deeply our numerous readers are int rested in the subject of 

 another General Index. We are aware the vols, of ScrENCE- 

 Gossip for the last twenty-five years are the best Cyclopaedia 

 of Natural History in the world. 



D. H. Stuart Sthwakt. — The specimen you sent us of the 

 abnormal var. of the white willow [Sali.x alba] was very 

 interesting, and v/e are much obliged to you for it. 



D. H. S. S. — "Spiritualism" and "Mesmerism" hardly 

 come within the scope of Science-Gossip; but we think the 

 Secretary of the London Spirituali-t Society would siipply 

 you, if asked, with a li^t of the best books on those subjects. 



F. H. P. CosTE. — Your letter must someway have gone 

 wrong, for we have not received it. Please send us your
