ankle, causing her some pain and uneasiness in walking. This 

 swelling gradually shifted its position and slowly moved up the 

 leg, thence towards the right axilla, then down to the elbow, and 

 finally settled on the back of the neck. In this position a small 

 dark spot appeared, an orifice formed ; and when pressure was 

 made around this opening a white grub, nearly an inch in length, 

 protruded, and escaped along with some unhealthy pus. Several 

 other similar swellings developed upon subsequent occasions 

 under medical observation, and the medical man extracted other 

 grubs, exactly similar to the first specimen. No cause could be 

 assigned for these curious phenomena. The larvae were pro- 

 nounced by competent authority to belong to a dipterous insect, 

 although the genus could not be satisfactorily determined. There 

 was no sufficient proof of the existence of an oestrus peculiar to 

 man alone. A good abstract, from which the above is quoted, 

 appeared in the ' British Medical Journal,' October 1st, 1881. I 

 shall feel grateful to any of your readers who will give additional 

 information or references. — William E. A. Axon; Fern Bank,

Note on the use of Naphthaline in Cabinets for the 

 PROTECTION OF Insect COLLECTIONS. — In the 'American Natu- 

 ralist' for May, 1883, p. 409, which Prof. C. V. Kiley has most 

 kindly forwarded to me, I find that " Mr. C. A. Blake, of Phila- 

 delphia, has been preparing cones of naphthaline run around a 

 pin, so that they may be stuck into a box of insects, and that the 

 naphthaline may permeate the box and last for a considerable 

 time. They are made after a formula recommended by Drs. 

 Le Conte and Horn, and are very convenient to handle. They 

 gave such promise of usefulness that we obtained quite a lot of 

 them, and went to the trouble of supplying all our insect boxes 

 with the same. We have speedily rejected them, however, and 

 give this note of warning, especially to lepidopterists, to whom 

 they will prove particularly objectionable, as our experience of a 

 few weeks suffices to show that they very quickly encourage 

 greasing, and soon produce a relaxed, sordid, or greasy apj)ear- 

 ance of the insects. Another objection is that by deliquescence 

 the pale chocolate colour of the cones connnunicates to, and 

 discolours, the lining of the boxes wherever it comes in contact 

 therewith." I am not aware that in England such a preparation 

 of naphthaline is ever used; but the object of my note is to
