demand for such a work amongst 

 the sportsmen and naturalists in India. 



The part of the records devoted to the zoological results of the Abor expedition 

 of 1911-12 deals with the Terrestrial Isopoda and the sixth part of the Mollusca ; 

 the former by Dr. Collinge, the latter by Lieut. -Col. Godwin-Austen. 



The remainder of the parts of the "Records" are devoted to, for the most 

 part, faunistic descriptions of various groups of Indian animals, including Odonata, 

 Lignicolous Beetle larvae, Terrestrial Isopoda, two new fish from Chilka, a new 

 Chlamys from Calcutta, and a description of a Coleopterous larva (Lasiodactylus). 



There are also papers on Aphides, Cestoda, Dragonflies, and Mollusca from 

 Cochin and Ennur. 



In Vol. XII., Pt. I., there is an interesting account of the Hydrozoon Campanula 

 ceylonensis, Browne, by Major Lloyd and Dr. Annandale. This is a brackish 

 water species found in great numbers near Calcutta. 



It is impossible to review in any detail the numerous papers printed in the 

 above publications. At a time when scientific work in Europe is being reduced 

 to a minimum it is refreshing to contemplate a part of the world where conditions 

 appear to be more tranquil.

In criticising this Laboratory Manual, it should be remembered that it is supposed 

 to be used by students who are being directed in their work by a competent 

 instructor, and therefore omissions which seem at first sight to reduce its usefulness 

 must to a very large extent be regarded as of little real demerit. Part I. deals 

 with laboratory methods which are used in the study of micro-organisms, and 

 some of the methods are those specially useful in dealing with agricultural 

 problems, and are therefore not found in the ordinary text-books. This part of 

 the book gives all that is necessary to enable any ordinary student to do 

 satisfactory work, and should be of the greatest value to those who are trying to 

 get a good working acquaintance with bacteriological methods. Part II. deals 

 with the physiology of micro-organisms, and though parts of this are good, 

 yet, on the whole, an attempt has been made to do too much, and in consequence 

 some of the exercises are scrappy and rather confusing than otherwise. Much 

 of the work here is of extreme value and it is to be hoped that in a future 

 edition this part will be elaborated and extended, e.g., the exercises in the 

 enzymes. Applied bacteriology, including the bacteriology of the air, water, 

 sewage, and soil, is treated in Part III., and in addition some exercises are given 

 in dairy and plant microbiology, and a few on animal diseases and immunity. 

 These latter are, we think, the weakest in the whole work, and some parts strongly
