IV. PREFACE. 



the ranks of literature, our aim being simply to give such a 

 description of it as will at once satisfy our readers that it is, or 

 is not, such a one as they may require. 



It is with much satisfaction that we look back to the work 

 of the past year ; it was a period of great labour^ and of much 

 anxiety, which however has borne goodly fruit, and we beg very 

 cordially to thank our numerous contributors for their valuable 

 papers. Our thanks are also due to Dr. Muter, Editor 

 of the Analyst^ for permission to transfer to our pages the 

 interesting paper on Microscopic Crystallisation, and for the loan 

 of the blocks from which the plates illustrating it were printed. 



Nor must we omit to thank very heartily our many subscribers 

 for their generous and Uberal support. We are pleased to be 

 able to inform them that we have a number of very excellent 

 papers in store for our Sixth Volume. AVe also beg to state 

 that a General Index is in preparation, and will be issued with the 

 October part of Vol. VI.
