124 plants are enumerated in the above list. Of these, 
15 are repetitions of species previously recorded; 2 are 
varieties of other species ; and 2, Anthemis arvensis and 
Verbascum Lychnitis, cannot be claimed as Worcester records. 
After making these deductions we have 105 new records to 
the credit of Dr. Stokes.

A Junior Course of Practical Zoology. By A. Milnes Marshall, M.D., 
D.Sc., M.A., F.B.S., assisted by C. Herbert Hurst. London: 
Smith, Elder, and Co. 
The want of such a work as this has long been felt both by teachers 
and students, as the well-known “Elementary Biology” of Huxley 
and Martin does not treat of several animals, the structure of which 
it is important that a beginner in Zoology should know thoroughly 
well. Its appearance, therefore, will be heartily welcomed by 
Zoologists. 
The book opens with some very valuable instructions on methods 
of study, which ought to be well taken to heart by every beginner; 
those on dissection, in particular, being extremely good and to the point. 
The remarks in this and the last chapters on the preparation and use 
of reagents are also very useful. 
The body of the book is composed of directions for the examina¬ 
tion and dissection of the following animals: Amoeba, Paramoecium, 
Opalina, Vorticella, the freshwater Hydra, Liverfluke, Leech, Earth¬ 
worm, fresh-water Mussel, Snail, Crayfish, Cockroach, Lancelet, 
Dogfish, Babbit, and Fowl. This list, it will be seen, contains the 
types which it is most important a beginner should understand, with 
the exception of that of the Frog; Professor Marshall has, however, 
previously described this animal in a former work which it would be 
advantageous to have incorporated with the present volume. The 
treatment is admirable : full directions are first given as to the dissec¬ 
tion necessary to expose an organ, and then follows a description of 
the latter and of its relation to neighbouring structures. In order to 
attract attention to them, the directions are printed in italics, whilst 
a system of indentation has been used to render the subdivisions of the 
descriptions more distinct. Some structures which present special 
difficulties have been treated at great but not undue length, whilst 
others, such as the muscular system, which the author regards as of 
subordinate educational value, have, owing to the short time usually 
available for laboratory work, been almost entirely omitted. 
Although the book is essentially practical, yet the “ morphological 
salt ” of which Professor Michael Foster speaks has been plentifully 
scattered throughout its pages. This is a valuable feature, and the
