25 per cent of ita whole weight. This substaace is a peculiar unstable alkaloid, de- 

 stroyed at 60° C, or by alcohol. Introduced into the circulation of warm-blooded 

 animals, one-thirtieth of a milligram per kilogram of the animal treated was sufficient 

 to cause death. It exceeds in power all known vegetable principles and prussic acid> 

 being comparable in toxicity with the poison of snakes. 



The following- two letters also bearing on the subject are appended, 

 the first of which is from Mr. E. Allau Wight, of Xew Zealand : 



What Dr. Wright told you about the Katipo is perfectly correct. I was then liv- 

 ing close by and knew all the parties and all the circumstances, and my sous also re- 

 member it all. It was as clear a case of Katipo poisoning as possible, and the man 

 Said he saw the spider bite him and minutely described the spider, which description 

 tallied exactly with its proper one. A case occurred at Wliatigarei a few weeks ago, 

 where a man was bitten and sutt'ered a good deal, and I have written to the medical 

 man who attended him aud will let you know the result. I am also going soon on 

 another long tour in the north, where I shall be able to get many tales and reliable 

 information from both natives aud white men as to the Katipo, aud will let you know 

 when I come back. I drove over to a man who is said to have lost his arm " through a 

 Katipo," but I found that he does not know one when he sees it, did not see the bite in- 

 flicted, was in a place where the Katipo does not live, and when the arm was re- 

 moved the bone was diseased ("honeycombed"). That is one of those tales peopjehear 

 and which make it difficult to believe anything. I feel certain the Katipo is a ver^' 

 dangerously poisonous spider, but I never but once saw a case with my own eyes. It 

 was many years ago aud I was out with a war party of Maoris ; one uight we found 

 ourselves in au unpleasant position as far as they were concerned. On our rear there 

 were a number of nice hollow places to sleep in, but as these were Maori ovens, in 

 which men had been cooked for a cannibal feast, the natives not only would not sleeji 

 in them but they would not let me ; so we lay down on the bare shiugle beach with no 

 teut in a high wind, aud before us at a short distance was au island that is (they say) 

 inhabited by evil spirits ; so with spirits both before and behiud we lay awake talk- 

 ing in subdued whispers. 



I had my head on a rush bush, but they would have me shift it on to a rock, be- 

 cause they said the Katipo lived in the rushes by the sea-side. I was anxious for 

 them to sleep, knowing that tomorrow we would want all our strength, but it was 

 no use, for by aud by a man screamed out that the Katipo had bitten him, aud in a 

 moment lights were brought, aud sure enough the Katipo was there within a foot of 

 the wound under his mat. The arm swelled, but not so much as to give alarm. What 

 alarmed me more were his weakness and languor and the lowness of his pulse aud 

 his heart _action. The poison certainly was a powerful narcotic, if symptoms go for 

 anything. I gave him all the brandy we had, and the natives pretty well burned his 

 wound and rubbed aud nibbed at him till they got him into a perspiration, but he 

 did not properly recover for several days, and if oue had only known it would have 

 been a mercy to have let him die (which I believe he would) ; so I thought when I 

 saw him gasping his life away with blood aud froth flowing from his mouth. Ugh! 

 That is one of the several scenes I do not care to think about. By the by, I could 

 not get the specimen ; the Maoris burned it, as they said the Katipo is an evil spirit 

 and if tve did not burn it the man tvould die. I never heard of any Katipo but oue; 

 I think Taylor is mistaken. I have mauy chiefs here, and I asked them only to-day, 

 but no one ever heard of but one Katipo — the black spider with a vermilion spot on 

 the abdomen. * * * . — [R. Alia n Wight. 



Immediately after reading Dr. Corson's interesting article on Spider Bites in the 

 March number of Insect Life I went into a partially darkened room aud drew ou 

 my bare feet a pair of felt boots that had been unused for some time. Simultane- 

 ously I received a sharp puncture ou my ankle.
