so TEE ANALYST. €'AR,IX MUNICIPAL LABORATORY. On another page we print the report of the Paris Municipal Laboratory for the month of February. We should be glad to print these returns every month if our spaco alIowed of it, as they shew strikingly the activity with which this useful legisla- tion is enforced in Paris, as compared with the apathy shewn in England, and espscially in the metropolis. There are several points in the return which will be of interest to our readers, in view of the amendment of the Act, which must naturally take place in this country in a short time. Milk adulteration appears to be almost as prevalent in Paris as in London, for we find that more than 30 per cent. of the samples bought by the Inspectora were watered and skimmed. The most reniarlcahls feature in tho return is the extent to which the falsification of wine is practised in Paris, and the stringent standard set up by the Municipal Laboratory f o F judging by.Thus me find that a disagreeable flavour, fortification with alcohol or sugar, or the addition of salicylic acid, are all sufficient to place samples in the '' C " or '' Bad '' class. We notice also that more than 25 per cent. of the samples of wine were condemned on the ground that they were plastered with two grammes per litre, and ,that 24 samples nre condemned as adulterated with €oi*eign colouring matters. It mill be observed that in chocolates, 8 samples were condemned on the ground of the acldition of the debris froin the shell and starch, and 9 samples are condemned for the addition of foreign fats, which we ppesume have been added to replace the cocoa butter. This adulteration is said to be very common in this country, but we have not yet met with a case of prosecution SOT it.Thirty-two samples of tin ware and glazed pewter were examined, and 27 of them mere condemned on account of the presence of lend, Colouring matters, toys, and colourecl papers and wrappers me dealt with very stringently, though, in our opinion, not too much so. Only two samples out of 3 1 rmmineci passed satisfactorily.81 l__l--- - THE ANALY8T. --_ -----I- --- ANALYSES MADE DURING THE NONTH OF FEBSUARY IN THE MUNICIPAL LABORATORY O F PARIS.
