HE present issue is the Third Volume of our Journal 

 which we send forth to the world, assured that it will 

 receive the same welcome in the homes of Scientific 

 men, both English and Foreign, which has been 

 accorded to the previous volumes. 



The completion of the third year of the existence of 

 any Scientific Journal, is, in many respects, a season for much 

 congratulation, for it not only marks a successful passage through 

 the many, and in most cases, inevitable difficulties which beset 

 the infancy of publication, but at the same time, the character 

 of the work becomes increasingly more decided and apparent. 



The change of title adopted with the present Volume, 

 has allowed us somewhat to diverge from the paths of pure 

 and simple Microscopy ; whilst at the same time, no article 

 has been inserted that has not come fully within our present 

 sphere ; and we may now hope that the merits of the " Journal 

 of Microscopy and Natural Science " are fully established before 

 the public, and that an abundant success will speedily reward 

 our labours.
