Abstract:
The crime possibly perpetrated by a doctor named Vicente Urbino de Freitas in 1890 is one of the most famous cases of poisoning, and it had echoes in the Portuguese and foreign press for several decades. This prestigious doctor was convicted of the fatal poisoning of his nephew. He also attempted the homicide of two nieces and their mother-in-law, who only escaped because they obstinately refused to comply with the "therapeutics" prescribed by the family doctor. The motive of the crime should have been Vicente Urbino de Freitas' ambition to receive the family inheritance of his wife, the daughter of the well-known merchant José António Sampaio of Flores Street in Porto. Vicente Urbino de Freitas was convicted but doubt about his guilt persists for more than a century. This second work aimed to collect and analyse all the relevant and contradictory testimonial evidence of the prosecution and defence witnesses. This case represents an odd historical record obtained through more than 12 years of research on the first major significant Portuguese forensic case. Rare and unprecedented testimonial evidence and photographs were obtained from different countries and then repaired, since these also provide an important historical record of the medical photography.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
