 the poisonous nature of the aniline dyes used for colouring stock- 

 ings. He stated that he had in his own possession eleven sam-

Dr. Dickson's death was sudden and distressing. It was 

 known that he suffered from serious mitral disease ; but for some 

 time prior to his death he had seemed to be in better health 

 than usual. On the 5th of January last he was reading in his 

 carriage on his return from visiting a patient, when his wife, who 

 was with him, observed that he bent forward and remained in that 

 position as though looking for something on the floor. He re- 

 turned no answer when spoken to, and on being raised was found 

 to be dead. He was in his 33rd year. Although comparatively

 and especially in botany. He died of fever and congestion of the 

 lungs at Salem, Madras, on the 21st of February, 1873.

 and for many years the active and energetic Secretary of the well- 

 known Zoologico-Botanical Society in that city, by the Members 

 of which his death has been felt as a severe loss. 



The exertions of Herr von Frauenfeld in the cause of natu- 

 ral history are evidenced by the long list of contributions to 

 Science entered under his name in the Eoyal Society's Cata- 

 logue. Most of these were published in the * Transactions ' of 

 the Society mentioned above ; but several of them appeared in 

 Haidinger's ' Berichte,' in the Eeports of the Academy of Vienna 

 and of the Geographical Society there, and in other publications. 

 They relate principally to entomology and malacology ; but the
