In 1869 an outbreak of fatal trichinosis led to a series of articles published by various authors in the Canada Medical Journal.

Edwards was Lecturer on Chemistry and Toxicology at the Liverpool Royal Infirmary School of Medicine until 1866, at which time he emigrated to Montreal to join the medical faculty of Bishop's College as Professor of Chemistry and Microscopy. He is remembered today for his participation in the public discourse over William Fox Talbot's patent infringement lawsuit against Martin Laroche, writing two papers supporting Laroche 1, 2 which were published shortly after the end of the trial.

The name of Inglis is inscribed in the negative of the first plate, but given the fact that Edwards was an expert in the chemistry of photography there can be no doubt that he made the original photomicrographs that were then reproduced by Inglis.
