Cautions to he observed in the use of Paris-green. — The bags 

 should be labelled Poison and kept locked up, and especially 

 kept safely out of the way of children, who might be attracted 

 by the beautiful colour. 



Workers with the powder should not allow it to settle in 

 any sore or crack in the skin of the hands, nor stir it about 

 unnecessarily with the hands ; and they should be very care- 

 ful not to breathe in the powder through mouth or nose wliilst 

 measuring or mixing it. 



For this reason it is most desirable that purchasers of Paris- 

 green should have it sent not in bulk, to be divided for use on 

 receipt, but wrapped in single pound (or small) packages by 

 the senders. I particularly wish to draw attention to Mr. 

 Dixon's observations on this head, given in his replies to my 

 enquiries : — 



" In handling this article in the dry powder, care is required, 

 as a light green dust arises, which is breathed in, and produces 

 unpleasant results ; and in one instance a customer who 

 thought he could save money by buying it from us in bulk, 

 putting it up himself in paper parcels, employed a man to 

 weigh out and wrap about 5 cwt. in 1 lb. parcels. This cost 

 the man his life ; so as we are laid out for this business, some- 

 times wrapping 10 tons in a week, we can really do it at much 

 less cost. 



" We have never heard of any accidents to users in America, 

 and there is no danger when using it in water " {i. c., from its 

 flying about, E. A. 0.) ; " but you might advise any who wish 

 to try dusting it on dry to carefully stand to windward." — 

 (E. Dixon (Director), Messrs. Bluudell & Spence, Hull.) 



Messrs. Blundell & Spence, will now, if wished, send out 

 small orders damped, which saves all risk or danger from 

 powder flying about. 



Sheep or other animals should not be pastured or allowed 

 to feed beneath trees that are being sprayed, or have recently 

 been sprayed with the " green." 



In fact, ordinary care and caution should be exercised ; like 

 many other poisonous mixtures this may be used without the 

 slightest danger or damage, (/"reasonable care is used ; if not,
