Note :
In the "Canada Medical Journal" for 1870-1, Dr. J. B. Edwards has published a full account of the best methods of detecting trichinae in the flesh of man and animals. He has furnished me with some excellent photographs of the worms in situ in human and animal cuscle, of which engravings are annexed. In some cases which occurred at Montreal, the cause of the symptoms was at first obscure, but Dr. Edwards not only found trichinae in a slice of ham which had been eaten, but in the muscles of two of the patients who recovered. He removed about five grains of muscular tissue from the gastrocnemius muscle, and twelve grains of the tibialis posticus. In both of these portions of muscle about forty worms were found. 1
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 2-3 which were published shortly after the end of the trial.
