There is no botanical communication in either number, but the 

 usual supply of short notices. We have to thank the editor for the fa- 

 vourable notice he has been pleased to take of our labours ; the Ma- 

 gazine of Zoology and Botany was neither begun in rivalry, nor 

 from a wish to injure in any way the Magazine of Natural History, 

 for the plan and object of the two works were at first essentially 

 different, and there is still a specific distinction, which a careful rea- 

 der will be at no loss to perceive.
