OF WASHINGTON. 141 
Mr. Dodge said that Dr. Palmer was bitten on one occasion 
on the hand, and three months after, when he saw it, the hand 
was very much puffed up and inflamed, and in a very ugly con- 
dition, though Dr. Palmer said it was then very much better, and 
was healing. 
Mr. Schwarz suggested permanganate of potash as a remedy. 
Judge Johnson said that he had once upon a time investigated 
a number of spider-bite cases, but without ever getting any posi- 
tive proof, so he had never published the result. 
Dr. Marx said that he had investigated one case of a supposed 
death from spider bite in Washington, D. C., which resulted in 
showing that the victim had gone to sleep at night and had 
awakened in the morning with a pustule on the neck, which 
rapidly inflamed and enlarged, and eventually caused death. No 
one had seen any spider, and the assumption that there had been 
one was utterly unfounded, yet the case was published everywhere 
as an undoubted one. 
Dr. Fox thinks there is probably some basis for some of the 
accounts, and thinks that under some physical conditions the bite 
might become dangerous. 
Mr. C. R. Dodge exhibited impressions from some of Glover's 
early plates, and gave an account of Glover's experiments in various 
methods of engraving on stone and metal, and of his manner and 
system of work. 
There was some discussion on the drawings shown, and on the 
relative value of the various processes in producing good entomo- 
logical results. In this Messrs. Marx, Schwarz, Smith and Lug- 
ger took part. 
Mr. Howard presented a note describing an external parasite on 
a spider found by Dr. Fox about the middle of February.* 
Mr. Schwarz said that to him the most interesting point was 
the season at which this parasite was found. It was so early in 
the spring that it seemed scarcely likely that it had attained its 
present development from an egg deposited this season. The in- 
ference was that it had hibernated with its host. 
There was considerable general discussion on external para- 
sitism, and the possibility of molting in the larva so infested. Mr.
