stockinet, or cotton cloth, usually the former, is passed through the 

 cylinders at the same time with the " hatch " of gum, which by this pro- 

 cess completely coats it. From this the gloves are cut and joined by 

 covering the edges with strips of heated rubber. These gloves are made 

 of a variety of colours, are very soft and pliable, and have a very neat 

 finish. They are very useful in domestic pursuits and gardening, and 

 to be worn in all kinds of employment likely to discolour the hands. By 

 protecting the hands from the atmosphere, and retaining the insensible 

 perspiration, they soften them and increase their whiteness ; and often 

 prove a cure for chapped hands and salt-rheum. The joining of these 

 gloves is done by women, and is considered a healthful and profitable 

 employment. We do not learn that there are as yet any silk or cloth 

 gloves made in this country. 



ON THE REVERSION AND RESTORATION OF THE 

 SILKWORM. 



BT CAPTAIN THOMAS HUTTON, F.G.S., 

 (Concluded from page 189.) 

 Having- been frequently applied to from different quarters for infor- 

 mation as to the best kind of mulberry leaf on which to rear the silk- 

 worm, it may be as well perhaps to give the result of my own experience, 

 and leave each inquirer to please himself as to the species he may find 

 it most convenient and most suitable to adopt. 



The question then is, " what species of mulberry tree is best adapted 

 for the nourishment of the silkworm, and for the production of good 

 silk?" 



Were all climates alike the question might be easily answered, but 

 in its present form it is too vague and general ; besides which, thus put, 

 it assuredly implies a belief that we have only one species of silkworm 

 under cultivation, and that whether monthly or annual, all come under 

 the head of Bomoyx mori. This, however, is not the case, the name of 

 B. mori belonging of right to the worrn.known in India as the Cashmere 

 worm, which is an annual, and is cultivated in Afghanistan, Bokhara, 

 Persia, Syria, Italy, France, and other European countries. It was 

 originally brought lrom the northern provinces of China, where the 

 country is mountainous, and the climate, especially in winter, very 

 severe and cold. There is also another worm cultivated as an annual in 

 Bengal under the native name of Boro-poo loo, which means "large co- 

 coon," it being the largest species of Bomoyx under cultivation in 

 Bengal. As compared with the cocoon of the Cashmere worm, however, 

 it is very much smaller, of a • different form and texture, and yielding
