relieve the pain, but not offering a word of caution as to there 

 being any danger if an over-dose was taken. The )3ain getting 

 much worse, I took a third of a dose more than his prescrip- 

 tion : this soon produced all the horrible symptoms of 

 poisoning by strychnine, which I need not describe. Thanks 

 to the kindness of Mr. Timms, at whose house 1 was spending 

 the evening, my life was saved, he driving me instantly to my 

 friend Dr. Weld. On subsequent inquiry the chemist 

 informed us that in that bottle of eight doses there was 

 sufficient strychnine to quickly kill three people ! 



Since sending you the notes, I have come across a bad 

 specimen of Lampides Boetica, also taken near Nairne. 



The butterflies at present named are as follows : — (1) Thyca 

 Aganippe, a few ; (2) Callidras Lactea, one ; (3) Heteronympha 

 Meropa, abundant ; (4) Geitoneura Klugii, not common ; 

 (5) Junonia Villida, common ; (6) Danais Chrysippus, com- 

 mon; (7) Vanessa Kershawii, abundant; (6) Lucia limbaria, 

 not common ; (9) Terias Igana, a few; (10) Lampides Boetica, 

 one; (11) Lycaena Phcebe, swarming everywhere.

PART I. 



There are three principal natural divisions of land on the 

 earth, — Asia, Africa, and America ; Europe being considered 

 as the western part of Asia. Each of these forms two subdivi- 

 sions connected at the equator, and having their base in the 

 tropics, and extending more or less, — the one towards the 

 north pole, the other towards the south pole ; and the 

 resemblance between the productions of these six subdivi- 

 sions have been considered to be owing to continents which, 

 in early lime, have gone up and down in the intervening 

 spaces. In America the land to the south, exclusive of some 

 antarctic islands, forms one compact region, which tapers 

 from the tropics to Cape Horn ; and some of the insects in 

 the districts near this Cape resemble, as has been observed 

 many years ago, other insects in North America and in 

 North Europe. The land to the north is interrupted by the 

 Caribbean Sea and by the Gulf of xMexico, beyond which it
