NOTES AND OBSERVATIONS. 



Exhibition of the South London Entomological and Natural 

 History Society. — The Thirteenth Exhibition of this Society was held 

 at St. Martin's Town Hall, Trafalgar Square, on Oct. 17th last, and 

 was evidently a great success. Not only was this so as regards the 

 extensive and varied character of the material brought together, which 

 was in the highest degree both interesting and instructive, but also 

 from the fact that the attendance was a large one. On this occasion 

 those on whom the arrangements mainly devolved had a much larger 

 space than formerly at their disposal ; but the result proved in a very 

 satisfactory manner that they were quite able to utilise this to the 

 fullest advantage. Entomology, especially the Order Lepidoptera, 

 was well represented, and the Hon, Secretary's Report on exhibits in 

 this department will be found on page 300. — Ed. 



Grease in Moths. — This being the greatest trouble I have had 

 with my collection, I have tried nearly every remedy that has been 

 suggested. While studying Dr. Guard Knaggs's remarks on this sub- 

 ject, however, I noted thnt he considered that grease was practically 

 the result of decomposition, and the thought occurred to me that 

 criminals were buried in quick-lime to prevent ordinary decomposition. 

 Wondering how slaked lime would act, I got some, powdered it up 

 finely, and put it in a box, resting the win^s of some "greasy" subjects 

 on it. I covered the bodies, having first cut off a portion of tbe under- 

 side, and extracted as much of tbe contents as possible. When this 

 was done early it cleaned them better than anything else I have tried, 

 as when the grease is absorbed, and tbe body is well dried, a camel- 

 hair brush removes the lime nicely, and you can finish off by brushing 

 upwards. The lime does not seem to harm the wings or pins at all
