Description: | VI/4-17 (presumably the specimen number) MANU PONTERCORVO,Guido. before February 18, 1944 Glasgow University, Glasgow, Scotland. These are specimens of the testes or ovaries of *Pediculus humanus* the body louse named *Pediculus corporus* by Pontecorvo. They are imbedded in paraffin wax.
The fixative was Langlet's modified Navashin fluid. A chromic acid, acetic acid, formalin solution.
Nils Abraham Langlet (1868-1936) Swedish chemist. Sergei Gavrilovich Navashin (1857-1930) Russian biologist.
The stain was possibly one of the various preparations based on hematoxylin (Natural Black 1, derived from the logwood tree *Hematoxylon campechianum*)
The material is associated with a paper on fundamental studies of spermatogenesis and sex ratio in the human louse, Hindle and Pontecorvo, 1942. Pontecorvo fed the animals on his own blood. The specimens were x-rayed February 18, 1944. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
