Unità documentaria 0055 - Letter from Joseph to Lorenzo thanking him for the interest he had taken in their welfare and he is sure that his efforts will be rewarded. He mentions the Aquarium on Madras Beach where one can see the tropical fish in its natural state. Says that if one wants to start this attraction it would surely not be a failure and hopes that the museum of natural history would take this up. He recalls that on the 6th it would be the 20th anniversary of his first graduation in medicine.
