 any, we find, are new to the district.

 observations on the subjects named, especially those 

 dealing with the anatomy.

W. G. B. — We thank you for your letter and good 

 wishes, and shall be very pleased to receive your

 obtaining them. Any of the dealers who advertise

 dealers will charge you much more.

 While agreeing with your arguments in favour of 

 such a Society, which is no doubt much needed, we 

 could not take the initiative in such a matter.
