Mr. C. Suffreu lias invented an ingenious diagranimatic 

 method oL' recording migration as observed in the Mediter- 

 ranean. He believes that apart from the well-known

 routes across the Mediterranean, i. e., Riviera, Corsica, Sar-

 Crete, Egypt,

 Hebrides by Miss Audrey Gordon; and finally. Col. Feilden
