We call particular attention to this matter as we have more than once traced up the cause for a complaint of the quality of some particular shipment of the Preservative to the fact that the customer has had one or more kinds of “_fluid_” on hand and in some careless moment has emptied back some little left over, into the package containing our Preservative to its very great injury. Even keeping the Preservative in wood totally destroys its efficiency as an Embalming preparation and therefore it should never under contingency be kept in wooden packages. It should always be kept in the glass packages in which it is shipped, or in some other glass vessel. Every package that is sent out is exactly like every other package in regard to the quality of the Preservative it contains, and its contents will never deteriorate in any length of time it may be kept providing that no other substance be added. APPENDIX. TO OUR CUSTOMERS: We have appended to the foregoing treatise on Embalming some few of the letters we are constantly receiving from our customers, giving their unbiassed opinion of the merits of the Excelsior Preservative, entirely unsolicited on our part and without the least idea of publication on the part of the writers. To such of our good friends and customers who find such an expression from themselves printed in this book, we ask pardon for the publicity given to their letters, trusting that the good company in which they will find themselves, among the leading members of their profession, will be our best excuse for the liberty we have ventured to take. Want of space prevents us from printing but a very small portion of the thousands of commendatory letters we have in our hands, and for the same reason we print only such portions of the letters as will fairly give the opinions of the writers thereof. Respectfully yours, CRANE & ALLEN. Commendatory Letters and Extracts. New York City, Jan. 21, 1886. CRANE & ALLEN: Please duplicate the last bill of your Preservative sent to us—56 gallons I think. It has given us great satisfaction. STEPHEN MERRITT. And again April 30, 1886. CRANE & ALLEN: Please send us as soon as possible one hundred gallons of your Preservative. Let one carboy come by express at once. The Preservative gives perfect satisfaction. STEPHEN MERRITT. * * * * * Newton, Kansas, Aug. 3, 1887. CRANE & ALLEN: If you will please to duplicate the invoice of May 11th. (13 gallons) you may do so at your earliest convenience. We like the Preservative very much and will use no other as long as we can get as good from you.
