172 Review. 



Aidone, in a boy of five years of age, vaccinated Septem- 

 ber 28, the disease appeared on the 20th of October. 

 In a girl, vaccinated by me on the 8th of December, the 

 disease was visible after the fourth day of the operation, 

 and gave clear signs, that it had taken effect. From 

 this period, it made such slow progress, that, on the 

 26th of the same month, the vaccine pustule could 

 scarcely supply virus sufficient to vaccinate other chil- 

 dren. 



** I observed in two patients*, that the vaccine pus- 

 tule regularly appeared on the fourth da}-, dried on the 

 seventh, and fell on being slighdy touched by my finger. 

 I made an incision through the middle of one of them, 

 and found a coagulated humour in the centre. 



*' In many vaccinated, during the state of inflamma- 

 tion, some red spots were se'^n, which spread similar 

 to those of the Scarlatina, and disappeared in a few 

 days. A miliary eruption happened to others, bright, 

 of a cineritious colour, elevated above the skin, without 

 any redness, which gradually vanished in a short time. 

 But sometimes such eruptions have been accompanied 

 by redness, followed by a suppuration scarcely visible, 

 which, from the third or fourth day of its appearance, 

 dried, and presented a whitish scalef.
