He died at only 24 years of age, soon after returning from his African trip, having collected a large number of natural history specimens including over 2000 insects.
Victorin suffered chronic tuberculosis, which eventually led to his death, and in an effort to convalesce he left for the Cape of Good Hope.
He happened to meet fellow naturalist Johan August Wahlberg, who advised him to extend his travels to the eastern parts of the Cape.
He became acquainted with members of the George Rex family, travelled to Plettenberg Bay, with excursions to Westford and Redburn.
Returning to George he crossed over Montagu Pass into the Little Karoo, staying on the farms Roodeval (now Van Wykskraal) and Zeekoegat, near Oudtshoorn, until February 1855.
He also collected 31 bird's eggs (11 species), some 2000 insects, several shells and other invertebrates, plants, seeds, bulbs, and lichens.
