After ten years, when fingers had progressively slightly more curled up, the subject discovered that voluntary movements of adduction and abduction became easily possible just by pressing the hand on a flat surface. Persistent voluntary hand motility was then partially obtained through specific self-trained exercise. The increase in the abduction angle was easily measured with a proctor and this is proposed as a simple clinical test to assess the improvement due to training. The case is analytically described.

They had the opportunity of looking at each other or not, and this chance was considered. The rabbits were firstly introduced in the upper floor and their behaviour was video-recorded each 12 minutes for 13 days. The trial had four replications to a total of 12 subjects. Since it was observed an initial explorative activity performed mainly during the second day, but with peculiar behavioural differences among subjects, this aspect was later studied in a second trial, by continuous video-recording of 3 rabbits. After a few days, the rabbits chose to lay preferentially in the lower floor (80.7% of the time; P< 0.01). The trend was already clear at the 3rd day (lower floor 74.1%; P<0.01), while, during the second day, the explorative activity equalized the percentage of presences (50.9% lower floor vs 49.1% upper floor; P = n.s.). When rabbits had the chance of looking at each other they did it mostly. On the 2nd day this behaviour was slightly reduced as an effect of the explorative activity. From the 4th day rabbits located in the external cages were looking toward the subject nearby in the central cage 76.2% of the observed occurrences (P<0.01). The general trends could be observed as a mean notwithstanding rabbits showed individually specific behaviours. The results of the second trial showed that rabbits have different latency periods, in a range of 20 to 47 hours, before beginning the explorative activity.

Leonardo never finished the work looking for an appropriate physiognomy. The thesis is that, at the end, he was inspired by Signorelli.

The two heads of old bearded men analysed by Martin Clayton. The Royal Library at Windsor Castle. Martin Clayton, dating the drawings to the last decade of Leonardo's life, with reference to the head on the left writes: "We know that Leonardo himself had a full beard at this time, and an old bearded man drawing an old bearded man cannot have been oblivious to an element of self-portraiture", and with reference to the head on the right writes: "Leonardo must have been conscious here of some element of a self-portraiture.....A drawing such as this, with no preparatory purpose and retained by the artist, surely expresses some of Leonardo's feelings about his own physical decay". 2 The words that have been reported in italics show clearly what the Author's reasoning guesses, as to say that Leonardo is representing himself. The aged person represented in the drawings with long hear and beard does not have the traits of distinguished dignity in comparison with the most known representation of Leonardo's face, but some consequences emerge if, on the contrary, the drawings are considered as true Leonardo's self-portraits according to the suggestion by Clayton with reference to Leonardo's physical decay. Let the hypothesis of work be then that the two drawings in the figure 1 3 represent the real aspect of old Leonardo's face. If this is so and we look at it carefully we will discover a peculiar anatomical trait that can be observed because, on one hand the ear is not covered by hair, and on the other the ear can be seen even if the hair (strange peculiarity) should cover it. It is clear that in both cases the upper border of the auricle is bent forward. This is a very uncommon anatomical peculiarity and the two drawings represent consequently the same person. The short ear lobe, the form of the mouth, the long fleshy nose ending at the level of the mouth, the thin lips, the prominent cheekbones, the shape of the eyes, the baldness at the top of the head and the
