N many ways the completion of the present volume of 

 the International Journal of Microscopy and Natural 

 Science compels us to say a few words respecting it. 



On glancing through the volume, we cannot but feel 

 a just pride in the variety and general excellence of the many 

 papers and articles it contains. Amongst the important contribu- 

 tions, the continuation of the translation of Dr. F. Vicentini's 

 memoir on the " Bacteria of the Sputa and Cryptogamic Flora of 

 the Mouth," which is completed in the present part (October), 

 deserves especial mention. Indeed, so well has this memoir been 

 received, that we intend to offer it shortly in book form ; a preface 

 to the work has been written by Prof. W. D. Miller of Berlin, and 

 Dr. Vicentini has appended a bibliography and other important 

 additions. The continuation of Mr. H. C. Vine's valuable papers 

 on the " Predacious and Parasitic Enemies of Aphides " has been 

 of great interest, and our best thanks are due to Mr. Vine for his 

 contributions. Our thanks are also due to Mr. C. D. Soar for his 

 papers on the " British Hydrachnid^," to Mr. W. Thomson for 

 his papers on " The Influence of Light on Life," and " On the 

 Study of the Micro Fungi," to our past-president, Mr. G. H. 

 Bryan, for his lucid article on "Benham's 'Artificial Spectrum Top,' " 

 to Mr. C. J. Watkins for his interesting contribution on " The 

 Denizens of an Old Cherry Tree," to Prof. V. A. Latham for the 

 valuable account of the " Methods and Formulae used in Examin- 

 ing Blood." The Presidential Addresses of Dr. H. L. Browne, 

 Dr. J. Hall, the Rev. E. T. Stubbs, and Dr. J. S. Turner also 

 deserve mention. Lastly, we must offer our best thanks for 

 the kind assistance we have received from so many of our 

 Subscribers.
