Before I conclude, I shall repeat what I already stated in a previous report, that the sending of live cocoons and pupæ from India and other distant countries to Europe, can easily be done, so that they will arrive alive and in good condition, if care be taken that the boxes containing these live cocoons and pupæ should not be left in the sun or near a fire (which has been the case before), and that they should at once be put in a cool place or in the ice-room of the steamer. The cocoons and pupæ should be sent from October to March or April, according to distance, and it is most important to write on the cases, "Living silkworm cocoons or pupæ, the case to be placed in the ice room." By taking this simple precaution, live cocoons and pupæ, when newly formed, can be safely sent from very distant countries of Europe. To continue these interesting and useful studies, I shall always be glad to buy any number of live cocoons, or exchange them for other species, if preferable. ALFRED WAILLY. 110 Clapham Road, London, S.W. * * * * * MOSQUITO OIL. A correspondent from Sheepshead Bay, a place celebrated for the size of its mosquitoes and the number of its amateur fishermen, recommends the following as a very good mixture for anointing the face and hands while fishing: Oil of tar. 1 ounce. Olive oil. 1 ounce. Oil of pennyroyal. ½ ounce. Spirit of camphor. ½ ounce. Glycerine. ½ ounce. Carbolic acid. 2 drachms. Mix. Shake well before using.--_Drug. Circular_. * * * * * THE CATHEDRAL OF BURGOS. This most remarkable structure, in the province of the same name, adorns the city of Burgos, 130 miles north of Madrid. The corner stone was laid July 20, A.D. 1221, by Fernando III., and his Queen Beatrice, assisted by Archbishop Mauricio. The world is indebted to Mauricio for the selection of the site, and for the general idea and planning of what he intended should be, and in fact now is, the finest temple of worship in the world. This immense stone structure, embellished with airy columns, pointed arches, statues, inscriptions, delicate crestings, and flanked by two needles or aerial arrows, rises toward the heavens, a sublime invocation of Christian genius. Illuminated by the morning sun it appears, at a certain distance, as if the pyramids were floating in space; further on is seen the marvelous dome of the transept, crowned with eight towers of chiseled lace-work, over the center of the church.
